Solution for Vista Wireless Spikes on the G50V

Hello, I have found a solution for the infamous "Vista Wireless 30-60 second lagspike issue" after spending some time in Microsoft's Knowledge Base (which is made of win, really) and their community sites.

Quoted from here

Basicly what I did was go into the Advanced Tab on my network adapter, Disable 802.11n mode, set Wireless Mode to 802.11g and presto; no more lag spikes.



I am aware this gimps the potential of my wirless card (down to 54mbit), but frankly I don't care as I don't need anything more than that when I'm gaming or downloading as my internet connection is at 20mbit. The only thing that will suffer is internal network transfers, but again I got other methods for transferring huge amounts of data on my home network.

That's the con, and the pros are:

• No need for VAL tool
• No need for Netsh scripts
• No need for Optimizer tools
• No more smashing your keyboard while gaming online.

The proof, I can ping my router without any failed packet transmissions:

Before the issue was solved, a timeout (or a very high latency number) would appear regularly, as you probably know if you have experienced the issue.

I now enjoy playing WoW, WC3 and CoD4 without any lagspikes Hooray!


Note: I posted something similar as a response to another thread on this issue elsewhere on notebookreviews, but I figured I should post it in the Asus section as well because the solution might only apply to the G50V laptop.
Hope this works for you if you got this problem. I sure spendt many hours trying out the different Vista WLAN optimizer tools/tweaks/scripts to solve the problem, so posting here to prevent you from doing it too.

 

There have been some other internet issues with Vista in the past that required a different fix, I had it in WoW back in the day and totally forgot what I had to do to fix it. I mean insane latency.

I do not recall but I think it effected the wired and wireless.

I had t use an advanced tool to disable one of the new internet functions vista adds. I really want to know what it was so I can add it in here as more info, also because I myself want to remember the fix incase I have the issue again. I guess maybe a patch has fixed it since I have not noticed it anymore and have had new systems since.


As for your problem & solution specifically:

If you have N card & router you could also set your router to G/N only and not limit yourself to a G connection.

 

Aha! found it!

This is very important - Netsh int tcp set global autotuninglevel=disabled

I would read into what the command does, but it was trying to do something, its a new feature in Vista and it was killing my latency, after I turned it off just like magic all was well.

 

This issue in particular is caused by a Vista 'feature' where it halts network traffic to search for a better access point. This cannot be turned off (it's a service called WLAN Autoconfig). When you turn it off, Vista will not be able to connect to the network like XP could.

If you google "Vista Wireless lag spike issue" you'll find tons of threads on various sites which tells about this problem and various solutions towards it which works for some people but are useless for others. Widely mentioned is the VAL tool, which does not work on the G50V.
Another is a Netsh command, netsh wlan set autoconfig enabled=no interface='Wireless Network Connection', which partially worked but didn't completly resolve the issue as you would still get frequent lagspikes. It also had to be run with the countervalue to enable WLAN autoconfig again after reboot/disconnect to be able to connect to the network again.

I merely posted here to tell G50V owners that this fixes the problem for our laptops, that's all. (Tried and proved successful on two G50V machines myself).
I'm sure there are other and probably better workarounds for this problem, but this one should work for sure.

 

I have never had this issue (at least not noticeably) I have played FFXI online with no lag (at least nothing longer then a fraction of a second), if I do this will it even stop that lag?

At the same time I tend to be in places with very good connections (home and school show full bars) so vista may not even be looking for other connections.

 

Update: This also works on Windows 7.
