Intermittent Connection Issues

My home internet connection suffers from heavy connectivity issues without fail everyday in the morning (from like 8 AM - 11 AM). Restarting the modem/router does nothing when this happens, and the connection is too unstable to use until it resolves.

This also occasionally happens outside of the mornings (usually later during the evening, or at night).

A tech came some time last year and found that one of my neighbors had a poor setup that was causing lots of noise for everyone else in the neighborhood. Could it be the same thing happening again?

Modem: Netgear CM1100

These are the CURRENT power levels (while the connection is stable and working fine).

I don't have the power levels at 8-11AM when the network was suffering from issues this morning, but the next time it happens I will try to get a snapshot of those as well.

The logs seem to have some odd entries from 8-11AM though, when the network was suffering from issues.

having multiple disconnects a day for about 1 week now.... lots of 'uncorrectables' also.... so frustrating! I have to take a photo of line today - tree fell a few months ago - took out maybe 3" of the black coating...wonder if that's causing my issues...

Im having the exact same problem with my CM1200 modem. Had it for about 2 months and it worked perfect since new. For that last 2 weeks is when the problems started happening. Netgear techs say its xfinity, xfinity says its my modem. Please keep me in the loop as to what happens! Thanks!

It abosutley is a comcast / xfinity issue otherwise we wouldnt be getting T3-T4 errors. A good friend of mine went a bought 2 brand new modems (different brands) and both of them threw the same error logs within 1 day of use.
