Need to turn off the 5gz Wifi network and only run the 2.4gz so I can install my security cameras (Zmodo), how do I do this?
You can restore the separation of your 2.4 Ghz and 5 Ghz bands. To do so, you will need to give the two bands separate names, and even separate passwords if you want. Once you have completed that in the xFi portal, you can then connect your computer to this 2.4 Ghz band to install your cameras.
Changing xFi Network Settings:
To access network settings from the xFi web portal, select Network from the top navigation. From the Xfinity xFi app, select Network.
Select Edit next to your WiFi network to update your WiFi name and password or set a WiFi name and password for each radio band (i.e., 2.4 GHz and 5 GHz). You can give each radio band the same name and password to make it easier to remember. Selecting Edit also allows you to change your security settings and choose whether you hide or broadcast your WiFi name.
