Glad you can get it going again

At least THAT'S a bonus.

Your router is inside of your computer? Maybe that's part of the problem. It gets and stays pretty warm in there. And if it goes back to default on shut-down, I would assume that its volatile memory is being lost ......... much like what happens if the C-Mos battery goes dead in one's computer. It wouldn't happen to HAVE a small LiIon button battery inside, would it?
