I seen alot of issues I'm having with CM1100 and RCN
I seen alot of issues I'm having with CM1100 and RCN (Now Astound). My firmware is V7.01.01, currently available is 10.01.07. I asked them to update, they say they don't have the ability to update it, and I need to contact Netgear. We all know its the ISP that needs to request the firmware from Netgear and then update the customers that have. They tell me that maybe they haven't updated it since it's maybe not stable. I told them hu? You mean to tell me in 3 versions (not including subversions) that there isn't a stable one since that? That's just one problem in nutshell. They have no clue what bonded channels are, even supervisors in tech support for internet related help. For some reason, 21-32 down is locked, and 4-8 up are locked. I tried changing start frequency to see if maybe it was provisioned that high to force only 1-20 channels to bond. Everytime I change the frequency, it changes it back to 579 mhz.
I put all images in 1 picture, didn't know could only post 1 pic per post. Hopefully can see and read everything.

Power is all over the place. All channels should be close in power to each other:

You have lots of correctables and un-correctables that should be zeros.
Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem. https://highspeed.tips/docsis-events/
Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.
