Please help! i realy want to know, Can i use a Mikrotik Ap- bridge and use a non mikrotik as a CPE i mean something like senao CPE and how will i go about it

Yes you can use a Senao CPE. I set up a 433AH with the R52H card for the AP and used an ECB-3220 in bridge mode. Worked great.

Please what is the distance and which of the senao CPE did you use ?

And how do i configure the senao wireless client device to work with my mikrotik Access Point
