How do I put my phone on 2g and not 5g
If you have the xFi Pods, they require one SSID and they assign the correct band to the device. I have an old 2.4 iPad and it works just fine with the combined SSID.
You can split them here:
If you do have their pods, and you separate the2.4 and the 5.0 bands, the pods will no longer function.
