CM1000-1AZNAS xfinity / download speed issues
Hello all, I am posting here because I am at my wits end with this problem. I have a CM1000 (owned for several years) that has recently started acting up. I pay for the xfinity giga (1200Mbps) se...
The CM1000 is a modem only. Netgear says it is good for 800 Mbps on Xfinity.
What router do you have between your CM1000 and your main wired PC?
What version of firmware is installed on your CM1000?
Netgear says it should be V7.01.01 for Xfinity.
Your signal strength (power) levels do not look out of line.
The CM100 is a modem only and according to xfinity should be good up to 927 Mbps. Which I would be happier if I was reliably seeing either of these speeds.
All testing is done wired from modem to PC, while I do have a netgear nighthawk router it is only in use for the house hold use. I disconnect when chasing down issues.
Firmware version on my modem is V7.01.01

The tech's hardware indicated everything was fine at the modem. Maybe you should be looking at your main wired PC? Mac or Windows (version 10 or 11)?
If it is Windows, you get updates every two to four weeks from Microsoft that could adversely impact your network settings.
Network profile, Private or Public? IPv6 enabled on your router?
Windows 7 ultimate (64 bit) service pack 1&2.
Home network with IPv6 enabled but not being used.
