CM1100 need to reset modem constantly with COX
Hi all, used to be every few days but now I am having to reset the modem multiple times a day and it is driving me nuts. Here is the connection after a factory reset. Many thanks! Startup P...
Looks good. Some channels are a bit far in power between the channels however if it's working. Let it run.
The levels are also all over the place. They should be within 3.5dbmv of each other.
Something is squirrelly with the line.
Thank you all for the reply. Cox tech came out this morning, he said the cable from the outside to the house needs to be replaced (he measured and said there is a 90% power drop).
He said to take care of this first and if issue still occur afterward than he can add a new cable from my house to where the modem is located.
Will report back and share the new connection status once the cable is replaced.
That should help as well the the correctables and un-correctables as those should be zeros across the board.
Also have the tech check the modems events logs. Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem.

Sounds like a worthwhile tech visit. If your internal wiring, splitters, and etc. are more than a half dozen years old, it would be worthwhile to push to have that also replaced.
Cox said it will take up to 12 weeks to replace the outside line (need city permit) but funny thing happened yesterday, ATT Fiber crew outside digging holes to install fiber cables and they severed my Cox line. Spent a few hours tried to reconnect the cables but the hack job failed so today they replaced the outside line. Here is the new connection status:

Some channels are a bit too high. Something you can try get a -6Dbm coax line attenuator in put behind the modem and see if this gets the power down for those channes.
Correctables and Un-currectables are way better though.
