Windows 7 Internet lag - yes I searched forums first

When I searched for this exact problem, I found a lot of threads, but none which could explain the problem (and I found very few people on those threads were helped with the answers there either, most answers blaming it on external things). I'm convinced the problem is with Windows 7, since the router/modem and all peripherals are the exact same for this computer as my old computer. The whole computer is much improved over the old one. I first noticed the problem after my old motrherboard gave up, and I was given a laptop to use while they put together my new system. The laptop ran windows 7 and the internet lagged. At that point I didn't think much of it, while more modern than my comp, it was still a dated laptop and I figured that was the problem. But the problem persisted with my new computer. The only difference so far being that I'm running windows 7 over windows Vista.

Its the only computer in the house as well.

The problem is visible in online games and communication programs like MSN live, where a lag will suddenly occur, sometimes lasting well over half a minute. Its quite disturbing that my old computer could handle these simple tasks so well, and this greatly superior system can't, solely because its running windows 7.

I hope someone can think of what exactly in the software is causing this and there is an easy solution (something i can turn off).

Any help much appreciated ...

A couple of things come to mind

1-Drivers. Run this latency checker to see if a corrupt (or conflicted) driver is at fault

DPC Latency Checker


2- Homegroup

Homegroup uses IPv6 which some legacy hardware has a problem with. If you are running homegroup, you are using IPv6. To check to see if this is the problem you can create a new network connection using Workgroup (which uses IPv4). If it cures the problem you can disable IPv6 and delete homegroup.

First things first - what are the complete specs on your new computer? Also, what kind of network connection are you using? Get that for us and post a snapshot of your speedtest.net results, and we'll go from there.

make sure your video drivers are installed is it intel graphics,nvdia or ati graphics . is it onboard graphics or a video card also is it a laptop or desktop? Also have you installed the propper drivers for network card?
