Dot11Radio0 stuck in reset status after changing the station role

[robert.huang]

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

FastEthernet0 unassigned YES NVRAM up down

ap#

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.

When an access point is configured to bridge or act as a repeater, it's interface will go into "reset" mode until it associates with the root. Can you post your root AP configuration?

[robert.huang]

Thank you for your reply.

My root AP is a DD-WRT home router. SSID is Lanyard with WPA2/AES encryption. Signal is excellent since it is only 10 feet away.

I know my AIR-AP1231G-A-K9 doesn't support WPA2, only supports WEP and WPA. Is that the reason it can't associates with the root? Do I need to configure authentication and encryption on the repeater?

[JASON BOYERS · Accepted solution]

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.
