@NHluhr, The modem is reporting some poor signals on your upstream channels. Are there any splitters or signal amps on the cable line going to the modem? -Allan, Cox Support Forums Moderator.

No, the cable comes from the pole at the street to a springy looking physical attachment on the side of my house, and then runs to a penetration in the wall, sealed with silicone, and straight to the back of the modem without any splitters or junctions.  When I moved to this house ~6.5 yr ago, there were multiple junctions spreading the coax to other parts of the house but we removed all those and ran the cable direct.

On the upstream channels, the power readings are all 29-30 dBmV but my side doesn't show much else (like SNR) for upstream.
