T61 wireless 11 a/b/g/n PAC pops up for every restart

[txops]

Greetings everyone.
We have created a wireless network in our company. We use EAP Cisco (EAP-FAST) security with AES encryption. We got a variety of Thinkpads with different Wireless Network card, ranging from CISCO, to Intel to the IBM 11 a/b/g and 11 a/b/g/n
Everytime we try to connect to the Access Point with our T61 (11 a/b/g/n), we are prompted to accept a new PAC.
This behaviour is exclusive of this driver, as it doesn't seem to happen with CISCO, Intel or the 11 a/b/g driver we use in other machines when You might be prompted once, but not every single time. We are using the latest Atheros driver (6.0.3.94)

Another nag we have found is another prompt describing that we are trying to connect to a server that is not selected as the default server for the profile. But a PAC was found in the system. Would you like to connect and make that the default server?.
Sorry for the translation. The message is in Spanish.

On top of that if you ignore the acceptance of the PAC before login and then log-on, the explorer process hangs as the acceptance window is hidden until you press Ctrl +Alt+Del

There is a similar behaviour fixed in a driver update for Intel PRO 2200bg, 2915abg, 3945bg, 3945abg, 4965ag, and 4965agn Mini PCI adapter

Has anybody seen this behaviour (bug)? Is there a solution to it?.
How can we examine the PACs and change the default server? Or is it just a matter of waiting for a new driver upgrade?
Thank you everyone for such a useful forum.
