I updated the firmware and now I can't connect to the internet. Everything seems to work fine (green light on AEBS, correct lights on my Comcast modem, seems to get an IP address, etc.), but I open up Safari and get "You are not connected to the Internet." I've tried resetting the modem, resetting the AEBS, but no luck. I tried rolling back, but there is no option in the pulldown for any other firmware. I'd browse to it, but I don't have it. Please help! I can't find it anywhere on the net!
