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 to their 600 mbps (confirmed on their website) but my in-Orbi app internet speeds still show it unchanged at 270+. I thought using the speediest in the Orbi app gives the 'hard wired' speed from the CM2000, or am I missing something? I will run a computer directly to confirm but I thought going through the app (and not over WiFi) I should be seeing over 600 but it appears to be unchanged. I reset the CM2000 and the Orbi, and even checked for firmware upgrades on the Orbi but still no change. Xfinity customer service is less than useless, and I really don't want to pay Netgear because my '90 days' has lapsed. I mean, I'm not going into 'gig' territory so I thought it should just be an instant upgrade. Thoughts?

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.

https://www.duckware.com/tech/solving-intermittent-cable-modem-issues.htmlWhat 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.
Armtek,
I had the same issue. Went from 300Mbps to the 600Mbps Xfinity offers. Once I did that I ran a speed test (fast.com) directly from the modem to my older pc that still has an ethernet port and got very close to 600 and sometimes above at 605Mbps. But for some reason even with Xfinity diagnostics (unplugging and plugging and resetting modem and router), once the signal leaves the modem and then to the router it is well below 600Mbps. Not even close. Around mid 300's to 400's. So their solution was to RENT one of their Wifi Modems. I'm using a new (AC1900) Netgear R7000 router.
