Ok, you have a G.Fast service. G.Fast modems are very few and far between. Easier to stick with the home hub and sell the Asus on Ebay
G.fast same coper wired connection like DSL but with more power comes through.
NETGEAR DM200 Delivers download speeds up to 100 Mbps (with ISP service support) He can't use the DM200 to connect RT-AC5300.
So confused i was hoping to have the asus as a stand alone router modem i can already connect the asus router via eithernet cable just had hoped someone who know away to make my asus one standalone
Google G.Fast modems and see what you can find, they are very few and expensive.
The Asus is just a router so a separate modem is required.
