Wireless AP client bridging ethernet clients.

I have a situation:
Mikrotik 2.8.9 AP with atheros card 2.4 GHz band.

The ATMEL wireless client is connected to AP (wireless side) and is also connected to local network (ethernet side).

The only IP address seen from Mikrotik side is ATMEL radio IP. No clients behind ATMEL is seen.

Any ideas how to connect ethernet clients to AP without replacing ATMEL radio with another Mikrotik device ?

I have successfully tested WDS configuration betwen MT 2.8.6 ( ap-bridge mode with prism card ) and Linksys WAP11 v2.6 fw1.07( bridge P-t-P mode ).
