Nighthawk CM2000 not allowing speed upgrade on XFINITY
Back in January 2022 we moved to a new home and I upgraded to a Nighthawk CM2000-100NAS connected to an Orbi AX6000 using Xfinity internet (270 mbps) and had very few problems. Recently we upgraded t...
Please post a copy and paste of the modems connection status page.
Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended.
Connect one wired PC to the CM modem. Power OFF the modem for 1 minute then back ON. Speed test. What are your results here?
Has a power off for 1 minute then back ON with the ISP modem and router been performed since last update?
Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on the router and wait 2 minutes for it to connect.
Turn on computers and rest of network.
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.
Be sure to power OFF the modem for 1 minute then back ON.

What Firmware version is currently loaded on the Orbi system?
When Xfinity installed the service back in January, he did some questionable routing through a splitter that I was going to 'reroute' when I had time, but as it worked OK I was less motivated. I guess I have the motivation now...I've done the shutdown and startup as you've identified. Right now, aside from the Orbi, the only direct wire is for my VOIP (all other is WiFi). I'll eliminate the splitter and reroute the cable directly to the router. Also was using the ethernet cable provided but I guess I can update that as well. I am remote right now and have no access to the Modem page.
Firmware on Orbi is V4.6.8.2 which the app says is the latest.
I know its a PITA but try directly connecting a pc/laptop to the modem and speedtesting directly off there. its good to figure out if the modem is actually the bottleneck or if the routers settings are causing it.
Please post the requested information when you get time and definitely try a power cycle on the modem and RBR or direct speed test with a PC at the modem with out the RBR connected.
