I have an RT-AC66u hard wired to an Xbox One via the LAN port. When I run a speed test on the Xbox I get a download speeds of 90Mbps. If I plug the Xbox straight into the modem I get speeds of 600Mpbs.
I've tried all of the LAN ports and have tried swapping multiple CAT6 and CAT5e cables between the router and modem, but get the same results regardless.
