Dot11Radio0 stuck in reset status after changing the station role

Question

Hi Everyone.
I've got a AIR-AP1231G-A-K9 router. IOS has been upgraded to the latest version c1200-k9w7-mx.123-8.JED. Everything worked fine before I change the station role from root to repeater or workgroup bridge. Following is my configuration:
ap#sh run

Then I changed the station role

ap(config-if)#station-role repeater
ap(config-if)#end
ap#sh ip int brie

Interface Dot11Radio0 stuck in reset. No matter I reload or powercycle the AP, I still get the same reset status on Dot11Radio0.
Please help! Any input will be appreciated.

In order to get either the repeater or the workgroup bridge functionality working, you would likely need to have a Cisco AP as root. This is because the repeater and workgroup-bridge functionalities require Cisco Aironet Information Element (IE), which requires a Cisco root AP. There is no standard for interoperability for these functionalities (not part of any 802.11 standards). You can always try to connect them, making sure that they are using the same authentication/encryption configuration. However, it is unlikely to work.
