Thanks for testing it out. I did some tests by cutting power to router, plugged it back in and it came back on it's own, pretty quickly. Then cut the power to the modem. plugged it back in and it took 2 1/2 minutes to come back. Tested again and it came back after about 2 1/2 minutes. This is obviously way too long, but it worked. I could see the lights on the cable modem coming on one by one. I suspect that the 4th one is internet. As soon as the 4th light stopped blinking and stayed on, I had internet.
Only tried twice but could not replicate the "never came back on unless I unplug/replug the WAN cable" problem.
Maybe I will take the cable company up on their offer for a new modem.

I had my cable company replace my modem and that resolved my issues. It is definitely worth a shot!
