Can you give us the configs of both sides? Because WDS is for both manufacturers a proprietary extension which is not compatible with the other. You probably have done something so WDS is not really working. But if state it is you have to show us your configs so we all can learn…
Well, any brand station will connect to Mikrotik AP-bridge. The fact Dynamic/Static WDS is enabled in AP does not necessarily mean the station is accept as station-wds.
The only way to see if the station-wds indeed is bridged as wds station is to see if node 'behind´ the bridge station-wds can be reached from AP in the same domain/network.
Only if you can show me this I (and MT!) will believe you…
Why don’t you just try it and see be yourself?
It works for me, i have several clients with PPPoE connections and small base station attached behind that NS5…
