WDS get lost in ports of the brigde

RouterOS Wireless Networking

Hello All
I have a transparent brigde 2 networks with RB411A
like this http://wiki.mikrotik.com/wiki/Transparently_Bridge_two_Networks
but every morning when i check my equipment on AP side, i see that the WDS in ports of the brigde is UNKNOWN, only work the ether either wlan but WDS NOT and I have to disable and enable WDS on ports of the brigde and suddenly begins to work.


I suppose when the link is established automatically all ports of the brigde (Ether,Wlan and WDS) must begin to work, right???

Thanks
