nbn™ has finally arrived! In preparation for this I decided to purchase a TP-Link WD9977 VDSL modem/router to place in bridge mode and use with my existing Billion 7800VDOX router — in this post I’m going to share the steps needed to setup the WD9977 in bridge mode and use my existing router for all other network tasks:

  • Disable wireless network on TP-Link WD9977
  • Disable DHCP server on WD9977
  • Configure DSL modulation settings on WD9977
  • Place WD9977 into bridge mode
  • Configure WAN port on Billion 7800VDOX

Step 1 – Configure TP-Link WD9977

  1. Factory reset the TP-Link WD9977, set a new password on the device once the factory reset has completed.
  2. Select the ‘Quick Setup’ tab, select ‘Other’ from the ‘ISP List’, click ‘Next’.
  3. Quick Setup > Internet Setup.
    • L2 Interface Type: VDSL
    • VLAN: Uncheck VLAN ID
    • MER: Uncheck Enable
    • Connection Type: Bridge

  4. Quick Setup > Wireless Settings.
    • Wireless Network (2.4GHz): Uncheck Enable

  5. Select ‘I am using a wired connection.’, click ‘Next’ to continue.
  6. Quick Setup > Summary. Click ‘Finish’ to continue.
    • Connection Type: Bridge
    • Connection Status: Connected
    • Wireless Network (2.4GHz): Disabled

  7. Advanced > Network > DSL Settings.
    • DSL Modulation Type: VDSL2
    • Annex Type: Annex A
    • Bit Swap: Check Enable
    • SRA: Uncheck Enable

  8. Advanced > Network > LAN Settings.
    • IP Address: e.g. 192.168.0.1
    • Subnet Mask: e.g. 255.255.255.0
    • DHCP: Uncheck Enable

    Set the IP information accordingly, if you need to make future adjustments on the WD9977 you will need to connect to a spare LAN port on the WD9977 and create a static IP connection on the same network.

    I use 192.168.0.x addresses on the WD9977 and 192.168.1.x addresses on the 7800VDOX.

  9. Advanced > System Tools > Time Settings.
    Adjust your time settings accordingly, click ‘Save’.
  10. Configuration completed on the WD9977, proceed to the Billion 7800VDOX.

Step 2 – Configure Billion 7800VDOX

  1. Configuration > WAN > WAN Service.
    • WAN Port: Ethernet
    • Type: IP over Ethernet
    • Description: e.g. Enter your ISP name
    • Available Routed WAN interfaces: Ensure ipoe_eth0/eth0.1 is in this list.

  2. Click ‘Next’, configuration completed on the 7800VDOX.
