A couple of days ago my SB6120 started to have the activity light blinking constantly. My first thought was that someone had taken over my PC. Not it.
Had Comcast look at the modem just for grins (I own it). Nothing seemed wrong. I tried moving cables around. Whenever I plug the modem in it behaves this way. Any port in the router. Any port in a switch with nothing else attached. Reset the router and set it up again. No change. The modem still seems to work correctly. I can access the internet.
Any ideas out there as to the cause/solution?
