Starting today, I have been experiencing ping spikes while playing a few games. It happens on every game but only on this computer - my other computers which share the same router have no problems. I have run a ping test in command prompt:

Instead of pinging Google try pinging your router address. Do you see the same spikes? If not, then try pinging the next hop after that. If it is happening for just your computer, perhaps you have some scheduled task that is saturating your network. –  Zoredache Apr 12 '12 at 18:38

Maybe fire up resmon and watch the network tab? –  Zoredache Apr 12 '12 at 19:08
    
Do the other computers also connect via WiFi? –  Daniel Andersson Apr 12 '12 at 19:22

One solution to this problem appears to be to install and use Vista Anti-Lag, according to this article. VAL 1.1.1 can be downloaded here.
