I have found this thread, but this is not what i want to do. I am obviously new to mikrotik.

I followed tutorial bellow and one other from net that was clicky not typey but have failed as it did not connect, and I did not insert wireless network password anywhere:

So I have Tp Link C2 connected wirelessly to ISPs ZyXEL. I just enabled WDS bridging, inserted MAC and network password of ZyXEL and it worked, just like that.
I would like to connect MikroTik in same way but I have not been able to do this. I am using different SSIDs if that is relevant.
Just to note this is only temporary solution until rest of my equipment and stuff arrives and electrician/cable guy comes to spread cables around.
