Hey guys--

So I have Windows XP SP3 on my PC. I've been trying to fix this problem for a while but I don't really know what is going on. When I use pingtest.net everything comes back normal, and my grade is an A. When I use the command prompt and ping google.com 50 times, it'll come back with around 40% loss saying "Request time out." in the prompt.

I've been getting massive lag spikes in games and browsing the internet. To fix the spikes I have to disable and the re-enable my LAN connection for the network to recover...it wont recover on its own.

I have tried some things such as re installing the NIC driver and making sure Flood Detection is off in my router settings.

The solution may be really simple, but I am not a networking pro.

Any ideas?

Thanks

First, do these things to rule out some possibilities. Use another computer and test the port on the router/modem your computer is normally connected to. Also test the ethernet cable your computer is using on another computer. Scan your computer, use at least 2 scanners to make sure you don't have something nasty infecting your computer.
If you've checked all that and nothing comes up, then there could be 2 possibilities. The NIC itself could be going bad, or obviously there is some kind of software problem. You mentioned that you need to disable/enable the LAN connection to get rid of the spikes. How long before they come back? Does doing certain things bring the spikes back faster? Are the spikes there when the computer boots?

I bet so much money is a process called wuauclt Win XP. Do a ctrl alt delete and check it when you're spiking. XP is notorious for spiking your internet connection with the Windows update wuauclt process. It use to piss me off something chronic when I played Counterstrike 1.6. If it is this, I'd just turn off windows updates and manually update it once a week.

The reason it's such a pain in the arse is because, when you end the process, it fires straight back up again. So you have to completely turn off automatic updates in order to stop it!
