My past experience is that I just have to sit and wait for connection to return.
The "internet" light on modem blinks..and blinks ..and blinks.
then..pc link light will start blinking..
then all the lights will start blinking and VOILA I am back on the internet.
I will lose my internet and will give up the ghost for the evening.
I will go to sleep leaving the pc link light blinking and blinking and blinking....
wake up in middle of night and I see activity on modem...internet coming back.....
This has happened before but only once in a great while.
This time around it has been happening every day ...the past four days.
No internet for hours and hours....all night.
then ...lights will start blinking and I have internet back....
just got back on about thirty minutes ago
I think it is Comcast issue....something at their end...but I don't know what.
Comcast seems determined to either send out a technician or to try to sell me phone service.
But when calling customer service it is the same old drill...secure power from modem etc
