Aironet 1131AG WPA Configured. Drops Mac OS X Users

Unanswered Question


Cisco Aironet 1131AG

I recently changed my authentication type to WPA2.  When Mac OS X clients attempt to join the wifi network, they'll be assigned an IP address from my DHCP server, but shortly after, the Aironet will drop them.  I've tried giving them a static IP, but then they can't access out network servers.

I have no issues w/ iPhones or Windows based machines.  Any ideas?

Encryption Manager:

Ciper - AES CCMP

SSID Manager:


Open Authentication Checked w/ no additions

Key Management: Mandatory

Enable WPA checked and selected WPA from the drop down

I have also seen this issue in an LWAPP/CAPWAPP environment, but usually when they have both WPA & WPA2 being used.  From the CLI of the AP, can you set the WPA version to 2?  You can try this command in the CLI and set it higher than default of 100ms: dot11 wpa handshake timeout

Try setting the Mac OS X users to WPA/TKIP or WPA/AES and see if that works.... if so, then you know that the AP is allowing either and that is your problem.
