Hi @Snag . The unit is quite old now. It looks like it might be ok but the manual is unclear if it supports VLAN ID when using the ethernet interface to connect to a NBN box (FTTC or HFC).
A FTTP NBN connection doesn't use VLAN ID. A BYO router data only plan doesn't use VLAN ID. The unit might be ok in these two circumstances.
It only has the 2.4Ghz wifi band instead of the second 5Ghz band on modern routers.
Its ethernet ports are 10/100 Mbps instead of gigabit ports.
It has a VOIP phone connector but it won't work with TPGs voip service.
Looks to have standard features of other models.
Performance-wise, ok for your plan speed.
Nevertheless, TPG wouldn't have tested it because it is an old unit and probably no longer available.
