Re: momentary internet issues-help. Everyone has "constant activity on the link L.E.D" even if the connection is not in use.
You could run a (continuous) ping -t to your gateway IP via a minimized command box. If you are there when connectivity drops, bring up the command box and see if packets are being dropped.
I don't know if Comcast would object to a continuous ping, even if they noticed.
I have done something similar:
My router is actually a dual-wan device, but I only have one internet connection. There for a while I did turn on "connectivity check" and extended logging in the router. I set the connectivity check to ping the gateway every 10 or 15 seconds IIRC.
I would have several entries per day where the connectivity check failed, and the router declared WAN1 connection dead. 10 seconds later in the log were entries where the WAN connection was declared active again. After the problem seemed to clear for a while I turned it back off.
