You mentioned you live in a apartment and your signal levels look on the high side. Can you describe how the coaxial gets from the street to the room the modem is in? Does it go through some maintenance room or amp before getting to your apartment?
Also, what do the logs say? Be sure to edit out the CM MAC address from the logs if you post them.
Cable runs up and into small attic space above apartment units, then back down the other side and into the cox box street-side. Nothing in that routing changed since the issues started.
If it helps, I've lived in two different units in this complex, they've both used that setup, and this is the first time I've experienced issues.
Requested log is below. Only have a ~day of activity on this modem since it was reactivated.
Looks like noise on the upstream and downstream. I suggest another technician or someone to check the line in the attic. Or at the very least isolate if the problem is happening at the demarc in the Cox box. Can you move your modem out there with a power cord for a little bit?
