Hi @LucyJuler . What type of NBN connection do you have?
Are you on bundled NBN/VOIP plan or a BYO data-only plan?
@LucyJuler . If your TPG router connected directly to a telephone wall socket, you have FTTB or FTTN.
A small black NBN box means HFC. A small white NBN box means FTTC. A bundled NBN/VOIP plan with these 4 connection types need VLAN ID setting which is not available on Gen2 router.
The other connection type is FTTP. With this type or a BYO data-only plan, the Gen2 should be suitable.
Do factory reset. Settings are PPPoE, username + @tpg.com.au and password.
Any brand-name router would be better in short term.
@LucyJuler . Another post in Community says the Gen2 doesn't support VLAN ID setting so it won't work with FTTN.
(To reset, push a paper clip in the hole next to USB socket for 10 seconds.
In the menu system, select Broadband, Connection Settings. Type=PPPoE.)
Regarding the TPG router that stopped working, was it total failure or partial? Like, maybe, just the wifi stopped working?
