Windows Vista = very slow wireless network

I have a brand new Lenovo ThinkPad Z61p. A great machine, great performance. But Vista seems to get in its way.
The first thing I did, was to re-install Windows Vista to get a clean machine, without alle the junk that comes with it. At work, the wireless network worked just fine - but when I came home, it was so slow. I mean REALLY slow. If I turned the wireless network card off, and plugged in a cable, I was flying on the Internet. But for the wireless adapter, even a page like msdn.microsoft.com could take 3-4 minutes just to load.
I thought the issue was the drivers for the wireless network adapter, but later, in my desperate attempt to solve the problem, I removed a Windows feature called Windows DFS Replication service, which solved my problem.
This was 4 weeks ago - and now the problem has returned. I've been reading a lot of forum posts around the web. I've uninstalled some other features, disabled IPv6, disabled Vista Auto-tuning ( i did that 4 weeks ago as well)...
Nothing is working. I've also changed the default Network authentication mode, I've updated the drivers for the Intel Pro Wireless 3945abg, changed the wireless mode and a lot of things. Nothing is working.
Does anyone in here have the same issues, or does anyone know what is wrong?

I picked up a new IBM ThinkPad T60P (Wide) running Vista Business, and I am experiencing the same problems with an extremely slow wireless connection. I get the same slow performance on the wireless network in my office as in my home.
The second I disable the wireless and plug in the cable directly to the router (ZyXeL) everything runs perfectly. I also tested connecting an Apple AirPort to the router (via cable) and connected directly to the AirPort as an access point instead of connecting to my normal wireless network, and then everything was working just fine for some reason (almost as fast as when I connect directly to the router via cable)!
The really weird thing is that I get really quick download rates on at least one website (www.dailyrush.dk) where I can download files at 1.1 MB/s (I should have 15 mbit downstream). The web pages of that website still load pretty slow though when I'm browsing. Most other websites that I have tested load insanely slowly, both when I'm just browsing the pages and when I'm downloading files. For example a 1024 x 695 pixel JPG on Flickr.com might take several minutes to load, or simply time out. The Google front page sometimes takes 15 seconds to load.
I have my old laptop parked right besides the new one, both connected to the same router on wireless, and the old laptop (IBM ThinkPad T41 running XP) performs fine - downloading anywhere from 10 to 100 times faster!
It also takes forever to connect to VPN, perhaps 15 or 20 seconds on the Vista laptop and no more than 2 seconds on the XP machine.
When I ping www.google.com in a command prompt I get some packet loss (between 25 and 100 %) but reasonable ping times averaging about 45ms which is the same as on my old laptop.
I have tried pretty much everything:
Disabling Windows Firewall
Disabling TCP/IP v6 and those other entries in the wireless adapter configuration that are new in Vista
Disabling security on the router entirely
Changing security on the router to WPA and WPA2
Changing the channel on the router (tried several available channels)
Switching between 802.11 a/b/g modes on the router
Booting up in safe mode (heard that worked for someone with a similar problem)
Updating the wireless adapter driver to the newest version
Installing all available updates from Windows Update
Moving my laptop really close to the router (duh)
Uninstalling MacAfee
Uninstalling Bullguard
Uninstalling a bunch of pre-installed IBM stuff
I have come across several threads online where people have had the exact same problem and solved it by uninstalling the pre-installed MacAfee software. My laptop came with MacAfee too but I uninstalled it right away and installed Bullguard instead. When I noticed the connection problems I uninstalled Bullguard too, but little did it help.
I really hope that someone can help me out here ... I'm kind of running out of ideas :-( Thanks in advance.
Cheers,
Stefan

Slow wireless network since Vision upgrade

I was "upgraded" to the new look vision on Wednesday the 5th of June. The next day I noticed that my iPhone 5 and Nexus 7 tablet was getting a very slow wireless connection. I reset the hub but the problem still persisted even though it was showing a full signal.
I then changed from BBC1HD to the BBC1 freeview and the phone and tablet sprung to life. I changed back to the HD channel and the wireless crawled to a stop. I can now replicate this everytime.
My BTHOMEHUB3 is connected directly to the Vision box via a 2m ethernet cable (yes I have tried replacing the cable without success and have tried connecting to different hub ports). Speedtest indicates a download speed of 76mbps download and 15 mbps upload. When I switch to the HD channels the download speed drops to 58mbps with no change to the upload speed, so I dont think the speed is the problem.
I am hoping that someone here has experience with this problem as it has me baffled. The call entre suggests I leave the vision box and router switched off for an hour before reconnecting and to call back if that doesn't sort the problem (it didn't) I am reluctant to call back because the next person I speak to will just have me going through the same crib sheet again.
Mant thanks.

Quite seriously, the servers themself are really the least likely
culprit here. Everything points to a much more wdespread problem
affecting pretty much everything on the network. That could be the
network itself, or some machine that has crapped out and overloads the
net, something like that. NW65SP8 / BM3.9 is extremely stable, including
all included drivers.

Windows XP laptop sees wireless network but won't connect

I set up a wireless network on my airport extreme using my MacBook. The McBook runs great on the wireless network. My old Dell laptop running Windows XP sees the wireless network I created (with full signal strength) but every time I hit "connect" I get the following error message, "Windows is unable to connect to the selected network. The network may no longer be in range. Please refresh the list of available networks, and try to connect again." When I referesh the list, the wireless network is still there, and i still cannot connect, getting the same error message.
Any suggestions?

Hello apetera. Welcome to the Apple Discussions!
Per chance are you using WEP for your wireless encryption?
If so, one of the problems with WEP is that the actual standard relies on a 10 character HEX key for 40bit WEP and a 26 character HEX key for 128bit WEP.
In order to make things easier, vendors use certain algorithms to convert simple alphanumeric passwords (or passphrases) into HEX keys, thus enabling the use of simple easy to remember WEP password rather than lengthy HEX keys. The problem is that different vendors use different algorithms to generate the HEX key and therefore a ASCII password on an AEBS will be hashed differently on a non-Apple client and vice versa.

Windows phone security on wireless networks

I am a post-doc at large medical center, and requested access to our secure wireless network due to the nature of my work. I was told by our IT support desk analysts that Windows
Phone is not supported at our medical center (at all), because Windows phones are "too insecure to put on our network." Because of this, I either have to get rid of my brand new Windows Phone to get an android or I will never be allowed to have access
to the secure Wi-Fi as necessary for my job. Any thoughts or suggestions? This seems to be a serious limitation of Windows Phone.

Your support desk is outright lying to you. There is no issue with Windows Phone security on wireless networks, they just don't want to support your phone. It might be possible that Windows Phone doesn't support the particular kind of wireless encryption
that your org uses, but I'm pretty sure that was all solved with Windows Phone 8.
In fact, Windows Phone is more secure in some ways because unlike iOS and Android, you cannot override security certificate problems.

Windows 7 very slow logon, Waiting for the User Profile Service, winlogon event 6006

Hello,
Every so often one of our Windows 7 clients which is not normally having any delay at logon will take a very long time to login. This may be 10 or 20 minutes or up to an hour in some cases.
Typically the event log will contain entries like
The winlogon notification subscriber <Profiles> took 572 second(s) to handle the notification event (Logon).
There is no further information available from Event Log Online Help, nor any additional detail as to why the logon event was so slow. During the delay the user will just see "Waiting for the User Profile Service" on their screen.
We first started seeing this problem with Windows Vista and if anything the situation has not improved since then. It has never happened with any of our Windows XP users.
We are currently planning a migration of computers to Windows 7 but stuff like this which has not been resolved in Windows over a 2 year period will stall that migration. The least improvement is to increase the event notification to give a lot more
information on why the user profile processing has stalled.

Hi,
When did the issue begin to occur? Did it occur after installing certain application or applying certain policy?
To troubleshoot the issue, please perform the following step.
1. Restart the machine in Safe Mode with Networking to check whether the system can login quicker.
2. Type “gpedit.msc” in Search box and press Enter. Navigate to the following location:
Computer Configuration->Administrative Templates->System->Logon
Please double click “Always wait for the network at computer startup and logon” policy and disable it.
3. Perform a
Clean Boot to check the result.
Thanks,

Windows Can't Detect Wireless Network

I have a windows xp laptop which can't detect the wireless network i've created with airport express- but it seems to be able to detect other networks around the area.
My two other machines (one macbook and the other xp) does pick up the network.
It seems like everything is working fine. 2/3 computers can pick up the signal, but just one of the computers can't! And i've repaired and reinstalled the driver for the wireless card, but it just won't detect the airport express signal!

That link does not help.
The network card on my windows xp machine works fine. It can detect other networks in the building and works at other WiFi spots.
I think its something to do with somthing in XP and Vista that is preventing it from detecting Airport Express' signal.
I've increased signal robustness- still doesn't work.
I've removed the password- still doesn't work (obviously not a security problem).
I've updated the software- still doesn't work.
I'm very confused as my XP machine did detect it initially and connected to it successfully earlier this year, but it doesn't anymore.
It seems like the network can be detected by some windows machine but not others???

Best connection for Windows Vista Desktop to Apple Network

I have a Windows Vista/Dell Desktop that I've hooked into my Wireless Network which is all Apple products. The Wireless card in the Dell is a D-link, but I have a constant problem with it dropping out when connected to my Apple TV. I'm wondering if I can hook an Airport Express directly into the Dell by an Ethernet cable, effectively using it as my Wireless Network "card" for the Dell. That would make all my Network components Apple products which I think would improve the reliability. Does my plan make sense??

Yes, this will work fine if you have a good wireless signal at the location for the Express. You would configure the Express to "join" the wireless network created by your Apple base station. Make sure that you put a check mark in the box next to "allow ethernet clients" on the setup for the Express.
If the wireless signal is not strong at the location of the Express / Dell, you might also consider the use of ethernet power line adapters. I've had very good luck with these devices and find that overall, they perform faster and more reliably than wireless.

Internet downloading in windows 7 very slow

hi...
      am using windows 7 64bit before i used windows 8.1 delete and install windows 7 64bit now w my downloading internet speed is very very slow... am getting just 1 mbps fast ... but in my laptop am getting more than 40mbps... not in pavilion desktop...
       both runs on windows 7 64 bit... but my laptop is sony vaio.....
               thats a brand new system i didnt get the proper driver networks from hp for windows also.. then find it and solved it... but my downloading very slow...

Hello @vijay79,
I understand that after downgrading to Windows 7 your internet speed has slowed down. What connection type are you using to connect to the internet wired or wireless? Have you ensured that you have installed all the drivers from the HP Pavilion Desktop - 500-400na - Software & Drivers page? If not please do so.
If after you have ensured that all the drivers are installed you still have the slow speed issue please re-post with the answers to my questions and I will be happy to help you further. Thank you for posting on the HP Forums. Have a great day!
Please click the "Thumbs Up" on the bottom right of this post to say thank you if you appreciate the support I provide!

WRT54G very SLOW Wireless

All-
I hope someone can help me with this problem. I have a WRT54G v8 router and a PC with Vista. My ISP is Comcast, and I am paying for 12 Mbps. When I plug my computer directly into the modem or router I get speeds usually about 6 Mbps, sometimes up to 8 or 10 Mbps. However, when I connect to the internet through my wireless connection it is VERY SLOW. The connection is only about 200-400 Kbps. I have all ready spoken to one of the technicians at Linksys. They advised me to change the following settings:
On the setup tab, Make MTU "Manual" and size 1365.
On the Wireless tab, set to Channel 11.
On the advanced wireless settings, set Beacon Interval 50 and Fragmentation Threshold and DTIM Interval to 2304.
In the Security Tab, uncheck "Block Anonymous Internet Requests" box.
I made these changes, but my connection is still very slow (380 Kbps).
Help!
Thanks!

As you have already made the changes on your router, and still its not working. Have you tried upgradeing the firmware of your router? If not then you can Go to website linksysbycisco.com/downloads.........insert model no of your router in serach tab......select proper version of your router........download the firmware file......save that file on desktop.
Follow these steps to upgrade the firmware on the device : -
Open an Internet Explorer browser page on a computer hard wired to the router...
In the address bar type - 192.168.1.1...Leave the username blank & in password use admin in lower case...
Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on "Upgrade"...Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say "Page cannot be displayed".
Now reset your router : Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...
Once you configure all the settings on your router, Below are the wireless settings which you can change on your router.
Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.1
Leave username blank & in password use admin in lower case...
For Wireless Settings, please do the following : -
Click on the Wireless tab
-Here select manual configuration...Wireless Network mode should be mixed...
-Provide a unique name in the Wireless Network Name (SSID) box in order to differentiate your network from your neighbours network...
- Set the Wireless channel to 11-2.462GHz...Wireless SSID broadcast should be Enabled and then click on Save Settings...
Please make a note of Wireless Network Name (SSID) as this is the Network Identifier...
For Wireless Security : -
Click on the Sub tab under Wireless > Wireless Security...
Change the Wireless security mode to WEP, Encryption should be 64 bits.Leave the passphrase blank, don't type in anything...Under WEP Key 1 type in any 10 numbers please(numbers only and no letters eg: your 10 digit phone number) and click on save settings...Please make a note of WEP Key 1 as this is the Security Key for the Wireless Network...
Click on Advanced Wireless Settings
Change the Beacon Interval to 75 >>Change the Fragmentation Threshold to 2304, Change the RTS Threshold to 2304 >>Click on "Save Settings"...
Now see if you can locate your Wireless Network and attempt to connect...

Remote Desktop To Windows Server Very Slow

I have OS X 10.6 running on a MBP and a problem that seems to be growing worse over time. I am using Remote Desktop (both CoRD and Microsoft Remote Desktop) to gain access to remote servers. One is a Windows Server 2008, the others are Windows Server 2003. Initially all was fine, but over the last 2 months access to the W2K server has crawled to a halt. Now, when accessing the other servers I'm having the same issue. I have tried different clients for remote access, used different high speed Internet connections (FIOS, a private network) and the result is the same. Very, very slow connections.
I have also tried using a different login on the laptop to no avail.
I booted Windows on my MBP using Parralels Desktop and tried using Windows RDC to the same servers; that works fine. In fact, I can access the servers very quickly using my iPhone's Remote Access software using the same Internet connection (home WiFi) as my MacBook Pro.
So I can only assume it's an issue with OS X 10.6, since different devices using the same Internet connection can make a much faster connection. But I can't find any similar posts on the issue.
Any ideas are appreciated!

Hi Jason,
From the error message, it seems that take time to load the user configuration properly from the server and then the network connection was slow. Please refer to following article

Sqlsrv very slow over network

I'm using sqlsrv (php_pdo_sqlsrv_55_ts.dll and php_sqlsrv_55_ts.dll) in PHP (5.5.12, CLI version on Windows 8.1) to connect to a SQL Server 2012 over a VPN tunnel. But the transfer rate for large result sets is very slow.
Testing SSMS on the same PC over the same VPN tunnel for this query (query is just for testing purposes, I also tried other queries with large data sets and all showed the same performance issues):
    SELECT *
    FROM [Data].[dbo].[Logins]
    WHERE date >= '2014-01-27 00:00:00.000' AND date < '2014-01-29 00:00:00.000'
returns about 100,000 rows in 4 seconds. Checking the transfer rate on my firewall/VPN shows 2,500 KB/s (on a 100mbit network) while the query is running.
Using PHP:
    sqlsrv_configure('ClientBufferMaxKBSize', 1024*1024);
    $dbconnect = "SERVER\\HERE";
    $dbconinfo = array("UID" => "user", "PWD" => "pass", "Database" => "Data")
    $conn = sqlsrv_connect( $dbconnect, $dbconinfo);
    $sql = "
    SELECT *
    FROM [dbo].[Logins]
    WHERE date >= '2014-01-27 00:00:00.000' AND date < '2014-01-29 00:00:00.000'
    $options = array();
    $options["Scrollable"] = SQLSRV_CURSOR_CLIENT_BUFFERED;
    $options["QueryTimeout"] = 30000;
    $stmt = sqlsrv_query( $conn, $sql, array(), $options);
runs 40 seconds and the firewall/VPN shows less than 150 KB/s while the query is running. Task-Manager shows around 5% CPU load for the script.
I used SQLSRV_CURSOR_CLIENT_BUFFERED just for testing, because it reads the result in its own buffer without any further PHP code. Fetching each set of data without buffering is just a little bit slower (around 45 seconds).
I also tried a PDO version which lead to the same result.
ConnectionPooling 0 or 1 didn't make any difference either.
Changing server name to DNS vs. IP adress also made no difference.
LogSubsystems -1 and LogSeverity -1 did not show any issues or anything helpful at all.
I even used Wireshark to watch the network traffic but couldn't find any big differences between PHP and SSMS versions. But I don't know too much about networking layers.
So the CPU load is low, there is no HDD use at all, the network transfer rate is extremely slow and the SQL server would be capable to deliver the results very much faster. And it actually is a lot faster with SSMS on the same PC and network connection.
Why is sqlsrv so very slow?
Any ideas what might be the issue or what I could try to speed up PHP/sqlsrv would be greatly appreciated.

Please tell us what are waits assigned to query, you can use below tsql code to get the information.
select session_id, t.text, start_time, status, command, db_name(database_id) As DBname, USER_NAME(user_id) As UserName, blocking_session_id, wait_type, wait_time, wait_resource, percent_complete from sys.dm_exec_requests
CROSS APPLY sys.dm_exec_sql_text(sql_handle) as t
This information can help us to understand the problem.
Thanks,
Shashikant
Sadly I don't have the rights on the SQL Server for this query. But from what I gathered from similar issues on the web, SQL Server is most likely waiting for the client.
I also tried the same testing query now with Power Query in Excel. It's as fast as with SSMS. Just with sqlsrv on PHP it's extremly slow.
Testing the query on a local SQL Server, it's pretty much instantaneous with SSMS, Excel and sqlsrv on PHP as well.

Windows 7 VERY slow browsing and creating folders

Hi!
I'm having a rather strange problem with Windows 7 RC. I've noticed that browsing folders is generally slower than in WinXP, but still acceptable. But lately I'm having a lot of difficulties moving files, creating folders, renaming folders and files, and even waiting for an Explorer window to refresh after some external app has created or modified a file. Sometimes I have to wait up to 30 seconds for a new folder to be created, and another 10 or 15 after I rename it (from "New Folder" to whatever else).
This does not happen in every folder in my HDD, but I don't know exactly in which ones. I thought it was the indexed folders, so I removed a few from the Windows Indexing database, and they were still slow (after system reboot and all). Then I thought it would probably happen in folders that are part of a library, so I removed them and the problem was still there. I can't think of another reason for this to happen in some folders and not others. It seems to happen in my frequently used folders, which honestly sucks.
Just for the record, here's my system's specs:
Dell Inspiron 9400 laptop (e1705), late 2006 model
2GB DDR2 667 ram
320 GB 7200 rpm seagate HDD, aftermarket (really fast drive, not the problem here)
Intel Core Duo (Centrino Duo) 2.0GHZ
Windows 7 RC, multiboot with WinXP
Thanks!!!

For the benefit of those who are being driven nuts with SLLOOOWWWW Explorer 'Problems', I list the methodology which has worked for me.
As always, 'Use at Own Risk' and 'Your Mileage May Vary'.
Do NOT repeat NOT perform these steps unless youfully understand the ramifications and are prepared to live with the consequences.
BACKUP FIRST !!! - Create a RESTORE POINT!
The latest incarnations of Windows attempt to 'out-think' the user in order to provide a 'Better Computing Experience', and that is well and good for the average Joe-Blow, but NOT what the Power-User wants or expects. There are MANY suggestions as
to the cause and solution(s) for slow Explorer response, but we have to remember just how much work is going on behind the scenes.
Much of that work is to provide 'pretty' screen enhancements and to make for 'simpler' Searching. By foregoing some of these we can reclaim quite a lot of CPU cycles and Disk I/O for our own (Applications) use.
Before you embark on any changes, carefully assess just how you use your PC. - How important are Thumbnails? - What value does Content View really provide? - Can you implement a Folder structure and File-Naming convention which makes Snippets and Content
indexing of little use?
You'll still be able to see local thumbnails if that's what you want, they will just be remade each time you open the folder and select Thumbnail (Large Icon) View. This is usually less bothersome than the time loss of having a 'Master' Thumbnail
cache maintained and updated for every file operation.
Certainly, some 3rd Party 'add-ons' (Power Archiver for one! & similar) may cause problems, as can poorly configured A/V programs (realtime checking of Notepad for instance, every time it is opened??? Why not bring back the old innoculate method?) -
but I digress.
For many, the slow Explorer problem exists without any of the suspects / causes mentioned in previous Posts, or elsewhere online.
I repeat: 'This methodology has worked for me - Your Mileage May Vary'.
Now for the fun & games:
Kill the time and resource hog 'Indexing Services' - Plenty of advice on how to do that is available online.
DISALLOW Indexing on all volumes.
To retain the ability to search for my files, I have been using the Search Everything tool from:
http://www.voidtools.com/ which searches ONLY on local or removable NTFS volumes. (ie NOT FAT32 USB Drives!) But that poses very little problem when I examine my real-world use of any Search Tool.
SE needs Administrator privileges for its low-level file-system access, certainly not an issue to have a responsive Global Search at your fingertips.
With 34.5 Gb (> 137,000 files in > 20,000 folders) on HDD, and 627 Gb (> 2,300,000 files in > 82,500 folders) on a Portable USB Drive, Search Everything has about 74Kb RAM usage and the db file is 10.5 Mb on disk - not a huge overhead.
The initial run occupied about 10 minutes of my setting options and less than 5 minutes for the building of the database.
The online FAQ has plenty of information including how to use wildcards, Path Matching, boolean operators and regex use.
With a lean mean responsive search at hand, now to clobber some more of the 'features' which are supposed to 'help' us in our computing experience...
Big Guns Time!
Start Group Policy Editor -
Start > Run > gpedit.msc
Navigate to:
Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Windows Explorer
Locate and ENABLE the settings as listed:
1. Turn off the display of thumbnails and only display icons on network folders
Disables the display of thumbnails on network folders in Windows Explorer.
Windows Explorer displays thumbnails on network folders by default.
If you enable this policy. Windows Explorer will only display icons and never display thumbnails on network folders.
That gets rid of the first time-waster - Network access is slow enough without adding the extra traffic for thumbnails, and many PCs are stand-alone anyway.
2. Turn off the caching of thumbnails in hidden thumbs.db files.
Turns off the caching of thumbnails in hidden thumbs.db files.
This policy setting allows you to configure Windows Explorer to cache thumbnails of items residing in network folders in hidden thumbs.db files.
If you enable this policy setting, Windows Explorer does not create, read from, or write to thumbs.db files.
If you disable or do not configure this policy setting, Windows Explorer creates, reads from, and writes to thumbs.db files.
This goes hand-in hand with 1.
3. Turn off Windows Libraries features that rely on indexed file data
This policy setting allows you to turn off Windows Libraries features that need indexed file metadata to function properly. If you enable this policy, some Windows Libraries features will be turned off to better handle included folders that have been
redirected to non-indexed network locations. Setting this policy will:
* Disable all Arrangement views except for "By Folder"
* Disable all Search filter suggestions other than "Date Modified" and "Size"
* Disable view of file content snippets in Content mode when search results are returned
* Disable ability to stack in the Context menu and Column headers
* Exclude Libraries from the scope of Start search
This policy will not enable users to add unsupported locations to Libraries.
If you enable this policy, Windows Libraries features that rely on indexed file data will be disabled.
If you disable or do not configure this policy, all default Window Libraries features will be enabled.
Well, with Indexing turned OFF, this one is a real no-brainer, isn't it?
4. Turn off the display of snippets in Content view mode
Disables the display of snippets when Content view mode is turned on.
Windows Explorer shows snippets in Content view mode by default.
If you enable this policy, Windows Explorer will not display snippets in Content view mode.
That stops peeking into every file and trying to decode the snippet - MORE time-saving.
5. Turn off caching of thumbnail pictures
This setting controls whether the thumbnail views are cached.
If you enable this setting, thumbnail views are not cached.
If you disable or do not configure this setting, thumbnail views are cached.
Note: For shared corporate workstations or computers where security is a top concern, you should enable this setting to turn off the thumbnail view cache, because the thumbnail cache can be read by everyone.
It (IMHO) is faster to generate the thumbnails as needed (for my usage anyway), rather than to be attempting to maintain a global cache each time a file is created, modified, deleted or moved.
This completely cuts out the thumbnail caching overheads, and makes quite an impressive speed difference. Even on an old 1.7 GHz Laptop with 2 Gb RAM and an Intel 915GM Graphics Card (NOT the best choice for Win 7 by any means!).
6. Turn off numerical sorting in Windows Explorer
This policy setting allows you to have file names sorted literally (as in Windows 2000 and earlier) rather than in numerical order.
If you enable this policy setting, Windows Explorer will sort file names by each digit in a file name (for example, 111 < 22 < 3).
If you disable or do not configure this policy setting, Windows Explorer will sort file names by increasing number value (for example, 3 < 22 < 111).
Do I REALLY want to waste the time on this procedure? If I want to sequence my files, I'll prefix the filenames with 0's - 003 < 022 < 111. Not a problem!
Subjectively, these changes make for a much more responsive system.
Objectively, moving over 2.3 Gb (7,500+ files) via 'Drag & Drop' from HDD to USB Drive shrank from 12 Mins+ to about 8 Mins. Explorer did NOT 'freeze', and I could freely change the displayed folders in both the Source and Target Explorer windows.
I hope that this is of use to others, it has served me well for the last several months.
A few minor delays when wanting thumbnail views, but certainly FAR LESS DELAY than before the changes, and
no more stalled Explorer.

Very Slow Wireless on New MacBook Pro

Hi just bought a 13' MacBook pro about a week ago. Immediatley from getting it my wireless internet is very slow. We have a few other pc's in the house that use the same router and they all run fine on the wireless, even our phones run great. When I am plugged in with the ethernet cable the internet seems to work fine but as soon as I am wireless it takes forever. Pages will take minutes to load up. I was on the phone with mac support and what they did didn't seem to fix the problem. I am getting so frustrated and would really like any help. Thank you.

In the Belkin config, have you got 'Protected Mode' On or Off? (Wireless > Channel and SSID > Protected Mode) It's generally faster Off unless a lot of 802.11b devices on your network.
Packet loss or packet re-ordering might cause that drop, as might a high MTU value, but it's hard to troubleshoot ...
(I'm using a Belkin G+MIMO and getting as fast/same performance as hard wired machines)

Very slow downloads Network test says "can't connect to Apple"

Have a 1st generation ATV and it has been working great for years until now. When I have slow downloads so I go to "Test Network" and it fixes the problem, but not any more. Now it says "can't connect to Apple"
Funny thing is it can connect but it is very very slow!
I have tried most everything I can think of this has got me stumped!
-- Speed test on my network shows I am getting 12 Mb/s download speeds with Comcast cable
-- using an Apple Airport extreme
-- I have NOT done any changes to my network
-- Have done a factory reset on ATV
-- rebooted my Airport
-- Made sure all my updates have been done
-- Hooked ATV up with ethernet cable to network that just seemed to make to worse! strange?
-- look all very the boards
Does any one have any ideas?
Thanks!

I have the same experience, i.e., "Test Network" used to improve slow downloads, but now when I attempt it, the test download progress bar moves, but then I get the "can't connect to Apple" error message. I have not yet found a solution to this, however it may be related to the following problem:
ATV does not remember wireless network password.
▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔
I am having to re-enter the wireless network password every time the ATV starts up, and sometimes during startup it appears to be in a Catch-22 situation where it is trying to access the network but cannot because it has not yet let me manually enter the password, so it spends a long time with amber or amber plus white light blinking, and then more time with solid white light before finally showing the startup sequence, about half an hour after being switched on.
See post about password problem at http://discussions.apple.com/thread.jspa?messageID=13182180#13182180, which also lists my equipment.

Windows Vista = very slow wireless network
