I am living in Burwood NSW and using 5G wireless internet. But lately the connection is so poor at certain time like 21:00 - 00:00. It almost freezed. You can't be maintenance every single day aren't you?
I'd like to arrange a callback with our tech team on the specific time that you are experiencing the connection issue, so as to determine as to what is causing it. Send me a PM with your TPG customer ID.
