No Ranging Response received - T3 time-out error
Trying to figure out if I have a potential problem with my Netgear CMD31T modem or if there is a communication problem between the modem and Cox servers. As I expected this problem is way above the heads of Tier 1 support so I thought I'd check in here. My downstream throughput is fine (60M) and I do have upstream throughput that is within parameters (5M). My problem is the modem upstream channel/sync lights show a problem. 1/2 is orange and 3/4 is out. When I get into the modem it shows sync and signal issues: Connection Startup Procedure Procedure Status Comment Acquire Downstream Channel 789000000 Hz Locked Connectivity State OK Operational Boot State OK Operational Configuration File Complete Security Enabled BPI+ Downstream Channel 0 Lock Status Locked Modulation 256 QAM Channel ID 1 Symbol rate 5360537 Downstream Frequency 789000000 Hz Downstream Power 9.3961 dBmV SNR 37.6363 dBmV Correctables 422 Uncorrectables 694 Downstream Channel 1 Lock Status Locked Modulation 256 QAM Channel ID 2 Symbol rate 5360537 Downstream Frequency 783000000 Hz Downstream Power 9.1820 dBmV SNR 37.9359 dBmV Correctables 393 Uncorrectables 1374 Downstream Channel 2 Lock Status Locked Modulation 256 QAM Channel ID 3 Symbol rate 5360537 Downstream Frequency 795000000 Hz Downstream Power 8.6046 dBmV SNR 37.9359 dBmV Correctables 414 Uncorrectables 469 Downstream Channel 3 Lock Status Locked Modulation 256 QAM Channel ID 4 Symbol rate 5360537 Downstream Frequency 801000000 Hz Downstream Power 8.9304 dBmV SNR 38.2578 dBmV Correctables 1644 Uncorrectables 8457 Upstream Channel 0 Lock Status Locked Modulation 64QAM Channel ID 4 Symbol rate 5120 Ksym/sec Upstream Frequency 36700000 Hz Upstream Power 35.7500 dBmV Upstream Channel 1 Lock Status Not Locked Modulation Channel ID 0 Symbol rate 0 Ksym/sec Upstream Frequency 0 Hz Upstream Power 0 dBmV Upstream Channel 2 Lock Status Not Locked Modulation Channel ID 0 Symbol rate 0 Ksym/sec Upstream Frequency 0 Hz Upstream Power 0 dBmV Upstream Channel 3 Lock Status Not Locked Modulation Channel ID 0 Symbol rate 0 Ksym/sec Upstream Frequency 0 Hz Upstream Power 0 dBmV Current System Time:Tue Jan 16 14:34:19 2018 This is a recent error log Tue Jan 2 23:12:32 2018 Critical (3) No Ranging Response received - T3 time-out;CM-MAC=e8:fc:af:ad...

I'm trying to confirm if I've got a modem in a pre fail state. If that is the case, I don't need a truck roll to my site. Advice on next steps? Thanks
