Optik Wireless Box, default to wired instead of wireless

[wireless]

Hello there, I have two Wireless Boxes and one access point.
I managed to activate them using the pairing with the access point and then once activated/paired, insert the RJ45, this allows them to work properly.....until power goes off, then I have plug back the access point and redo the pairing.
I know I shouldn't have chosen the wireless box since I do have a great network in every room but Im wondering if there is some hidden menu to select Wired/RJ45 connection as default instead of the wireless.

Any help is really appreciated
