Help troubleshooting networking problem...

I apologize for calling this a "networking problem," I just don't know how to title it...
Basically, I'm looking for help tracking down an odd problem on my MacBook. It mostly manifests as incomplete web requests.
I'll try to explain.
I'll go to a website, which starts a browser downloading images and what not. Most times, I never get the entire web page. For instance, on this very page, the bottom of the browser (Firefox) says, "Waiting for images.apple.com" and the circle is spinning at the top. This unresolved request, whatever it is, is unlikely to complete.
Here's what I've tried:
1. Updating my wireless router. (Netgear G. I honestly don't notice this problem on other systems in my office, though.)
2. Changing web browsers. (It affects others, too.)
3. Creating Mozilla profiles.
4. Surfing in different Mac accounts.
5. Clearning browser caches/cookies/etc.
6. Turned on/off interference robustness on the AE.
I'm not looking for a solution (unless you have one). I am looking for some new ideas on troubleshooting the problem.
What's most annoying is that the problem is GASP intermittent. I may do one of the above things, for instance, and it seems like the problem goes away, but it comes back eventually. And it also eventually leaves for a period of time if I do nothing.
It feels like a networking issue, something outside the Mac -- wireless interference or something, but ... I just don't know.
Thanks.

I should have mentioned that I tried that.
There are a couple of APs in the neighborhood, one is a Belkin Pre-N with Airgo's chipset. The only reason I mention the Belkin is that there have been some news reports that suggest Airgo's wireless management degrades regular B/G wireless devices in the area. I don't know how true that is.
Anyway, it seems like I've solved it.
I surfed wired for about two days and was able to determine that the problem was related to wireless communication. Now, whether it was my Airport Extreme or my Access Point...
My Access Point was one that was given to me by a customer. She didn't need it any longer. It was used and I didn't really know how it performed. I can say that one of the things I did before all these problems started to take place was install that AP.
I replaced the AP this weekend. I decided I would just try a new one.
That seems to have fixed it. I do get the occasional hangup. (I do an awful lot of surfing.) Mostly I see the hangups now on pages that have an abnormally high amount of connections to external sources. An example of this is the dynamically generated Newsgator RSS feed page. This page goes out to all manner of websites to grab images and what not and I sometimes see hangups there, but that's about it.
This is good news. I was worried my Airport Extreme was to blame. But, you know, even my wife's laptop (PC) is performing better wirelessly. There was a problem in that Access Point. I had updated the firmware just the week previous to see if that would fix the problems I experienced, but no...
Anyway, I kind of needed to talk this out. I appreciate your help!

Need help troubleshooting: booting problems

I'm a bit stuck troubleshooting and could do with some advice.
A quick backstory: my mid-2010 13" MBP started to refuse to boot and displayed the flashing question mark, so the Geniuses replaced the hard drive connector cable - which sorted the problem for a few months.
So the flashing ? reappeared and I've tried a few fixes but need advice on where to go now, I think it might be a RAM problem.
What I've tried so far:
I've tried erasing and then verify and repair the HD through disk utility, using the OSX DVD, which came up OK.
Reset NVRAM
Clean Install: the HD would show up, but would fail after 30 mins; "Install failed... could not copy the necessary support files."
Ran Apple Hardware Test: showed error 4mem/4/40000000 0xabd93398
Took out each RAM card separately, cleaned with compressed air, tried out each one separately in either slot - still get a flashing ? on startup.
Any thoughts on what I could do would be really appreciated. Thanks for any advice!

If the OS installer failed removing RAM will not fix the damage.
The question mark means a bootable OS couldn't be found. You will need to reinstall the OS & see if the Mac stays stable. You may need to do this with one RAM module to see if the other is causing the crash. The AHT message is a RAM error, re-run the test & change modules to see if it is a particular module or slot that causes it.
You can try booting from external disk to try to rule out the internal HD, but that isn't a practical solution for a laptop, it's more to help diagnose where the fault could be.
You could take it to an Apple store to see if they can help, but I doubt there will be any chance of repairs unless you pay. The first visit will be free, but there is a limited amount of testing that can be done.

Need Help Troubleshooting Mysterious Problem

The Basic Symptom:
After running an indeterminate (usually under 5) EJB operations driven from my web app all subsequent requests result in a browser stall wherein the progress bar inches ever so slowly toward infinity but never returns the requested page. The situation does not install until I close the browser and re-run the application.
My Configuration:
Oracle 8.1.5 on Windows NT
JDeveloper 3.0
Oracle Web-To-Go internal http/jsp/servlet engine as supplied with JDev 3.0
My Architecture:
Basically, I've got a number of .jsp pages which create session-level beans on startup. Each bean, in turn, grabs and holds a connection to a companion stateless EJB to service the session's requests.
The EJBs act as factories for standard java class files which are passed to the client (web/presentation) tier, are modified by the client via their browser session, and are returned to the EJB factory to be saved to the database (Oracle8i tables).
Please for Help:
Does anyone know if this is a known problem with any or all of the below:
a) My architecture (Please God NO!)
b) JServer and EJB handling (This would suck but maybe 8.1.6 would cure it)
c) A limitation of Web-to-Go's functionality
d) Something I'm not thinking of as a possibility???
ANY HELP YOU CAN PROVIDE WILL BE GREATLY APPRECIATED! (I HAVE TO DEMO THIS APP AS A PROTOTYPE ON THURSDAY AND DON'T WANT TO HAVE TO INCONSPICUOSLY STOP/START IT AGAIN AND AGAIN TO AVOID HANGS...)
Thanks in advance!
Will
null

Some additional information...
I can trace activity from the .jsp code to the webBean code. When the webBean code attempts to call a method on an EJB it never receives a response.

How can I pair my iPhone 4 to my computer via bluetooth?

Actually you can if you have tethering on your phone. I tether via bluetooth with my macbook air all the time. It will only pair if you have tethering turned on and if your carrier supports it. Otherwise it will not pair.

I try signing into iMessage and it takes about 45-50 seconds to do. When that happens it tells me there is a network problem. I am positive I don't have a network problem and I need help on this problem please??

Try resetting the SMC Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
and PRAM How to Reset NVRAM on your Mac - Apple Support
If those don't help you can try a cleaning disc or a quick shot of compressed air. Chances are that your drive has failed, join the club it's not all that uncommon. You can either have it replaced or purchase an inexpensive external drive. Don't buy the cute little Apple USB Superdrive, it won't work on macs with internal drives working or not.

Help with Boot Camp Assistant network problem while downloading windows support system!

I need to download Windows support software, but just keep encountering a problem which says "Can't download Windows Support Software because of a network problem." What should I do?

I have n iphone 4 with a talkmobile contract sim. I cannot send or receive msm. I have spoken to talkmobile customer service, my phone settings are correct,Aple say it 8is a network problem!! Help!!

talkmobile is not a supported carrier. It's very likely that you have the same problem suffered by people who attempt to use T-Mobile in the U.S. MMS simply will NOT work because the network is not compatible with the iPhone. If you want full functionality, you will have to switch to a supported carrier.

telus cant find any network problems and apple is difficult to deal with.please help 3 weeks with no phone and $70 a month not happy.

I have been having a similar problem for the last few days.Without warning the signal will just completely duck out leaving the device searching for several minutes before settling on a no signal message.
Sometimes restarting the device, toggling data and 3g settings or toggling Airplane Mode will set things right. However, a lot of the time I've been left without a working phone.
I don't believe this is a SIM issue, as I had to change my SIM only one month ago for another signal related problem. Again any help would be appreciated here as well.

"Software update can't check for updates because of a network problem" - help!

Recently, when I perform a software update check on the pulldown Apple menu, I get this error:
"Software update can't check for updates because of a network problem."
The only problem is that my network works just fine. I use the internet and get emails without any problem. But I can't figure how I can fix Software Update.
The only relevant updates have been for Glims and 1Password. Oh, and note the same problem trying to access the App Store; I just get a "Can't connect to the App Store" error.
Any hints?

I have to solve all my own problems.
The problem was due to Little Snitch. Once I upgraded from 2.4.0 to 2.4.2, my system works swimmingly again.
FIXED!

Troubleshoot installation problems in Photoshop Lightroom on Windows Vista

This document can help you to resolve system errors that occur while you use Adobe Photoshop Lightroom on Windows Vista. System errors can manifest in many different ways, including (but not limited to) the following:
A blank or flickering dialog box
A frozen cursor or screen
A blue screen
An unexpected restart
An error message such as:
"Setup is unable to load the installation script file."
"Unable to create a directory under C:\Windows\System. Please check write-access to the directory."
"Uninstalling: C:\Program Files\Adobe\Adobe Photoshop Lightroom refers to a location that is unavailable. It could be on a hard drive on this computer, or on a network. Check to make sure that the disk is properly inserted, or that you are connected to the Internet or your network, and then try again. If it still cannot be located, the information might have been moved to a different location."
Note: If you attempt to install Photoshop Lightroom to a drive that doesn't have the minimum required space available, the installation will fail. You must then completely reinstall to another location that has sufficient free space.
Many different factors can cause system errors, including conflicts among device drivers, applications, operating system settings, hardware, and corrupt elements in specific files. Although a system error may occur only when you work with Photoshop Lightroom, Photoshop Lightroom may not necessarily be the cause; it may be the only application that uses enough memory or processor cycles to expose the problem.
To benefit most from this document, perform the tasks in order. Keep track of the tasks that you perform and the results of each, including errors and other problems. Adobe Technical Support can use this information to better assist you if you need to call.
You must be logged on as an administrator to perform some of the procedures in this document.
Important: Some of the procedures in this document may initiate a User Access Control dialog that asks for your permission to continue. Read the details in the dialog to determine if you want to continue. If you choose to cancel the dialog, then you will not be able to continue with that troubleshooting step.
The steps in this document that refer to the Control Panel are in reference to the Classic view. For information on switching the Control Panel to the Classic view and many other common OS procedures, see Common Microsoft Windows Vista procedures (TechNote kb401275)
Some of these procedures require you to locate hidden files and hidden folders. Some procedures require you to locate files by their full file names, which include extensions (for example, example_filename.ini). By default, Windows Explorer doesn't show hidden files, hidden folders, and file name extensions that it recognizes.
To show hidden files, hidden folders, and all file name extensions in Windows Explorer:
In Windows Explorer, choose Organize > Folder And Search Options.
Click the View tab in the Folder Options dialog box.
In Advanced Settings, select Show Hidden Files And Folders.
Deselect Hide Extensions For Known File Types.
Click OK.
Note: The procedures in this document are based on the default interface of Windows Vista. If the interface is customized, some procedures may vary. For example, a commonly encountered difference is the navigation to Control Panel from the Start menu: You may navigate Start > Settings > Control Panel instead of Start > Control Panel. Additionally, the procedures in this document assume you are using the Classic View of the Control Panel: To view the Control Panel in the Classic View, click Switch To Classic View on the Control Panel navigation bar on the left side of the window.
Beginning troubleshooting
The tasks in this section can help you resolve the most common system errors. Before performing any of these tasks, back up all personal files (for example, Photoshop Lightroom files you created). Always restart the computer after a system error occurs to refresh system memory. Continuing to work without restarting the computer may compound the problem.
1.Make sure that the system meets the minimum requirements for PhotoshopLightroom.
Photoshop Lightroom may not run correctly on a system that doesn't meet the following requirements:
Intel Pentium 4 or equivalent processor
Microsoft Windows XP, Windows Vista, Windows 7
768 MB of RAM (1 GB recommended)
1 GB of available hard-disk space
CD-ROM drive
In addition to these requirements, a video card that supports 24-bit (16 million) or more colors, and a resolution of 1024 x 768 or higher, is recommended.
* Photoshop Lightroom 1.0 will install and run on Windows Vista but Adobe cannot guarantee the quality of the software experience until Adobe fully certifies Photoshop Lightroom for use on Windows Vista.
To check basic system information, such as processor speed and how much RAM is installed, choose Start > Control Panel > System.
2. Delete previously installed application files, especially if you had the public beta version of Photoshop Lightroom installed.
To delete files from a previous Adobe Photoshop Lightroom installation attempt:
Choose Start > Control Panels > Add or Remove Programs.
Select Adobe Photoshop Lightroom and choose to remove it.
Close the Add Or Remove Programs window and the Control Panel.
Open Windows Explorer.
If the Lightroom.exe file is still in the Program Files\Adobe\Adobe Photoshop Lightroom folder, delete it.
If the Lightroom Preferences.agprefs file is still in the Documents and Settings/[username]/Application Data/Adobe/Lightroom/Preferences folder, delete it.
Empty the Recycle Bin.
Try to reinstall. If you cannot, continue with the next two sections in this step:
Move all the folders under the Users/[username]/AppData/Roaming/Adobe/Lightroom folder into a new folder on the desktop; name the folder Lightroom Presets. These are the presets that were installed with the application and that you created.
Move all the folders under the Users/[username]/Pictures/Lightroom/Lightroom Previews.lrdata folder into a new folder on the desktop; name the folder Lightroom Previews. If you have a large number of images, you can move this folder back to its original location before you open Photoshop Lightroom, once it's installed. Or you can delete this folders to re-create it when Photoshop Lightroom opens. If there are further problems with Photoshop Lightroom after it's installed, it might be due to corruption in the previews, in which case you need to delete this folder and re-create it.
Try to reinstall.Important: Do not delete the Lightroom Database.lrdb file!
If there are further problems with Photoshop Lightroom after it's installed, these issues may be due to corruption in the preset files you created, in which case you need to remove them and re-create them, or test each preset individually.
Note: If you can reinstall, and if this is not the first time you opened Photoshop Lightroom, then Photoshop Lightroom will look for a library database file. If it does not find a library in the expected location, it will prompt you to create a new library, locate the library, or exit. Exit will close the dialog box, and Photoshop Lightroom will not open. Although you can tell Photoshop Lightroom to locate your library, it's best to put it back in the default location and then open the application.
If you can reinstall, close Photoshop Lightroom and then copy any presets you created from the Lightroom presets on the desktop back into the Users/[username]/AppData/Roaming/Adobe/Lightroom folder.
If you cannot reinstall, then move the Lightroom Database.lrdb file from the Users/[username]/Pictures/Lightroom folder into a new folder called Lightroom Database File and save this file on the desktop. This is your database, if you previously had Photoshop Lightroom installed.
Reinstall Photoshop Lightroom. If you cannot reinstall, continue with the next task in this document.
3. Log in as Administrator before installingPhotoshopLightroom.
In Windows Vista, you must be logged in with local (that is, machine) Administrator rights to install Photoshop Lightroom. If you don't have administrator rights, contact your system administrator for assistance.
4. Check the CD and CD-ROM drive.
Dust or dirt on a CD can interfere with an installation and prevent the CD-ROM drive from recognizing the CD. Examine the Photoshop Lightroom CD for dirt, dust, or fingerprints. Gently wipe the bottom of the CD from the center outward with a soft, lint-free cloth.
Verify that the CD-ROM drive can read other CDs. If it can't, examine the CD caddy or loading tray for dirt, and clean it with a lint-free cloth. If it still can't read other CDs, contact the CD-ROM drive manufacturer or the computer manufacturer.
5. Install current Windows service packs and other updates.
Updates to the Windows operating system improve its performance and compatibility with applications. You can obtain Windows service packs and other updates from the Microsoft website at www.windowsupdate.com. For assistance installing service packs and other updates, contact Microsoft technical support.
Important: Before you install a system update, check the system requirements for Photoshop Lightroom (and any third-party software or hardware you may use with Photoshop Lightroom ) to ensure compatibility. If the update isn't listed, then contact Adobe or the manufacturer of your third-party software or hardware.
6. InstallPhotoshopLightroomfrom the desktop and use the default installation folder.
Some system components such as device drivers and virus protection utilities can conflict with the Photoshop Lightroom installer and result in an incomplete or failed installation, or they can cause problems when you install to a folder or when you use a path to the default installation folder that contains a special character, such as #. To prevent these conflicts, install Photoshop Lightroom from the desktop, and use the default folder name and path.
If Photoshop Lightroom autoplay displays, click Cancel when you are requested to Select the Language.
Copy the Adobe Photoshop Lightroom folder from the Photoshop Lightroom CD-ROM to the desktop.
Open the Adobe Photoshop Lightroom folder on the desktop.
Double-click the Adobe Photoshop Lightroom.msi file, and follow the on-screen instructions.
7.Re-create thePhotoshopLightroompreferences file.
Re-create the Photoshop Lightroom preferences file to eliminate problems that a damaged preferences file might cause:
Quit Photoshop Lightroom.
Rename the Lightroom Preferences.agprefs file (for example, to Lightroom Preferences.old) in the Users/[username]/AppData/Roaming/Adobe/Lightroom/Preferences folder.
Start Photoshop Lightroom. Photoshop Lightroom creates a new preferences file.
If the problem continues, the preferences file isn't the cause. To restore custom settings, delete the new preferences file and restore the original name of the previous preferences file.
8.Install and run Photoshop Lightroom while no other applications are running.
Some applications may interfere with installing or running Photoshop Lightroom. Virus protection programs are meant to stop viruses from installing on your computer. Before installing or starting Photoshop Lightroom, disable other applications, including virus protection programs and startup items (items that start automatically with Windows).
To disable startup items and non Microsoft services:
Quit all applications.
Choose Start, type msconfig in the Search text box, and press Enter.
Write down all unselected items under the Startup and Services tabs.
Click the General tab, and choose Selective Startup.
Click the Startup tab and select Disable All.
Click the Services tab and select Hide All Microsoft Services.
Select Disable All then re-select FLEXnet Licensing Service. If you are unsure whether an item is essential, then leave it deselected (disabled).
Click Apply, and restart Windows for the changes to take effect.
Note: Upon restart, you'll be notified that the System Configuration utility has made changes to the way that Windows starts up. Click OK. When the System Configuration utility appears, click Cancel.
Right-click icons in the Notification Area and close or disable any startup items that are still active.
9. Install Photoshop Lightroom to a different hard disk after disabling startup items and installing from the hard disk.
Hard disk problems can prevent Photoshop Lightroom from installing correctly. By installing Photoshop Lightroom to a different physical hard disk, you can verify if the original hard disk is preventing installation. First, completely remove Photoshop Lightroom from the hard disk.
To install Photoshop Lightroom to a different hard disk after disabling startup items:
Follow the steps in task 8 above to disable startup items.
If Photoshop Lightroom autoplay displays, click Cancel when you are requested to Select the Language.
Copy the Adobe Photoshop Lightroom folder from the Photoshop Lightroom CD-ROM to the desktop.
Open the Adobe Photoshop Lightroom folder on the desktop.
Double-click the Adobe Photoshop Lightroom.msi file, and follow the on-screen instructions.
Click Change and select a different hard disk in the Change Current Destination Folder window. Click OK, and then follow the on-screen instructions.
Intermediate troubleshooting
If the tasks in the previous section don't solve the problem, try the following intermediate troubleshooting tasks.
10. Install and run Photoshop Lightroom in a new user account.
Create a new user account that has the same permissions as the account that you use when the problem occurs. If the problem doesn't recur, the original user account may be damaged. For instructions on creating a new user account, see To add a new user to the computer in Windows Help or contact your system administrator.
11. Optimize handling of temporary files by Windows Vista.
Windows and applications store working data in temporary (.tmp) files that they create on the hard disk. Excessive or outdated temporary files can interfere with performance of Windows or applications.
Delete temporary files by using the Disk Cleanup utility included with Windows or by using the following instructions. Make sure that at least 1 GB of free space is available on the hard disk to which temporary files are written. To start Disk Cleanup, choose Start > All Programs > Accessories > System Tools > Disk Cleanup. For information about Disk Cleanup, see Windows Help.
To manually delete temporary files:
Note: Windows deletes temporary files when Windows and applications close normally. However, when Windows or an application crashes, temporary files can accumulate on the hard disk. Windows may prevent you from deleting some temporary files as they may be in use. Delete as many temporary files as you possibly can, without deleting the files that are in use.
Quit all applications.
Choose Start and type %tmp% in the Search text box and press Enter.
Delete the contents of this folder.
Note the drive letter where this directory is located.
To ensure that at least 1 GB of free space is available on the hard disk to which temporary files are written:
Choose Start > My Computer.
Select the drive noted in step 4. Right click and select Properties.
Confirm the drive has at least 1 GB of free space.
12. Repair and defragment hard disks.
System errors can occur if hard disks contain damaged sectors or fragmented files. Repair and defragment hard disks, either by using the Error-checking tool and Disk Defragmenter utility included with Windows or by using a third-party disk utility. You should run such utilities on each hard disk or partition. More information about the Error-checking tool and Disk Defragmenter appears below; for more information about a third-party disk utility, refer to the documentation for the utility.
The Error-checking tool repairs bad sectors, lost allocation units and file fragments, cross-linked files, and invalid file names. To access the Error-checking tool, choose Start > Computer, right-click the desired hard disk, and choose Properties from the menu. In the Local Disk Properties dialog box, click the Tools tab, and then click Check Now in the Error-checking area.
Note: To prevent Disk Defragmenter from moving files to bad sectors of a disk, run the Error-checking tool before running Disk Defragmenter.
Disk Defragmenter rearranges the files and free space on your computer so that files are stored in contiguous units and free space is consolidated in one contiguous block. To access the Disk Defragmenter utility, choose Start > All Programs > Accessories > System Tools > Disk Defragmenter.
13. Scan the system for viruses.
Use current anti-virus software to check the system for viruses. Virus infections can damage software and cause system errors. For more information, see the documentation for the anti-virus software.
14. Try to install Photoshop Lightroomon a different computer.
Try to install Photoshop Lightroom on a different computer to determine if the problem is unique to your computer. If the problem is unique to your computer, contact the computer manufacturer; if the problem occurs on multiple computers, contact Adobe Technical Support.
Advanced Troubleshooting
If the tasks in the previous section don't resolve the problem, you may be able to resolve the problem by reinstalling Windows Vista and Photoshop Lightroom, reformatting your hard disk and reinstalling Windows Vista and Photoshop Lightroom, or by determining if hardware is conflicting with Photoshop Lightroom.
Disclaimer: Adobe doesn't support hardware and provides these procedures as a courtesy only. For further assistance, contact the hardware manufacturer or an authorized reseller. If you troubleshoot hardware problems yourself, you may void the warranty for your computer.
Note: Before you remove or rearrange hardware, turn off and disconnect power to the computer and any peripheral devices.
15. Log in using the built-in Administrator account.
The built-in Administrator account has a higher access level to the system than a normal local administrator account. By default the built-in Administrator account is disabled. For information about enabling and logging in to the built-in Administrator account, contact your system administrator. You can also refer to this support document on the Microsoft support website: http://support.microsoft.com/kb/926183/en-us?spid=11737&sid=73.
16. Reformat the hard disk, and reinstall only Windows Vista and Photoshop Lightroom.
Reformat the hard disk, and then install only Windows Vista and Photoshop Lightroom from the original installation media. Reformatting a disk erases all files it contains, so be sure to back up all personal files first. Also make sure that you have all application and system disks.
For instructions on performing a clean installation of Windows Vista, see document 918884, "How to install Windows Vista" on the Microsoft website at http://support.microsoft.com.
Note: Don't install additional software or hardware until you're sure that the problem is resolved. Don't back up the hard disk and restore Windows and Photoshop Lightroom instead of reinstalling them. If the problem is caused by an application or Windows, and either one is restored instead of reinstalled, the problem may recur.
After you reformat the hard disk and reinstall Windows and Photoshop Lightroom, try to re-create the problem:
If the problem no longer occurs, then install other applications one at a time and try to re-create the problem after each installation. If the problem occurs after an installation, then the recently installed application may be the cause.
If the problem occurs when only Windows and Photoshop Lightroom are installed, then the cause may be hardware-related, and you should contact the hardware manufacturer or an authorized reseller for assistance.
17. Check for problems with RAM modules.
Ensure that the RAM modules are installed properly and are not the cause of your problem. Do one or both of the following:
Change the order of the installed modules.
Remove all but the minimum number of modules needed to run Windows and [product], and test to see if the problem persists. If it does, replace the modules you removed and remove the others, testing again to see if the problem recurs. If it doesn't, then one or more of the removed modules are the cause. For assistance, contact the RAM manufacturer.

Please help! Major problems (performance and lock-ups) with brand new W520 with Intel 520 SSD

My company primarily uses HP machines but I've been a long time IBM (now Lenovo) fan so I recently had IT purchase me a new Lenovo W520 (product ID 42763LU).
Once the machine arrived I had them do the following:
Remove the 500GB HDD and replace it with an Intel 520 series 240GB SSD
Remove the optical drive and install the 500GB hard drive that came with the machine in the optical bay (with the bay adapter of course)
Format both drives and put a preconfigured windows 7 64-bit image on the SSD
A general summary of the system is the following:
Intel i7-2860QM CPU
8GB RAM
NVIDIA Quadro 1000M
Intel 520 240GB SSD (primary HDD) [SSDSC2CW240A3]
Hitachi 500GB HDD (optical bay) [HTS727550A9E365]
Intel Advanced-N 6205 network adapter
TouchChip Fingerprint Scanner
The machine was a few days delayed getting to me due to "hard drive driver issues" (that's what I was told). When I received the machine I immediately noticed that it was much slower than I expected (I have a custom built i5 HTPC at home running windows 7 on a Crucial SATA III SSD that I was comparing it to) and I was experiencing frequent hangs (ranging from 30 seconds to multiple minutes), super long boot times, general “slowness” at times, and occasional lock-ups. Since our "baseline" laptop here at work is the "equivalent" HP workstation my IT guys have been less than helpful in helping me to solve this issue. Being reasonably computer savvy I decided to try to try to fix the issue myself. I performed the following “troubleshooting” steps:
1. One of the first issues (errors) I noticed in the event viewer was errors related to the optical drive. Clearly the image they installed on the machine was not from a machine with the same hardware configuration. So, I decided to just wipe the machine and perform a fresh install of windows 7 from the disks (well, USB). After spending multiple days installing windows, performing updates, making sure all the drivers were current, and installing only the critical software I need, I was disappointed to realize that although I fixed the optical drive errors the machine was still slow, was hanging, and locking up regularly.
2. Removed the cover on the machine and removed/reinstalled the drive to verify it was secure.Everything looked good.
3. Verified the latest firmware is installed on all my Intel hardware. Everything seemed up to date.
4. I performed a number of troubleshooting steps like booting the machine with/without the battery, with/without the HDD in the optical bay, installed/removed from the docking station, etc. and none of these things helped (also a note – occasionally when running on the battery I was hearing a strange “buzz” or “static” sound coming from the area around the SSD).
5. Next I did some internet research and learned quite a few things. First, it sounds like others have had similar problems with this machine and/or SSD combo and there were quite a few options suggested to “fix” these issues. The general consensus for troubleshooting steps were:
5.1. Download and install the latest Intel chipset drivers and AHCI controller drivers (overwriting whatever windows installs during updates).This didn’t fix anything.
5.2. Turn off PCI express link state power management in the power manager. This didn’t fix anything.
5.3. Disable superfetch, prefetch, indexing, defragmentation, page file, system restore, and hibernate. A few of these were already disabled by windows so in those cases I just verified they were disabled in the services and application editor. These things may have slightly increased performance but did not fix the major hang/lockup issues I was having.
5.4. I followed online steps to edit the registry to disable the PCI link power management by adding ports, adding the required variables, and setting them all to 0. This did seem to have fixed the hangs and/or lock-ups but the machine is still much slower than I would expect (boot times are still pretty slow and it does “stutter” when I’m doing more than one thing at a time. Also a note here – I have the Intel SSD toolbox installed and I noticed that it was giving me a warning for DIPM not being optimized. I made the mistake of clicking “Tune!” and then started having the hang/lock-up issues again. I went back into the registry and sure enough the PCI link power management variables for ports 0 and 1 were set back to 1. I set them back to 0 and the hangs have gone away. I will not be “tuning” the DIPM through the Intel SSD toolbox again…
6. I also fixed a couple of other minor errors I was seeing in the event viewer by disabling benign services and/or making slight timeout modifications (I researched each issue on the internet to verify they were benign before I implemented any changes). These fixes didn't seem to do anything other than make some of the errors/warnings go away. So, the list of errors/warnings has become much smaller but I’m still getting the following (maybe an issue, maybe not?):
Event ID 37 for every processor saying that they are in a reduced performance state for xx seconds since the last report
Event ID 10002 - WLAN Extensibility Module has stopped
Event ID 4001 - WLAN AutoConfig service has successfully stopped
Event ID 27 – Intel® 82579LM Gigabit Network Connection link is disconnected
I suspect the WLAN errors have something to do with windows fighting with the Lenovo access connection tools?
7. Since the machine still seemed slow I downloaded the program AS SSD and checked the performance of the SSD. When I compared my performance numbers to the benchmark numbers I found onlineI was very surprised to discover that I’m getting about 50% of the performance that I should (values below are read/write).

One more note - it seems like my cooling fan is running at a high speed almost all of the time. This is probably one of my power settings (I think I have it set for max performance) but it's even doing this when there is no load (i.e. I'm using IE and just vieweing webpages - like right now).
So, I apologize for such a long post but I’ve spent countless hours researching and troubleshooting this problem and haven’t been able to figure out what the heck is wrong here. Am I missing something simple or do you guys think I have a SSD and/or problem with the machine itself? To say that any and all help would be greatly appreciated would be a massive understatement – I’m on the verge of pulling my hair out and I really need this machine working as quickly as possible!
Please let me know if you have any suggestions and/or need additional information. Thanks in advance for your help!

Lol gotcha about the drive as an option. I didn't go SSD with mine. Do you have the latest firmware on your drive? It is supposed to be v1.97. Just checking (ah and I see item 3 so guess so). Do you have the SSD drive toolbox software installed?

Seems some useful tools are in there. I can't say much beyond that with the drive. Oh. Why does your fan always run at high speed? Can you describe that? I mean, are we troubleshooting the right kind of issue? Is there anything else going on with your system? I saw about the reduced core speeds message. what are your system loads like? Anything causing high cpu utilization? Could be something other than the drive causing your low numbers and lockups.

Need help creating network of 1 Airport Extreme & 2 Airport Expresses!

Please somebody help me! I've literally been trying to get our home network to function for months now. I'm seriously about to cry if i can't make it work.
Here's the situation:
Our apartment is long and narrow and probably has lead paint, so our wifi, powered by a brand new Airport Extreme Base Station 802.11n router (named Igor) connected to a comcast modem doesn't reach the whole house. So we got 2 Airport Expresses to place throughout the apartment (named Sven and Svetlana) to help boost the signal.
First i tried to set up Igor to 'Create a wireless network" with the option 'allow this network to be extended' and the connection sharing set to 'Share a public IP' and i set up Sven and Svetlana to 'extend a wireless network' and the connection sharing was set to 'share a public IP'. Everything else was automatic or default pretty much. I got it to work but the connection was really weak and dropped out a lot.
Then i tried setting up a WDS network. no luck there either. so i went to the apple store and they told me i had to hard wire them all together using ethernet cables (roaming network i guess) to compensate for the ****** network acoustics in our place.
So...i ran 1 ethernet cable from Igor down the hall to Svetlana and another from Igor further down the hall to Sven. I set up all 3 to 'create a wireless network' and gave them all the same network name and password. i left the 'allow this network to be extended' option unchecked on all 3 and put them all in bridge mode and automatic settings for the radio mode and channel selection. After about 50 restarts i finally got it to work. Things seemed great for a minute until i realized that my laptop was the only one in the house that could connect to the internet. When i tried to troubleshoot the problem using network diagnostics and restarts, i eventually got my roommate's laptop to work but then mine stopped working.
i've tried changing Igor's connection setting to share a public IP address and leaving Sven and Svetlana's in bridge mode. I've tried changing the 'configure IPv4' setting from 'using DHCP' to 'manual' and entering in identical info for all 3 in the TCP/IP section.
no matter what i do i still have no idea how to make this work for multiple devices in our apartment. I really don't understand that much about networking but i am great at following directions. Please please please please help me! I'm desperate.
thank you in advance for your help!

In a "roaming" network, the router connected to the Internet modem should NOT be in bridge mode. In this case that would be your 802.11n AirPort Extreme Base Station (AEBSn). That is because you want it to provide both NAT & DHCP services to both AirPort Express Base Stations and the network clients.
