Lag spikes in wireless gaming

Hello!
I know there has been a few posts about this, when i ping google for example i get 50ms for like 10-15 ticks and then when my wireless connection refreshes its signal strength it will spike to 1k+ms. and does so every 10 seconds or so... i was reading the other threads about this issue and i saw that stoping windows zero would fix the issue... i have done so and it has not fixed the issue.. i have Windows XP pro and Belkin N wireless adapter.. i know there is something wrong with a setting on my comp or something because when i do the same thing on my Laptop i do not get those spikes... I have been fishing around the net for about a week now to see if i can find a solution but nothing that seemed to work.. also if i connect to the neighbors network(they dont have it protected) it does the same thing when the signal refreshes... Pls anything suggestion will help. (pls no "Just get a wiredconnection" ) response. Maybe if there is a way.. even if you set it low to force the comp to stay a speed i dunno... im totally out of ideas pls help.
