@SciGhost You can try the following Disable Easymesh feature and check again your connections. If this connection still exists then probably some other device is connected to your Asus router.

@tp_gandhar Your best bet is to contact your local support regarding this issue - details.

@TwoSocks You can power up EAP625-outdoor with a passive PoE adapter on 48v as well and skip buying a PoE switch:

@Dan-_ If you've set your printer with a static IP address, try setting it to receive its IP address via DHCP (automatically). I believe then you should be able to see the printer in the router...

@Cyprus_Phil Your observation is correct. When in AP mode the RE can't use its mesh feature. But you can always set the RE (in AP mode) to have the same SSID as your mesh network. Another approach...

@Spawn_e_git At the moment probably the best approach would be to use another AX1800 inside a plastic box. You may even skip the box drilling for the antennas - plastic won't work as a Faraday cage....
