Asus RT-AC68R slow wired speeds

[AzNBoY92]

Well just got a new Asus RT-AC68R from Best Buy and everything works better from then the AC66U, 2.4 speeds are faster and wired and 5 ghz are same, but for some reason the only problem I'm having is speeds on my Xbox One wired so significantly down from the AC66U. The AC68R is outputting only 18-20 Mbps for the Xbox One while the AC66U was outputting 50-57 Mbps which is what I'm paying for. My laptop wired is showing up 50-57 Mbps on SpeedTest. What could be the problem? I have latest Merlin firmware.

Have you tried other Asus OEM firmwares?

Have you tried a different cable?

Have you done a full reset after each firmware upgrade?

Noticed the same thing on my PS4 as well.
