The last screenshot looks correct. It just puts it in bridge mode.
Don't know if the antennas are detachable, haven't played with that model before.
Do you have the certs?
Yes I have the certs but will only play with that once I can get it working as the primary wifi for the house.
Battling to get clarity on whether the antenna's are removable some people say yes, some say no, some reviews of Amazon say yes they are but so far nothing concrete
