CM500-100NAS Upstream Channels Partial Service
SETUP As the subject references, my modem indicates that it is only locking onto one upstream channel (see logs below). Current setup: Netgear CM500 modem Google WiFi (1 primary, 2 non-prim...
thank for you such a clear description and formatting. I wish other users could be like you!
your Signal levels are bad.
for downstream: TONS of Uncorrectables
for upstream: you got partial service and just ONE UPSTREAM channel that is hanging on last leg. It could die anytime
I strongly suggest you to call your ISP and ask them to fix the line.
If you have any splitters or bad cables, remove it
If you have other outlets in your home, try those if they are better.
Who is your ISP?
Is this old home or new build?

also you will see in the event log, modem tried each of the other upstream 16 times and failed to get response from headend. thats why it went into partial service.
vkdelta- thanks for your comments about my post. I just wanted to make the problem as clear as I could.
I have some updates, and some new logs, and a potentially new issue.
Updates
- ISP sent out a technician this morning to "...check outside line connection, installation or replacement of Point-of-Entry filter to boosts signal levels."
- I don't know what the technician actually did, but I can confirm that all four upstream channels are now locking.
- Purely anecdotal, but people are not complaining about my A/V quality today.
New Issue?
- Power levels still seem high on the upstream channels, and there is a new issue with large amounts of correctables/uncorrectables in the downstream channels.
