2.4 mhz devices not connecting.

Not seeing any errors. the P?N is CGM4981COM

That is our XB8. By default, the modem tries to find the best connection and does not split the 2.4ghz and 5ghz bands up. You can enable split bands and individually name the 2.4 and 5 connections by following these steps:

1. Log into the Xfinity App

2. At the bottom select the WiFi tab.

3. Click the WiFi details icon. Should look like a network signal icon.

4. Bottom of the page will be Edit WiFi Details.

5. Should have a toggle to turn on split bands and then scoll lower to name each one. 

6. Click Save

You should be able to connect those devices to the individually named 2.4ghz band after that.

Isn't that exactly what was covered in the link I already posted ???.....

I've tried that, split the bands and renamed the 2.4. Neither application will still not connect to the 2.4.

Go ahead and send us a direct message with your full name and service address, and we can dig a little deeper into this issue.
