Multiple modem log Notices

Thank you for the info. What exactly could be causing that? Everything is brand new. 

Something upstream from your house. Could be a bad overhead or buried cable. Could be a bad amplifier somewhere. Could be a neighbor backfeeding noise. If all of your equipment is new and working properly there's nothing you need to do. Like I said it's not causing issues until it starts to affect profile 1 or 0. It's to Cox's advantage to have everyone on profile 3 since that provides for maximum bandwidth so maybe they'll look into the problem at some point.

The only thing that has changed in the last 2 weeks is we've made the transition to 5 upstream bonded channels as opposed to 4.

That's the only thing you can see. But anything in the plant could have changed. Parts are being replaced all the time and any part can go bad at any time. You won't be able to figure out the root cause of those messages. It's just impossible for a customer to be able to do that.

You should post a new thread and show your modem signals and logs. Unless you live on the same block as the original poster it's likely a completely different issue even if the symptoms are the same.

And here I was thinking this way my post.... Lol

Cox shouldn't connect to your router.  Cox should only see your modem because only the modem is on their network.

What specific issue are you having?  What do you have for a device:  modem/router combo?
