For the past few months, my connection has been dropping for six to twelve hours per day almost every day and I can't tell if it's me, Comcast, or something else. We tried customer support, but of course, they diagnosed it as perfectly fine.
I live in south-eastern Pennsylvania, and there's massive SEPTA train construction going on. We live a few blocks away from a station, so we tried asking if this was the culprit but didn't get a straight answer.
The lights look like this when the connection goes out: 'PC' light flickers occasionally (the yellow ethernet cable is always connected correctly), 'Cable' light goes out, and sending/receiving lights flash at the same time.
This leads me to believe it's the construction, but I'm still not sure and I'm getting really sick of this. Is there a way I can diagnose whether or not this is an issue with Lubuntu?
Thanks.
