I was testing this on an existing network and the wireless 5g was interfering with my existing wifi 5g.  Bands were overlapping.  I need to figure that out as well since it doesn't appear that the Archer lets you edit the wireless bands used.   The Archer was correctly getting an IP and Gateway info from DHCP.  Connecting to the Archer from wireless devices worked fine (IP correctly assigned from upstream DHCP and internet access working).   When I physically plugged into the LAN ports on the Archer I was not getting assigned an AP from DHCP even when attempting an ipconfig /RELEASE - /RENEW.   nothing I plug into LAN is working and they are using cables that I used testing switches, hubs, firewalls and the router.   It doesn't say that LAN ports are not supported but if you carefully look at the graphic pictures on the Archers MODE menu you'll notice that in Router mode they show a line from the LAN ports to a device.  In the Access Point graphic they only show a device using wireless, the line from the LAN ports to a remote device is removed.   But they don't actually say it isn't supported.   I can't test right now because of the wifi conflict with existing Access point and Extenders.  My goal was to replace my current Netgear running as an Access Point with the TPLINK but I need to know if I have to add a hub/switch to make up for the lost ports if I can't use the Archer LAN ports.
