WPA2-PSK AES on 1231G

Unanswered Question

I was hoping to get some assistance on getting the 1231g to work with WPA2-PSK (AES).  My laptops cannot authenticate using this config but connect fine to the 1242AG.  Below are some of the specifics:


1231G

Radio Type: AIR-MP31G

IOS Ver: 12.3(8) JED

Multiple SSID

Encryption: AES

Key Management: Mandatory WPA


*Laptops can connect to SSID with WEP


Any help would be greatly appreciated.

  • Cisco Employee,
I am sorry to say this, but in order to do AES with the AP you are using, you MUST have
either an AIR-RM21A or AIR-RM22A...this ap does not have either one of these radios. 

...the following excerpt is from the 12.3(2)JA release notes:

AES-CCMP

This feature supports Advanced Encryption Standard-Counter Mode with Cipher Block Chaining
Message Authentication Code Protocol (AES-CCMP). AES-CCMP is required for Wi-Fi Protected
Access 2 (WPA2) and IEEE 802.11i wireless LAN security. This feature is not supported on
350 series access points.

This feature is supported on these devices:

•1100 series access points (802.11g radio only)

•1130AG series access points

•1200 series access points (IEEE 802.11g and 802.11a radios only with the part numbers
AIR-RM21A or AIR-RM22A)

•1230AG series access points (IEEE 802.11g and 802.11a radios only with the part numbers
AIR-RM21A or AIR-RM22A)

Rating the resolution is really appreciated.

Version dependent perhaps? This museum piece supports it
