802.11 Association Lost with Cisco AP* Configured for World-Mode Legacy


Clients are unable to associate or maintain association with Cisco Aironet* Access Points.

This issue is intermittent. Sometimes clients briefly connect before losing the connection, but then have trouble reconnecting.

This issue is network dependent. Some lower traffic networks may not exhibit the issue.


This issue is caused by a Cisco Aironet Access Point that is configured with the world-mode legacy command. This command is not supported by actively supported Intel® wireless adapters.


To resolve this issue, disable World Mode or use the World-mode dot11d country indoor command on all Cisco Aironet Access Points.

Further information can be found in this field notice from Cisco*:
FN - 62283 - "World-Mode Legacy" Command is Only Useful for Cisco Aironet 350/CB20 NICs With Earlier Software Versions*.
