Wi Fi keeps dropping?

I have a Linksys Wireless router/switch with 802.11g. Anyways I've updated the firmware, driver for my wireless card and I still get disconnected way tooo often for my liking.

I lose the signal at least 2-3 times a day. The problem is usually fixed when I just unplug the router and turn it back on. This is getting very annoying is there any way to fix this?

 

No, it's fine when I'm plugged directly in. At least it's messed up like 1% of the time as opposed to 40% of the time when I'm on wireless.

I'm running Windows XP SP2 Professional, I've downloaded every patch I could think of, disabled the firewall, yadda yadda yadda.

It still just loses the signal randomly. I've switched to Linksys because I thought it was higher quality, my last router was absolute garbage. It couldn't complete a single Warcraft game on b.net without disconnecting every single time.
