I have the same problem. I have had a technician out twice & they replace the line but never replace the modem. Once they are finished doing what they think they need to do & check for service it works....then it goes down a few hours after they leave. My internet goes down at least once a day. Sometimes it comes back up & sometimes I have to go through the entire trouble shooting directions before it comes back. Seriously tired of poor internet but it seems country living doesn't have a choice.
