Virtual AP using Prism b only card

I cann’t seem to get VirtualAP to work using the Prism card. I have it working using Artheros AR5212.

Has anyone else see this or have it working.

Help!

it does not work with Prism.

Were did you find out this info from? any documention? or just tring it out?

from Mikrotik RouterOS manual:

Virtual Access Point Interface
Home menu level: /interface wireless
Description
Virtual Access Point (VAP) interface is used to have an additional AP. You can create a new AP
with different ssid. It can be compared with a VLAN where the ssid from VAP is the VLAN tag
and the hardware interface is the VLAN switch.
Note that you cannot use the Virtual Access Point on Prism based cards!
