Why does my modem continueously disconnects?

Hello again to the Community. I have been receiving massive issues evolving with my cable internet. Daily my modem would disconnect several times, either the situation receiving or sending transmission. It’s nearly impossible to pin point the time of disconnection, however it’s certain that it will happen 3 or more times in a single day. Whether the computer’s on or when I sleep it still happens… So even with inactivity it still occurs.

How do I fix this I tried consoling:rolleyes: with my ISP “Charter Communication” and they still haven’t found the situation so please help me.

Here’s my modem Motororola SB5101 Cable Modem log:

Either the modem needs to be replaced, or there is a problem with your line. Maybe both, impossible to say from here.

Get a technician to your house to check the line. You pay for the service, demand they fix the problem.

I had the same problem till the cable company replaced my modem and I replaced my wireless router. The modem was outdated and the router was going south.
