Somebody Knows why RB600, running in WDS mode and using "Conect List" to authenticate, doesn´t work with airgrid (or similar with AIROS).
Each time that mark "Default Authenticate" in Wireless menu , it works.
Thanks in advance.

Which WDS-mode are you running on MikroTik?
Perhaps Access-List configuration is necessary on your router.

I´m running Static WDS and I´ve setup the rigth WDS client´s MAC at Conect List menu. Other manufactures like AIRLIVE are working well.
