My pc has been running at low latency for a while without a problem until suddenly it lagged the hell out of everything, when this started i had a latency/ping of around 300-400ms on average, sometimes even 1000ms. Now I’m back down to 30-60ms and lowest I had was like 13ms. Here’s what I did.
Step 1.
Ok first thing I did was (This can be skipped btw) is I installed cFosSpeed (Click here for the Trial), This prioritizes gaming, normal browsing etc. and gives downloading etc. a lower priority. After installation it asks to reboot, Let it reboot.
Now the fastest way to get it to work optimally is to upload a big file somewhere or something similiar (Send yourself a big file through email.) more info about that here. If you don’t do this it might take a few days before it’s calibrated. Once again this is optional, And I’m not going into detail how to work with this.
Step 2
Ok now we need to do some registry tweaking, and some command line stuff. However we don’t need to do it ourselves. There’s a website called speedguide.net that has a script called SG Vista TCP/IP Patch. If you don’t trust it you can find the manual instructions here (And a guide to how the registry works here) and if you do trust it the script is here (Right click->Save As) after downloading open/run the script and once it opens you have 4 choices:
- “Y” To optimize Vista TCP/IP settings
- “Q” To disable QoS reserved bandwidth
- “D” To revert to Vista default values
- “N” To cancel patch and exit
Now just hit Y and it will optimize the settings. Now after this run it again but this time press Q, After this is done again reboot.
Now if the problem got worse just run the thing again but press D, and if your lag isn’t high anymore or lower then it was, good, that was our goal.
Step 3
Now we need to uncheck some stuff on the network connection, It’s simple to do but it does have some impact (Well it did for me).
Ok let’s start first thing to do is launch the control panel, Open the start menu and click Control panel on the right. Now the control panel will appear. Now if your control panel is set at classic open Network and Sharing center. If it’s set at normal view click Network and Internet and then open Network and Sharing center. Now in the left bar click “Manage network connections”. Now a window will open with 1 or more network adapters (Icons) there should be one that sais Wireless Network Connection or something similiar, and it should have the name of your wireless network below the that.
Now right-click it and click properties. Now a new window comes up with in the middle a box with checkboxes on the left and some text next to them. What you now need to do is uncheck “QoS Packet Scheduler” and also uncheck “Internet Protocol Version 6 (TCP/IPv6)”, You can uncheck them by clicking on the checkboxes. See image below (It’s in dutch but well the names are pretty much the same):
Now after that just click OK and wait for the window to disappear.
Step 4
Now, First test out if the lag is gone, If so, Good we solved it, If you have lagspikes every 30-60 seconds and you have a wireless connection continue reading. And if you still have normal lag try asking at one of the windows help forums.
Now the reason this lag occurs is because windows vista scans for wireless networks every 60 seconds. We are going to use Vista Anti-Lag. You can download the setup here and the rarred version without installer here.
Now install or extract the program and launch it(If you’ve downloaded the rarred version open val.exe). A window similiar to the following will pop-up:
Now just hit the Activate VAL button and it will disable the automatic scan for as long as it’s running. Now for me this step wasn’t needed so I didn’t do it, But it might do the trick for you. Now go test if this fixed it if it did, Make sure you start Vista Anti-Lag every time you start your computer (Or when you play a game whatever you like), And the lag should be gone.
Now if you have any questions, comments don’t hesitate to leave a comment and I’ll reply as soon as possible.

Very nice tutorial! But, I rather do things manually. Now a days it is really risky to download little programs that claim to improve the pc performance by tweaking the registry. Most of the time, this programs have Spyware, Trojans and more. You will really get lucky!
Thanks!
Well arnold, The SG Vista TCP/IP Patch is just a text file with batch commands that execute the commands you need to execute and adds the keys to the registry you need to add. And well the Vista Anti-Lag doesn’t really have an alternative afaik.
