Linksys WRT54GX2 constantly disconnects

I have had a WRT54GX2 router for over a year now, almost never a problem. All of a sudden in the last day or so the router would constantly shut off and back on again. I noticed that anytime a wireless device tries to connect to the router, the router resets itself, its as if you unplug it and plug it back in, all the lights flash off and it connects again and it goes off again. When it reconnects the connection lasts a few seconds, once I was able to log onto my PS3 account wirelessly during that reconnect for a few seconds, it seemed to work great until it lost the access point cause the router reset again.

I have unplugged the router multiple times. I have connected my computer directly to the line and my internet works fine, in fact the router works fine as long as no wireless device tries to connect with it. I have updated the fireware on the router. I have reset it, reconfigured it, nothing seems to work, I have no clue what to do.
