Hi there. I have purefiber and I can’t seem to get my fire tv units to connect to 5G. I can see other 5G connections from the houses around me, but when I select my 5G connection the network setting says out of range. My modem is literally under the living room, and I still cannot connect to 5G.
Firestick only supports WPA1-PSK, WEP, and WPA-PSK encryption. Make sure your 5ghz channel on your modem is set between channel 36-48 on the 5ghz band. See if that works for you after rebooting the device.
