Vista and Windows 7 scans for wireless network every minute which can interrupt online gameplay and cause streaming videos to stop. But there are ways to fix the lag.

In Windows Vista and Windows 7, the operating system scans the wireless spectrum every 45 seconds to look for a more preferred wireless access point (AP) than the current one. According to MSDN, the wireless driver must not perform any scans while data is being streamed. Unfortunately, these scans cause streaming data including online games, Youtube videos, and internet radio stations to be interrupted as frequently as every 45 seconds.

Even though wireless autoconfig for preferred AP causes problems for many users, Microsoft will not remove this feature from the default OS configuration. Unfortunately, disabling wireless autoconfig also stops all wireless connections immediately.

Some typical games that are negatively affected by wireless lag include World of Warcraft, Battleforge, and Team Fortress. Dying in an online game because of lag can be frustrating.

Before proceeding, users on DSL may want to check to see if their wireless router is causing the lag.
Testing Wireless Lag With Ping

To see if wireless lag is a problem, bring up the command prompt and type "ping -t www.google.com". Look at the number for "time=". After every 30 seconds to 2 minutes, one or more of the packets will be much higher than the rest, often above 1000ms.

If other symptoms show up such as dropped packets, the problem is something else such as a problem with the wireless router or internet service provider. Lag can be caused by other network issues such as ISP issues and poor wireless signal quality.
Disabling Vista's Wireless Autoconfiguration

To disable this feature, a replacement wireless client is needed that can connect the computer's wireless adapter to other wireless networks. Normally, the client is downloaded from the support website for the wireless card or computer manufacturer. In notebook computers, the wireless drivers are usually downloaded from the notebook manufacturer's support website. In some cases, a utility may not exist or may run on top of Vista's wireless autoconfig, which means disabling Vista's Wireless Autoconfig means disabling wireless internet. In those cases, the user needs to buy an extra USB wireless adapter that can bypass Vista autoconfiguration.

If a replacement wireless client has been found, click on the Windows icon on the lower left of the screen, the right click on Computer and select Manage. Go into the Services menu and disable "WLAN Autoconfig" service. Keep in mind that disabling the service will disconnect all wireless connections immediately. To restore wireless service, enable the auto-start then start the service manually.

Once Vista's WLAN Autoconfig service has been disabled, use the replacement wireless client to connect to wireless networks instead of using Vista or Windows 7.
WLAN Optimizer and Vista Anti-Lag (VAL)

WLAN Optimizer, written by Martin Majowski, fixes this problem in one small program that's designed to work in Vista and Windows 7 by changing the configuration of Vista's wireless service. This is a freeware program that disables the automatic scans for wireless networks. It can be configured to start automatically along with Windows once the user determines that it fixes the wireless lag. An additional feature of WLAN Optimizer is that it can be configured to turn on streaming mode, which could also stop the lag in streaming data such as Youtube videos. If the program stops running, all settings revert back to the OS defaults so there are no permanent changes if WLAN Optimizer doesn't work. Another program that may work is Vista Anti-Lag (VAL).

For some, both WLAN Optimizer and Vista Anti-Lag do not work. For these users, they need to find a replacement wireless client or perhaps try another wireless adapter which comes with a Vista utility.

Finally, some users have seen success from disabling Windows Defender or the Base Filtering Engine from the Services menu in Control Panel. Keep in mind that both of them reduce system security significantly.

Although the wireless lag seen in many Vista and Windows 7 wireless connections is very annoying, it's something that can usually be fixed by working around Vista's and Windows 7's wireless auto configuration.

Windows 7 freezes randomly for 30-45 sec - Solved - PCSTATS.com Windows 7 freezes randomly for 30-45 sec - Solved
Wed, September 15 2010 | 5:22PM | Filed under: Tips| PermaLink Posted by: STAFF

After a grueling 12 hour stretch trying to find the solution to why Microsoft Windows 7 would randomly freeze up and not respond for about 30-45 seconds, PCSTATS finally, successfully, found a fix!!!! When Windows
makes you work for a solution to one of its many problems, it really makes you work hard!

The Problem: - Windows 7 would randomly freeze for about 30 seconds, while frozen there would be no error messages or BSOD.... the mouse still worked, but icons and windows and even task manager didn't respond. After 30-45 seconds the computer would come back to life and act normally as if nothing had happened. This problem with Windows 7 freezing would happen at random times, in random applications. Most frustratingly there wasn't an apparent trigger. Nor were there any signs anything had happened immediately after the computer momentarily froze. Task Manager showed nothing. There was no crash message, no BSOD error message, nothing showed up in Event Viewer... there simply wasn't a trace.

PCSTATS tried a number of solutions that didn't work:

Changing the computer power mode to "High Performance" (no change)
Updating every single hardware driver
(no change)
Patching the OS to the latest updates (no change)
Update to the latest BIOS (no change)
Disabling Services, cleaning out MSCONFIG (no change)
Virus Scan and Malware searches (nothing showed up)
System Diagnostic scan (no problems, no change)
MemTest or Memory Diagnostic (no faults, no change)
Installing more memory wouldn't have changed anything as this issue is not an memory problem.

Short of reinstalling Windows 7, we'd exhausted just about every problem solving solution in PCSTATS's extensive Beginners Guides. After wading through countless forums it became clear that reinstalling Windows 7 wasn't going to fix anything either.

Based on systematic troubleshooting; 1) update all drivers, 2) update BIOS, 3) ensure no hardware faults by testing with diagnostic programs 4) updating graphics drivers 5) cleaning out MSCONFIG 6) scanning through Services and last but not least 7) contacting the manufacturer Support department for Tech Support help (no help, recommendation was to reinstall from factory OS image) we had eliminated most of the potential errors that normally would be responsible for a computer crashing, hanging or freezing up.

In the end, we did everything right. It wasn't any one of these things. It was a much more complicated issue solved with a very specific Microsoft Knowledge Base Patch released just two weeks ago!

PCSTATS' solution was to apply Microsoft Hotfix KB2265716 and restart twice.
Hotfix KB2265716: A computer that is running Windows Server 2008 R2 or Windows 7 stops responding randomly
Let PCSTATS know if this tip helped you solve the maddening Windows 7 Freezing Randomly for 30 seconds issue with your PC
