Re: Connection issues - cable modem

The error log entries do not look good. And there is only a single upstream channel that is locked. Noise on the lines can cause that. First, try power cycling the modem to see if it will range for and lock on to more upstream channels and cleaner downstream channels.

Re: Connection issues - cable modem

I've done that a few times, it didn't help - the overall problem just came back. So where might noise be picked up? External to the house or internal?

Re: Connection issues - cable modem

It could be either. You should get a tech out to investigate. Good luck !
