Problem authenticating with non-Cisco cards to AP running IOS 123-7JA1

[m-avramidis]

After uppgrading our AP 1100 to release 123-7.JA1 our non-cisco (built-in, Intel) cards can`t authenticate to our network. We uses EAP-FAST. Our clients are using the latest release of Intel`s ProSet utility (9.0.30). Also, it does`nt work with manually importing the PAC files. But if i downgrade our AP`s to 123-4, it works without any problems. Is there anybody which have experience a similar problem?

The laptops which we are using are:

Fujitsu - 2200 b/g

HP NC 6000

Dell D600

IBM T42

None of the above laptops with buil-in WLAN cards could authenticate (EAP-FAST, but they could authenticate using LEAP) against our network. We are using ACS 3.3.

Did you make sure that Aironet extensions are disabled on the upgraded version on the Access point. Because the Aironet extensions are enabled by default and hence when the AP is upgraded the new version of the IOS will have this feature enabled. Check on this. EAP - Fast should work in 12.3(7)JA1
