RouterOS v3 Configuration and User Guide
On the AP in default or in your own made profile as an encryption algorithm choose wpa-psk. Specify
the pre-shared-key, wpa-unicast-ciphers and wpa-group-cipher

On the Client do the same. Encryption algorithm, wpa-group-cipher and pre-shared-key must be the
same as specified on AP, wpa-unicast-cipher must be one of the ciphers supported by Access Point

4.3.22 Troubleshooting
Description
If I use WDS and DFS, the routers do not connect to each other!
As the WDS routers must operate at the same frequency, it is very probable that DFS will not select the
frequency that is used by the peer router.
RouterOS does not send any traffic through Cisco Wireless Access Point or Wireless Bridge
If you use CISCO/Aironet Wireless Ethernet Bridge or Access Point, you should set the
Configuration/Radio/I80211/Extended (Allow proprietary extensions) to off, and the
Configuration/Radio/I80211/Extended/Encapsulation (Default encapsulation method) to RFC1042. If left
to the default on and 802.1H, respectively, you won't be able to pass traffic through the bridge.
