Wireless Linksys router WRT55AG wacked out.  

I have a wireless router that is just going out on me (I think). Here is the scenerio of what's happening. When I plug the power in to the unit it all lighs up blinking like it's transfering data. But after lets say 10-30 sec the whole led lights just goes black for a second then the whole thing flashed green led comes on all at once then it goes back to blinking again. And the whole cycle starts all over again.

To me it seems like the router just does it's on power down and reset the unit on its own. Here is what I've done so far:

I've upgrade the firmware,
I've hard reset the unit,
I've try different power strip,

Nothing seems to work, does any one have a suggestions? This could be in it's last leg. I think I will need to go out and just get a new one.
