Supported MB8611 Modem Downstream
I am using the model mentioned for my cable internet connection.
Recently I have had issues with the downstream indicator lite beginning to flash and causing the connection to become unstable for a brief amount of time.
The only way to get the downstream arrow to stay solid blue is to reboot the modem.
This has only recently become an issue ~last two days. I have had no other issues with connectivity prior to that with this modem. There have been no changes to physical connections in the house or outside the house that is part of my client connection to Cox.
Any "maintenance" or changes in the area by Cox I am unaware of, as is typical to not inform customers of "maintenance".
I have the following connection details for the modem:
•Channels 1, 19, 20, 21, 22, 23 have slightly negative power levels (-1.3 to -0.3 dBmV) but should still be within acceptable.
•All channels have SNR values well above 35 dB.
•High number of corrected errors on some channels
Below are logs from the modem during some of these occasions:
