High Disconnect Rate
I've been having intermittent disconnection issues starting about 5 days ago. I've done what I can as far as basic troubleshooting is concerned (rebooting devices, checking cables, etc.), yet the issue remains.
Currently using a SurfBoard SB6141 Cable Modem and Asus router. I've checked the logs on the modem and found this error show up each time the internet drops:
No Ranging Response received - T3 time-out;
The SNR on each channel ranges from 36 dB to 39 dB.
Upstream Power levels are at a steady 46 dBmV to 47 dBmV.
I feel like I've ruled out everything except the modem itself being defective. Unfortunately I do not have another modem to test out at this time without purchasing a new one. What should my next step be here?
