How do I manage Wi-Fi connections on my new Xfinity CGM4981COM model router?

I just got and installed a new model CGM4981COM router from Xfinity.  WiFi now does not work with some of my 2.4G devices.  The suggested solution is to have a separate network name for 2.4G channel, but neither the admin gateway nor the Xfinity app will let me do this.  There is a message in gateway admin that these settings are now managed automatically. Any suggestions?

That's the question isn't it?

Xfinity won't publish a manual, or the specifications, or firmware release notes, so it's pretty though to tell what it's supposed to do.  Can an 802.11ax chip set be backwards compatible with 802.11 b?  Sure, according to the spec.  Does the firmware allow it or is it even implemented on the technicolor now?  Shhhh.  They ain't sayin'

You haven't be able to set "radio modes" locally from a web interface for a while now after a firmware push that disabled the local interface.  You "might" be able to with the phone app, but that's also a big IF that is dependent on firmware, and hardware there isn't documentation for.

So how can you make it work?  You could buy an 802.11 b/g/n access point.  You could get a 3rd party gateway with multiple radios in it.  You could just get a straight modem and use a mesh network that can do it.  But whatever you do, don't buy anything without a manual that can tell you what it can actually do, and how it works.

Hello @user_59767f! Are you specifically in the Xfinity App(Purple and white border around the X)? Please log in and click the "Connect" button at the bottom of the screen. Select your network name and then "View or edit Wi-Fi settings. On the next screen, you should be able to toggle on the Split bands button. One enabled scroll up to edit the bands. Please let me know if this already matches the steps you've taken to rename the 2.4 GHz band.

Yes, I was able to follow your description, and this fixed my problem.  I'd be a happier customer if I had not spent MANY hour working with support to install the new modem you sent (the first attempt took my phone and internet offline making the install instruction in the app inaccessible) and then resolving this incompatibility with my SimpliSafe cameras.  Hours on the chat line yielded no workable solution.  Xfinity was supposed to call to set up an appointment with a tech.  I've heard nothing yet. If your "upgrade" breaks my network, Xfinity should fix it promptly.

I appreciate your help.  Next problem, I will come straight to this forum.
