Hi I recently bought a TP Link VX420 -G2H off facebook marketplace to use with Aussie Broadband It has firmware  is 2.0.0 0.9 v603c.0 Build 211106 Rel.36845n installed. How do i get the latest "Firmware Version: 2.0.0 0.9 v603c.0 Build 220517 Rel.49186n" for it. Am i out of luck because i am not with TPG?  There is also no Telephony option either under advanced settings to configure it to use my VOIP service for Aussie BB? i have to use a lan conected device from them for it to work.   If anyone cah shed some light that would be great Cheers     ...
