Linksys Wireless Router :: WRT120N Keeps Resetting On Its Own?

My roommate and I recently got a WRT120N to replace an older Linksys router that was exhibiting the same problems with less frequency. Indeed, the entire reason we got the new router was to fix these problems. Alas, they have become worse.Anyways, what's happening is that the router constantly resets itself. It does this every 20 minutes to an hour and doesn't seem to be related to how much traffic it's dealing with.It's not just the internet going down, it's the entire network, and not even just the wireless part. My computer has a wired connection to the router and, and I get told "A network cable has been unplugged" every time it happens. Then, if I look down at the router, I see no flashing lights, just the steady glow of the power light. It always fixes itself after 10-15 seconds, but it's very annoying. Certainly, playing games online or having a conversation on Skype is made more difficult.As previously mentioned, we replaced our older router because it was exhibiting the same behavior, but the new one does it with greater frequency. At the very least, the router does reset itself instead of needing us to cycle the power. The setup was slightly different with the old router: I was using a wireless connection with a WMP54Gv4 which I've had to disable since it bluescreens the moment it so much as sniffs a signal from the WRT120N?
