bet you can't figure out my wireless lag spike, plz help!

here's the deal. new AM2 shuttle LAN box, got a usb wireless card in there because I have no PCI slots. I have a dlink DI-634 router on road runner. everything works fine when I have a cable plugged in but as soon as I use a wireless USB device, I get a horrible lag spike every 60-70 seconds. it's cycular. this lags everything to about 1.5 seconds and is horrible for gaming to say the least. I use the wireless USB because I can't pull lines through where I live to answer that question. regular ethernet works fine.

the wireless devices I've used are belkin's wireless g mimo card and after that was giving me the same problem, I switched to a d-link rangebooster g wireless card. same problem. I only have 64 bit WEP protection going. I've tried both brand specific configuraiton software and the windows zero configuration. I disabled network location, netbios and a couple other services to have the same effect.

I've ran a continuos ping and task manager to see if CPU usage goes up during the lag spike and nothing. I've ran kerio firewall to see if something else is causing it but I couldn't find anything. I'd replace my USB drivers but nvidia doesn't seem to have any.

is there anything I'm not aware of or missing? please help!

Do you have a 2.4Ghz cordless phone? If so, that phone could definitely be causing the problem. Other high EMI devices such as a microwave nearby could also cause the problem.

There might also be another wireless network in the area that is interfering with your wireless signal and causing the latency problems. Run NetStumbler on the PC and search for any other network devices in the area that are on the same (or similar) wireless channel to your router. If so, change the channel on your router to something that is as far away as possible from other networks in the area.

no phones, nothing like that. as for netstumbler, my router is the only thing showing up.
