Thanks for the reply, I am getting nowhere with Telstra, have lodged a complaint with them and with the TIO, they know the issue, they call it a Jumping fault, as their systems think I'm on Gen 2 modem, but I'm on Gen 3 Modem, so serial number and mac address can't talk back to Telstra, hence why I can't activate internet optimizer or get my land line working. But for some reason no one at Telstra is fixing the issue, they even said they would send me out a new Gen 3 modem but sent a gen 2 instead, they said it would be fixed at their end within 24 - 48 hours, since 15th Dec, it's a joke and a nightmare dealing with their faults service. Now, I know you guys can't do anything, but if @mannrs can advise me with any info on this it would be appreciated.
