The router was flashed from v1.1 of HyperWRT to v2.0. Afterwards the Internet LED on the router was off, as was the PC Activity LED on the modem it is connected to. I reset the router, unplugged it, and finally flashed it back to v1.1 with no result -- it acted as if it wasn't plugged into the modem at all. If I unplug both the modem and router, then plug back in the router, the Internet LED will stay on, indicating that it is connected; when I then turn on the modem the LED alternates between staying off and blinking for 1-2 seconds. I am utterly perplexed and at a loss of ideas, besides parting with $50 for new equipment. :?
