A regression for WPA2 - 18:20
So for a while I was wondering why I could not use the ANU's WPA2 secure network from my laptop. I had heard reports that some Ubuntu hardy machines had worked. I run Debian unstable and a kernel.org 2.6.29.3 on this laptop.

I thought maybe there was some problem with my laptop hardware and maybe the iwl4965 chipset simply would not do it under Linux. However searching online suggested I should be able to make it do WPA2.

Thinking maybe the Ubuntu people had done it right and Debian was missing something I tried booting a Jaunty live cd. I also discovered the rather neat feature of suspend to disk (hibernate) in that you can hibernate your computer, boot off a live cd, use it, reboot and have your existing session come right back up normally on the next boot.

Anyway I booted up Jaunty and tried to authenticate, still failed in a similar manner to my Debian installation. Out of curiosity as I had heard of hardy working I booted my laptop on a hardy live cd. So network manager and iwlagn driver combined on either Debian sid or Ubuntu jaunty had failed to authenticate. Ubuntu hardy on the other hand, using an older version of network manager and the iwl4965 driver in the kernel worked fine. WPA2 authentication and use on the ANU Secure wireless network.

So now I need to find out where the regression has happened that means WPA2 is broken in more recent releases of the software (kernel drivers, wpa supplicant, network manager) on either Debian or Ubuntu.
