Adding a 2.4 ghz wifi

[Mcfeely1]

Idk why I don’t just call for things, but with my old modem, my brother made it so I could connect with either 2.4 or 5. Each had its own password. My weather unit has to use 2.4.

Can you tell me how I can create a new 2.4 network and keep my 5 ghz also. I want to choose and not have it auto connect for me.

Thank you...

The two WiFi bands have recently been combined into one with the Comcast gateway devices. Some devices get confused and don't know how to see / talk to combined bands.

If you are not using any Xfi Pods, you can try separating the 2.4 and the 5.0 bands and give them two different broadcast names / SSID's;

Associate the weather device with the 2.4 band's SSID (broadcast name) and password.
