For FTTN connection... You can follow the TPG TP-Link Archer VR900 FTTN instructions   The VR2100 has the same settings as the VR900, but goes through a setup wizard. A couple of things to save some headaches for connecting TP-Link Archer VR2100 to NBN FTTN... a) connect from the wall socket to the DSL port on the router (just like the VR900) b) When prompted for your 'internet service provider' (ISP) scroll down to find the  'TPG' one. c) When asked for your 'ISP/TPG username and password', the username is your login username but make sure to include '@TPG.com.au' after it e.g. 'username@TPG.com.au'. d) if your TPG plan is a 'NBN FTTN/N bundle plan' at the end of the setup wizzard, it will fail it's internet connection test.  To fix this, change the settings on the 'Basic,Internet tabs' to that in the attached image... and save. (You can find what plan you have by login into your tpg account and select 'plan and contract details'.) Hope this helps others.    ... View more
