Intermittent disconnects - T3 Timeouts

I'm getting intermittent disconnects and massive speed drops thorughout the day.  I'm trying to isolate between the modem and the incoming wiring.  


I am internet-only, so I have removed all splitters between the incoming wire and my cable modem.   Connections are all snug and nothing looks corroded.


Current signal status:

Current error log:


Modem info:

Model Name: SB6120
Vendor Name: ARRIS Group, Inc. 
Firmware Name: SB_KOMODO-
Boot Version: PSPU-Boot
Hardware Version: 3.0


Any advice for isolating between the two before I spend on a new modem or call in a technician?



Re: Intermittent disconnects - T3 Timeouts

The SNR's are too low / out of spec and the upstream power is on the high end (especially on channel number 3). Seems that there is a line impairment somewhere. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, and latency problems. If there is nothing else that you can do to improve the connection, it may be best to get a tech out for this one !
