Extreme 105 with a SB6120 modem. Have 4 downstream channels and 3 upstream channels.
About once every day or so, one of the channels will drop out, and the modem will only show 3 downstream channels. A reboot of the modem will restore the fourth channel. Additionally, there seem to be a number of correctable and uncorrectable codewords.
Do I need a tech to take a look? Generally the signal has been good and has not fluctuated. Here is a snapshot of the signal values on the modem.
