I have the Netgear Nighhawk R7000p and it works fine on TPG HFC NBN through ARRIS CM8200 NBN box.   Remember that the boxes for the Nighthawk are nearly identical between the R model and D model. You have to look for the model number. I could not get the D model to work on HFC NBN as it doesnt have a proper WAN connection for the ARRIS box.   This is what I did straight out of the box to get the R7000p working:   Step 1 - Disconnect the Archer TPG box completely (you dont need it at all). Connect WAN cable from Nighthawk direct to Arris box, run an ethernet cable from Nighthawk LAN (any port) to your computer. Reboot both boxes to start (arris first/then router). Call TPG and let them know you are going to use a 3rd party router. They can at least make sure there are no settings at their end that will block your connection Step 2 - Open a browser and go to nighhawk settings via routerlogin.net directions for your router. Otherwise type in 192.168.1.1 and input admin/admin as username and password if asked Step3 - Dont use the wizard setup. Use the manual configure option when you first start. You will go to a standard netgear genie page with a basic tab and advanced tab on the top and a menu on the side with internet, wireless, parental control etc.. Step 4 - Go into "internet" on the basic tab and make sure the following is added: a. Does your Internet connection require a login - "Yes" b. Internet Service Provider - "PPP0E" c. Login/Password - Input your TPG supplied login username and password d. Connection mode - make sure the drop down is "Always on" then Hit apply..the router will update settings for a minute or so Step 5 - Go into the "advanced" tab on the top of the page.Then select "advanced setup" on the left hand side. It will open a menu below it. Scroll to the entry that say "VLAN/Bridge settings". Click on it. It will open a new page . Check the box that says "enable VLAN / bridge setup" and select the 2nd option "by VLAN tag group". Cick "+add" and a new page will open with "Add VLAN rule" across the top. In the three boxes underneath add teh following: 1. Name - "Internet" 2. VLANID - "2" 3. Priority - "0" then click "+/add". It will take you back a page where you hit "apply" and again teh router will update settings and most likley boot you out   The router will apply the settings, it will either reboot itself or you might have to reboot both the arris and night hawk router manually again...   But with those settings when you switch back on you will find the internet connection light pops up and your away and working fine.....   now if only someone could solve Foxtel IQ3 connection issues...foxtel...it really isnt good enough!!    ...
