Problem with wireless connection

[Kyphin]

I'm having a problem staying connected to my wireless connection. I'm using a router and a Wireless network adapter. My signal strength is Excellent and I am using a WPA key. It worked fine for two days but now for some reason it connects for about 3 seconds then disconnects. Then repeats. I'm still able to browse the internet although it's really annoying having to wait for it to reconnect before I click on something. Over and over again. =P

I have a Linksys Wireless-G Broadband router and a Beklin wireless USB adapter.
Thanks in advance for any help at all.

I would make sure the router has the latest firmware and the WiFi adapter has the latest driver.

Next, I would set the MTU to 1492 and disallow fragments
