System Slows Down and Freezes a LOT - Memory? Swap? Hard Drive? AV?
I have a 2.4 GHz 24" dual core iMac (identifier: 7,1). It worked fine for a good while and lately I've been having problems that seem to be getting worse (sometimes it seems to get better, then worse again). I have 4 GB of memory and I'm waiting for more RAM to upgrade it to 6 GB, since I hear that's the max anyone's run successfully in this model.
I've often had a number of programs running at once. Usually I have Firefox, Apple Mail, the KDE's Konsole and Kate (from MacPorts), Calendar, Stickies, MacIago, and Pysol running. (Yes, it helps to have a few games up for breaks when I'm working.) I know that's a lot, but for well over a year, I was working with that setup without problems, without getting stuck for long times with the pinwheel of death or anything like that.
I'm not exactly sure when it started, but now I have times where I will do something and the program will freeze and I get the pinwheel of death. I wait and after 30-60 seconds I can do something, but sometimes I still get hesitations and a start-freeze&stop-go mode for a bit. Sometimes this freezes the whole computer for up to 30-60 seconds and I can't even check another space with Command-Arrow.
I've been trying to backtrack to see if I could figure out what is causing this. Sometimes killing Firefox helps, so I switched to Chrome and watched for usage on Activity Monitor and Chrome uses FAR less CPU time. I have FlashBlock and AdBlocker Plus on Chrome (had it on Firefox, and before that, used NoScript for blocking). But I've seen this happen even without a browser open.
I suspect this could be an issue with swap, since recently I was watching and saw spikes in disk usage around these times, but I'm not sure of the correlation yet. Sometimes it seems like whenever I switch to a different program, whenever I use a new feature, I have to wait (as if it's loading library code or something).
Again, this is a recent issue.
I've upgraded from 10.6.5 to 10.6.6, so I don't know if that could effect this.
I've also started using the free version of Sophos Anti-Virus (which is apparently impossible to quit once it's running) and thought it might be doing scans.
What's also puzzled me is seeing that, with 4 GB of memory, Activity Monitor continually shows 1 GB free, but still indicates 2 GB swap files. So is there a reason 25% of my RAM is not being used?
I've also checked and found my drive to be heavily fragmented. I bought iDefrag, but it can't defrag it because there seem to be some bad blocks. Rather than mark them as bad every time it hits that spot, it just tells me it can't access that part of the drive.
My guess is that OS X, for some reason, leaves a set amount of memory free to use for various reasons and that, due to fragmentation, what was once an easy task of accessing something in a swap file is now time-consuming.
Is that on target? What else could be causing this problem? This is beginning to make my iMac unusable. If it's just swap file issues and defrag problems, I'm thinking of cloning my internal 320 GB drive to a 1 TB drive and replacing the original, then running iDefrag for good measure and continuing from there. (It seems like in OS X finding bad blocks is difficult, from what I've seen.)
What can I do and does anyone have any idea what the problem is? I'll be glad to give more details if that helps, but I've tried to include as much as I can already.
Thanks for any ideas or help.
Considering how I've solved this, I'm pretty much shocked that nobody had any answers for this.
I upgraded my drive from the standard 320 GB drive (which had about 79 GB free on it). I used Carbon Copy Clone to copy my system drive to a 1 TB drive, then swapped out the 320 GB for the 1 TB. When I booted it up and started working, I noticed it was back to the way things used to be: I could go from one program to another to another with NO problem at all. No pinwheels of death and I even added a few more more running programs and still had no issue.
I have no idea why, but before, even when there was a 2 GB swap file, 1 GB (out of 4 GB) of RAM was always unused. I don't know if the OS looks at what it can access and figures read/write times and uses that to figure out how much memory it can effectively handle or what, but now I'm using almost all of my 4 GB of RAM and the swap file is smaller than it was.
So upgrading to a larger drive made a HUGE difference. I'm willing to bet that defragging the old one would have made a difference as well, but there were problems with some files and iDefrag could not read them, which also makes me suspect that drive was on its last legs and close to failure. (That and bad sectors could also have slowed down swap, along with fragmentation issues.)
The solution was a bigger drive, but I suspect defragging the old drive might have helped (if it weren't for possible bad blocks). I know deleting files from the old drive did not help too much.

How do I fix a Safari application that slows down and freezes everything?
Apple called last fall and said my particular Mac had a hard disk problem and they replaced it at the Apple store in late January 2013. I backed up the information on an external harddrive and used Time Machine before to transfer all the information to the new drive. Everything worked well and I finally put on Mountain Lion at 10.8.4. I also have Carbonite as a backup and it apparently was not enabled when I transferred the files until early May. In early May I had not used my iMac for about a month and when I started it I found about 40 named file folders on the Desktop that were empty. Some of those had named items in them but when I clicked on them they would dissappear. The actual files did exist and were not effected when I dumped the apparent alias folders. Safari started and would be ok at first but if I went away for an hour it would slow down. I took it in to the Genius Bar at Apple and they ran some tests and got rid of MacKeeper which they felt was causing the problem. I got my Mac back home and it still started slow but worked well at first and then started going slow. If I opened Word it would also start working at a slower speed. I needed to force quit Safari and the Word progran in order to quit or restart the Mac. I got an appointment for the next day and they ran all sorts of tests and the hard drive was working normally. They tried tweeking different areas and sent me home again. When I started working again it did the same thing, I would start out fine and eventually slow down and needed to be force quit to get out of it. A message came up indicating my MasOSX startup disk had no more space available for applications memory. I took it in a third time and the Genius went to the Activity Monitor and the Safari PID was 221 and %CPU 107, Threads 21 Real Mem 2.73 GB, Virtual Mem 22.00 Kind, Intel (64). I had no idea what that meant. I went home again and it still ran slow and couldn't run the programs for any length of time before it ran slow and affected the other programs so they would only quit if I used Force quit. I took it in for the forth time an they decided to keep it overnight. They ran ASD first to rule out memory. They noticed during the appointment the computer was slow to perform normal tasks such as showing boot options, booting into user, bootingto external user. If the ASD passed then they would perform erase and install and only restore users and application files from backup drive. They did this on Wed and Thur. night and I took it home Friday night, June 14 and it still has the same problem. Typing this message right now means typing and waiting for the words to appear.
Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -f -a TextEdit
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open. Post the contents of that window, if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; sudo defaults read com.apple.loginwindow LoginHook; } | open -f -a TextEdit
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}' | open -f -a TextEdit
Step 4
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null | open -f -a TextEdit
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of every login item' | open -f -a TextEdit
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal. -
[Solved]Computer slow down and freeze during data transfer syncing
Hello,
Everytime I make a data transfer, my computer slow down, and sometimes freeze during a few seconds, work for a fraction of seconds and freeze again. I don"t understand why.
As an example, here is a bench of files i transfered during a syncing with Grsync
It took about 12h to sync 64Gb.
I've read a lot of topics talking about this problem but nothing works. I tried to switch off the SWAP and setting the vm.dirty_ratio and vm.background_dirty_ratio but nothing works.
I'm making the trasfer between two Western Digital USB 2.0 external hard drive in NTFS.
Does anyone know how to fix this?
Thanks in advance
Last edited by Neldar (2015-03-04 15:54:29)It seems it was beacause one of my external hard drive was about to die. I performed the same operation with 2 Western Digital external hard drive 1To USB3 and it works perfectly.

System slows down and power up problems
Hi,
I have a Rev A G5 iMac (1.8Ghz, 1.5GB Ram) which has been working fine since purchased in 05.
Over the 5-6 weeks we have been experiencing system slow downs. All applications will start running slower and slower (not heavy usage, mail, safari, BT client running and occasionally iMovie) to the point have to restart.
But when restarting the iMac it will not power up, it starts and 1 sec later shuts down. So I leave for a while and try again, and it will work although the fan is extremely loud.
I was having to restart every few days but now its to the point of a few times a day.
have run hardware test and all is fine...and as do not have applecare want to see if can do anything myself before taking in for a quote/repair.
Oh another thing, the superdrive will not burn via finder anymore only via toast...that started at the same time as the rest.
many thanks
ZaraHi Zara - have you tried opening the back and vacuuming out several years accumulation of dust? You can also try resetting the PRAM and the SMU and see if that helps.
Please post back,

Combo 10.7.4 Update slowing down and freezing applications
After updating from Combo Mac OS X 10.7.3 to Combo Mac OS X 10.7.4, my third party applications slow to a crawl and freeze on a rotating basis.
Affected applications:
- BOINC with which I do volunteer medical research (3 CPUs used 100% of the time);
- aMule 2.3.1 to download files;
- Mozilla Firefox 12.0 to browse the internet.
I tried to reduce the CPU usage of BOINC (3 CPUs used 80% of the time instead of 100%) to no avail.
I re-installed with some difficulty Mac OS X 10.7.1 from the copy I bought on the Mac App Store to preserve the work I had done on my iMac since the last TimeMachine back-up, but did not improve performance, possibly because I ended up with a mixed system of Mac OS X 10.7.4 components surviving the Mac OS X 10.7.1 re-install.
I am currently performing a TimeMachine re-install of my previous system (Combo Mac OS X 10.7.3) which will take almost a full day and erase my Macintosh HD to copy the TimeMachine content.
When reading posts on AppleInsider.com and TonyMac x86 blog @ http://tonymacx86.blogspot.ca, I came up with at least 3 different explanations:
- The Mac OS X 10.7.4 System takes up all the RAM memory and gives back unused, free memory only slowly, so that third party applications (and Apple applications such as the Finder and Force Quit) don't have enough free memory and freeze on an alternate basis, although my Core i5 quad-core iMac has 12 GB of installed RAM recognized by Mac OS X;
- Apple has changed kext files in anticipation of the upcoming Mac OS X 10.8 Mountain Lion and accidently changed the CPU multiplier so that the CPU is artificially limited to 1.6 GHz (instead of a quad-core 2.66 GHz);
- Apple has changed the /Extra/org.chameleon.Boot.plist file and the following lines of the booting sequence:
<key>GeneratePStates</key>
<string>Yes</string>
should be replaced by using TextEdit to copy the following lines:
<key>DropSSDT</key>
<string>Yes</string>
For more info, see:
http://www.tonymacx86.com/viewtopic.php?f=168&t=59889
I'm just an average user with no programming skills. I don't feel comfortable with doing undocumented tweaks when I don't really understand what I am doing. On this one, I sure hope that Apple engineers are investigating the issue to come up with a fix.
In the mean time, I am using TimeMachine to re-install my previous system (Combo Mac OS X 10.7.3) which will take almost a full day. I have been deprived of my iMac for 3 days and that's all the time that I can spend on a malfunctioning Combo Mac OS X 10.7.4 Update.
quad-core Core i5-750 @ 2.66 GHz
12 GB SO-DIMM RAM
2 TB hard drive with 100 GB of free spaceFinal report:
I hope that my experience will help others who added their comments to this thread and anyone else who has problems updating Mac OS X.
Here's the solution to my problems:
1- I backed up the contents of my iMac using TimeMachine (before any attempt to install a major system update) so that I would always have a copy of my Mac running smoothly under Mac OS X 10.7.3;
2- I used Geekbench to measure the performance of my iMac running Mac OS X 10.7.3 and achieved a score of 7622;
3- Using Google and browsing through Apple Support Communities, I realized that Mac users weren't up in arms over the Mac OS X 10.7.4 Update, instead I was confronted with a number of users reporting various issues, none of which was similar to what my iMac experienced, meaning that my experience was unique, exceptional;
4- Starting the iMac through a self-made Mac OS X 10.7.1 booting DVD (I didn't make a Mac OS X 10.7 Lion USB thumb drive), I used my TimeMachine backup to erase the contents of the iMac and replace it with the copy of the backed up iMac running Mac OS X 10.7.3 (before the Mac OS X 10.7.4 Update);
5- Once everything was stable and running well, after repairing the Macintosh HD and then, repairing permissions with the Apple Disk Utility, I did what most Mac users do, i.e. use the Software Update command under the Apple menu to check if there were any available update for my iMac running Mac OS X 10.7.3;
6- Software Update offered me a 729 MB Mac OS X 10.7.4 Update which is bigger than the 692 MB Mac OS X 10.7.4 (Client) Delta Update being offered on Apple Support Downloads;
7- I downloaded and installed the 729 MB Mac OS X 10.7.4 Update offered through Software Update which, presumably, contained additional software which is specific to the iMac model and year that I use;
8- After making a Safe Boot as described by Apple @ http://support.apple.com/kb/HT1455, repairing the Macintosh HD and then, repairing permissions with the Apple Disk Utility, and giving the iMac 2 more days to defragment on its own the hard disk, I am pleased to report that my iMac achieved a higher score of 7663 on GeekBench, showing that everything is back to normal and that my iMac runs even better with the Mac OS X 10.7.4 Update.
Hope this helps anyone reading this post. Good luck.

Ios 8 on i phone 5 slow response and freeze a lot
I've updated my i phone 5 to ios 8.0.2 but now it's so slow , freeze a lot and most of the apps crash i turned on my location service nothing changes
As razmee209 said, you can use iTunes to install photos on your phone from wherever you have them stored. Where did you copy them to? Are you saying you selected them on you phone and just hit "copy"? That would only copy one at a time to the "clipboard" so that you can paste it somewhere else. As you copy each one, the previous one is deleted from the clipboard. This is not a storage area. Did you back them up on your computer or in iCloud?

I am running Mac OS X Mountain Lion with the newest updates. Since 4 Weeks I am receiving error messages like this one:
WindowServer[112]: CGXDisableUpdate: UI updates were forcibly disabled by application "Chrome" for over 1.00 seconds. Server has re-enabled them.
I used EtreCheck and see some failures.
Could anybody help me, how to fix the following failures to speed-up my Mac OS again. ;-) I uninstalled Bluestacks AppPlayer and don't find the following plists.
Many thanks...

Back up all data to at least two different storage devices, if you haven't already done so. The backups can be made with Time Machine or with a mirroring tool such as Carbon Copy Cloner. Preferably both. You must be certain that you can restore everything to the state it's in now.
Note that if you're running in safe mode, you can't connect to a Time Capsule or other network volume. You'll have to back up to a locally-attached hard drive.
Boot into Recovery, launch Disk Utility, and erase the startup volume with the default options. This operation will destroy all data on the volume, so you had be better be sure of your backups.
Quit Disk Utility and install OS X. If you upgraded from an older version of OS X, you'll need the Apple ID and password that you used to purchase the upgrade from the App Store, so make a note of those before you begin.
When you reboot, you'll be prompted to go through the initial setup process. That’s when you transfer the data from one of your backups. For a walkthrough, see here.
Transfer only "Users" and "Settings" – not "Applications" or "Other files." Don't transfer the Guest account, if it was enabled on the old system.
After that, run Software Update.
If you still have the problem, take the machine to an Apple Store or other authorized service provider for hardware testing.
If the problem is resolved after the clean installation, reinstall your third-party software selectively. I can only suggest general guidelines. Self-contained applications that install into the Applications folder by drag-and-drop or download from the App Store are usually safe. Anything that comes packaged as an installer or that prompts for an administrator password is suspect, and you must test thoroughly after reinstalling each such item to make sure you haven't restored the problem.
Before installing any software, ask yourself the question, "Am I sure I know how to uninstall it without having to start this process all over again?" If the answer is "no," stop.
Never install any third-party software unless you know how to uninstall it. -
IPhoto crashing, slowing down and freezing up.
iPhoto chashed 4 times with me while doing the same task, creating a Photo Book.
Apart from that, it would slow down while editing a pic within the book creation interactive app, and would show the little pie, like it was loading or reading something, once doing that it has frozen, and whether it would recognize it crashed, or I would have to force quit.
FYI: - I only have 60 pics tops in iPhoto
- iPhoto is the latest version and it is updated
- along with the computer, it is brand new, nt more than a week old.
- it did also happen the first time to loose all the contents on the photo book, it crashed and asked to report or restart iPhoto.
Thanks for whoever can help me....Over the weekend I did the following:
1) Backed up my entire computer
2) Booted from the Mac OS X install DVD, launched Disk Utility, and erased my entire hard drive
3) Installed Mac OS X from scratch (version 10.4.7 was on the DVD) along with the base applications
4) After the install, I logged in and ran software update until iLife '06 was patched up, and 10.4.10 was loaded with all security updates
5) Inserted iLife '08 disk -- installed iPhoto '08
6) Launched iPhoto '08, made sure it was working fine (with a library of NO Photos)
7) Restored a copy of my iPhoto library to my hard drive
8) Launched iPhoto '08 again (made sure it was STILL version 7.0.1), and saw that my book was there along with all of my photos, etc...
9) Attempted to purchase my book. And the result was: On page 28 of 32 -- CRASH of the entire computer.
Here's a picture of it: http://www.kmcode.com/misc/errors/iphoto08crash.jpg
Sorry, had to take a quick snapshot with the digital camera. It doesn't do well up close and such...
Anyways. This bug exists regardless of which version of iPhoto '08 you are running. I'm very peeved about it, for I spent an entire weekend backing up my computer, hunting down the original disks, reinstalling Mac OS X from scratch, downloading software updates -- and it still crashes the entire computer when I try to assemble a book or generate a PDF of the book. I am at wits end with this. And as stated before -- I can in fact create a book with autoflow with the exact same photographs, and it will send to PDF just fine. You just can't adjust any of the photo attributes!
Also, I'll note that my iLife '08 disk comes with version 7.0.1 on it from the factory. I can't seem to get to version 7.0 to see if it will work. -
Does shutting down and starting up wear out the hard drive faster?
does anyone know if shutting down and starting up the imac repeatedly wear out the hard drive faster? I had heard that repeated shutting down and starting up of the hard drive will wear out the hard drive faster. If this is true, is it better to put the imac to sleep and shut down only when you absolutely have to or when you will be gone for a while? (e.g., going on vacation or when moving the imac). The imac manual suggests that if you are going to use the imac within a few days to put it to sleep and shut it down if you are not going to use it for a few days. Is this advice just to save you time since you don't have to reboot or will this help prolong the life of the hard drive? Of course, keeping the imac on all the time might waste energy (not sure if sleep mode saves energy). But since I use the imac practically everyday it may make sense to put it to sleep, especially if this will prolong the life of the hard drive. thanks
Good Morning,
In my experience there shouldn't be any unnecessary wear and tear on your hard drive from shutting down your computer unless you are doing an EXTREME amount of startup/shutdown cycles.
The average user should not put enough strain on the drive to even be noticed from normal startup/shutdown cycles.
Hope this helps!

Leopard slows down and freezes - please help
I'm running Leopard on a Macbook and I have had startup problems and slowdowns in general a couple of days now.
When I start up the machine I get the apple logo, the spinning circle and then the blue screen for about 2-3 minutes before I get my Leopard wallpaper. It then takes another 3-4 minutes before the dock and icons load up and usually a couple of minutes before I can actually access the desktop.
The whole startup usually took me less than 2 minutes total and is now as you can see a much longer process.
Once in Leopard applications take much longer to load than usual and often freeze or stop responding. I get the colored spinning disc a lot and it seems like Leopard is using a lot of time loading up even simple apps like iCal and Mail.
I'm not sure but it seems like Finder is the problem. I have tried restarting Finder a couple of times and this always gives me the gray screen telling me to restart Leopard by holding the power button.
I have no idea why this has happened, I haven't installed any big apps or used up a lot of the HD space. I still have approx 85GB on my HD so that shouldn't be the problem.
I have of course tried the basic troubleshooting such as restarting and verifying/repairing disk permissions in Disk Utility so I don't know what else to do.
Any suggestions, tips, or ideas are truly appreciated. I really want my old Mac back, the waiting is driving me nuts.
Thanks
Dave

Did Verify report any errors? Did you try starting up from the Leopard installation disk and running Disk Utility from the Installer's Utilities menu, then running Repair Disk?
Verify didn't report any errors so that didn't really help.
I have just popped in my Leopard disk but there doesn't seem to be a menu for "utilities". My options are "Install Mac OS X", "Optional installs" (which doesn't have a Repair Disk option", and "Instructions".
Did your MacBook come with Leopard, or did you install the upgrade over your Tiger system?
The machine came with Tiger so I bought Leopard seperately, formatted the HD and did a clean install. But this was back when Leopard came out and I haven't had any problems with the OS until now. -

this occurs randomly ............yes I m Using Auto desk Inventor 2014 pro, and problem starts When I instal this software after Every RESET, should I re-install the whole Software or Auto-Desk 360 only, but latest version Of inventor is
2015 and It might not be compaitable to my System. -
When I open my browser, it takes 3-5 minutes to fully open. When I get to a website, randomly the tab will say 'Connecting' and slow down and take 10-15 minutes to function or freeze completely. This almost always happens on sites that require Flash Player use. I have uninstalled and reinstalled my Flash several times. I've added memory, as someone suggested it was a memory issue. It's so frustrating, please help!
A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process.

T61 Wlan freeze, System slow down
Hi,
everytime i connect via wlan at my university my wlan freezes after 20-50 minutes(Wlan -LED turns off, AC do not react, hole fu**in windows gets slow). this suxx, cause when i try to search something on e.g wiki i have to reboot first. this makes me angry cause i paid 1500 € for a piece oh crap ! other students with some lame toshiba or other low-prize laptops don't have this problem. i tried everything: deinstalling/installing Access Connection, using windows wlan manager, 3 time lenovo windows installation, daylong research on forums, but nothing works.
since 2 or 3 days i got this problem also at home. can somebody help me ?
Wlan adapter: intel 3945abgWe have two laptops and both have the same issues.
I bought external WLAN cards (to replace internal slow ones) and first it helped but after two days the T40 refused again to get any wlan connection. R40 works but after 20 minutes the networks slows down and makes it impossible to use any network resource. T40 works with cable, but in R40 network connection is also dead.
I have reinstalled, resetted and tried everything I could imagine (20 years of IT experience), but nothing helps, so the next thing is to buy new laptops and they are not T or R series if there is no answer how this issue could be fixed.
Somehow it seems that there is a virus that prevents using network, but I am using many antivirus products and the laptops are clean for known viruses. The most strange thing is that T40 will freeze also mobile internet connection and a new connection can be done only after rebooting the phone, so there is really something strange going on.
I have also a MacBook Pro and it has a superfast and reliable wlan, but I use it only to one project, so I can not use it daily. -
Fire fox crashes and freezes if i use it too much (kind of a good thing). For example if i use stumble fire fox will start to slow down then freeze completely. I am using windows XP pro and a pretty decent computer. All software is up to date and i do no have a virus. I have even tried to disable my add-ons and plug-ins but it did not make a difference. Does anyone have a solution or should i just switch to chrome?

Do the issues still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode -
