Forwarding vlan to wifi mikrotik, where am I wrong?

Question

Computer networks

Sat down like on an elementary question.
There is mikrotik RB91. Firmware tried 6.34.4 and 6.35.rc48.
eth1 is the master for all other ports. bridge initially does not exist at all.
On ethernet1 come vlan11 and vlan100 tagged from the switch.
If you just hang vlan on the interface and configure the dhcp client, then the DHCP interfaces receive addresses and everything works.
/interface vlan
add interface=ether1 name=vlan11 vlan-id=11
add interface=ether1 name=vlan100 vlan-id=100
The next task is to add vlan11 to wlan1. It would be logical to create a bridge and add vlan10 and wlan1 to this bridge.
/interface bridge
add name=bridge_vlan_11
/interface bridge port
add bridge=bridge_vlan_11 interface=vlan11
add bridge=bridge_vlan_11 interface=wlan1
and configure getting ip via dhcp via bridge_vlan_11
Yes, that's the trouble. as soon as we do manipulation with vlan11, traffic transmission through this interface stops.
If you create a bridge on eth1 and already make a vlan on the bridge, then everything works - but how then to add wifi to this vlan.
The task in the future is to make multissid on different vlan.
In general, this method is described in the manuals, and everywhere I read it, and the logic suggests doing so.
Maybe I'm missing something?

Answer 1

As a result, the problem turned out to be in Mikrotik itself. Forwarding wlan to vlan worked after a complete flashing of the device, via Netinstall
