CM500-100nas amber upstream light - available channels vs number of channels shown
I've tried searching this and haven't seen a direct question or answer to this question, only references. If missed it somewhere else I apologize. My modem is a CM500-100NAS and my ISP is Spectrum. ...
I would ask the ISP how many channels they using for the UP. If they say more than one then possible the modem maybe faulty.
Might ask them as well if there is any FW available from them they could push.Have the ISP check the signals and line up tot the modem to be sure.
Check all cables, connections and coax connectors. Some times connectors can be bad, go bad or not properly made in the first place.
FURRYe38 I'm not trying to be dense but I feel like I am not clarifying the question enough. I'm not asking how many should be used to support my ISP package.
How many of the upstream channels should be visible in the status display?
Regardless of their status, even if they are not required, even if they are not necessary and even if they are not used by the ISP. Should all 4 still be listed when viewing the status?
For instance, in this link you gave me:
the screenshot of the solved message ( 4 of 5 ) shows 4 locked channels and 4 not locked channels. The unlocked are not necessary or used but are still showing as available.
From what the spec sheet says this model modem supports 16 down and 4 up so these should be in the display UI:

Ok cool. Then would that indicate an issue with the actual modem and not with the ISP or the coax or the signal? The troubleshooting portion of the manual shows nothing about channels not showing in the UI and mine only shows 1 upstream channel in the display UI. That said, if after a factory reset the other 3 channels are not visible in the display UI, would that indicate that the modem itself is going out?
