Current setup is a Asus DSL-Ac68u router (was on VDSL) this is now reconfigured and using port 4 as a WAN port. Speed tests are only getting 400Mbs and should reach 700-900.
Would swapping to a RT-AC68u help? Does the DSL side limit these routers? Should I get a different brand router? This router is not doing Wifi and both radios are off. I do like the Asus routers.
