WiFi is not easy. Especially for 1km long link in crowded area. For 110% there are interferences from other WiFi networks so you have to find yourself the best mix of TX-power, channel and channel width. And be prepared to calibrate these settings from time to time ... not to say: often or permanent...

Re: cAP ac bridge ethernet interfaces

Bridge is used in Mikrotik's world as substitute name for "logical/virtual switch".
You can "glue " with it different interfaces as they are all part of a logical switch even if you mix PPoE, VLAN, WIFI, bond and any other kind of interface in Mikrotik.
