I was tired of the weak little tplink white router TPG gives us with our NBN plan so I upgraded to the TP-Link AX1800. It wasn't as plug and play as expected and a lot of people here seem to be asking the same question.   I have the NBN type that has a cable coming out of the wall connected to the little NBN black box. I then have the ethernet cable from the NBN black box to the WAN port on the AX1800 (the blue one).   This is what you have to do to get it to work.   Plug everything as above, connect to the AX1800 via Wifi or ethernet using the tag underneath the unit and go to http://tplinkwifi.net/ (or 192.168.0.1 , same thing) When they ask you to do the "quick setup", skip it and you should land on the homepage of the router that has 'Network Map', 'Internet', 'Wireless' and 'Advanced' at the top. Got to Advanced Under Network on the left, click on 'Internet'. Set connection type to PPPoE. Enter your tpg username and password (don't forget to add @TPG.com.au after your username). Same details as the ones you use to access your account online. Click Connect. Now go to IPTV/VLAN (on the left). It should be enabled, if not, tick the box. Set the 'Mode' to 'Custom'. This is important, it won't work if you select 'Australian NBN' (you'd think they'd make it easy, right? Nop.). Set your Internet VLAN ID to 2. Set your VoIP VLAN ID to 3. Set your IPTV VLAN ID to 4. Go to 'Wireless'. Set your own network name and password. (Security should be already set to WPA/WPA2-Personal). Don't forget to reconnect your device to your new network once you set that up. That should be it! Thank you.   ... View more
