Hi I’ve had NBN with you guys for a couple of months now, with both the 2.4GHz and the 5GHz connections running fine, but all of a sudden the 5Ghz won’t let me connect to it any more saying that it’s an incorrect password but I’ve used the same password on the modem and I haven’t changed it at all. And there is another person using this connection with no problem. What can I do to be able to connect to the 5G again?
Welcome to TPG Community!
Have you tried forgetting the network and reconnecting the device to the network using the old password?
You may also change the WI-FI password and reconnect all the devices to the WI-FI network.
