It's been randomly kicking me on and off, and now the intervals between disconnects is getting shorter and shorter. My brother, who is hardwired into the router, is also getting randomly disconnected. I've also seen it disappear completely (and then reappear) from the wireless network list.
I'm guessing it's pretty much dead.
The disconnecting has become such an issue that I'm using my phone as a modem right now. Works pretty well, I must say!
