Welcome to the community! Are all devices unable to detect the 5Ghz wireless channel? If so, try to do the following below.
In the event the issue still persists, perform a Factory Reset however by doing this you will have to reconfigure the modem by re-entering TPG username and password also setup the Wireless network both 2.4Ghz and 5Ghz.
Let us know how it will go.
5g shows enabled and connected on the modem interface too, but not showing on wifi list of any devices.
I have been on the nbn home plan since 2019 with both 2.4g and 5g channels working. But recent few months the 5g one often drops out and now it doesn’t appear on devices even if I restart the router. Any chance you know what should I do? Is it a modem issue? Using the archer vr 1600v
Sad to learn that factory reset did not work, send me a Private Message with your account details (Username/Customer ID together with the address on file) also include your best contact number and preferred time. We'll have one of our Technicians to contact you for real-time test and investigation.
Thank you for the instructions. I have tried them including reset to factory settings, which worked for a few hours and now the 5g is dropped out again. So it now shows up on device but cannot be connected. Either with “wifi cannot be found” or “unable to join” error. Tried restart device, forgot the wifi and turn client device wifi on and off, none worked. My multiple devices are effected.
So to sum up, 5g shows up on device wifi sometimes, picked up on wireless scanner, but cannot be connected.
Also the renaming didn’t work, it restarted and comes up with old name. And after disable 2.4g the 5g still cannot be joined.
