Has anyone successfully connected their ASUS RT-AC86U with FibreX? I have a static IP address, but apparently with FibreX we still have to chose the DHCP (or Automatic IP address on AC86U) option.
Found the answer!
Just follow the instructions on this link (https://www.asus.com/us/support/FAQ/1034366/) and this link (http://help.vodafone.co.nz/app/answers/detail/a_id/5239/~/network-settings-for-your-broadband-modem).
Thank you for posting an update! Hopefully this will help someone else in future.
