Using Ubuntu Hardy Beta, Linux kernel 2.6.24, AMD64.
I have to connect to a campus (University of Verona, Italy; more information maybe available at https://wifi.univr.it sadly in Italian only, and I am not sure it is reachable from outside the university) WPA2 wireless network. It uses PEAP authentication, Dynamic WEP encryption, second phase: MSCHAPv2. It also requires user login, password, and a CA certificate (available at the web page I linked above).
At the same page a wpasupplicant configuration file is also available, so to allow people to connect from linux also.
In Ubuntu Gutsy 32 bit (Linux kernel 2.6.22.14 if I am not mistaken) I was able to connect through NetworkManager and precisely using the GNOME nm-applet.
However, since I switched to Linux 2.6.24, I have no more been able to connect, whether through NM-applet or from the command line, using wpasupplicant. The wireless functions perfectly, and there has been no change in its configuration, since I am using it now (Windows Vista, configured months ago). Reported also here on launchpad: https://bugs.launchpad.net/ubuntu/+bug/209602
Thank you for your attention.
Greetings

intel wireless just doesn't work on linux 2.6.24.4; wait for 2.6.25.x stable.

I hope, then, that Linux 2.6.25.x stable will be out sooner than 24th april (Hardy release date) otherwise I (and I guess also many other people) will be in a very bad spot until the kernel is updated...(I am not proficient enough so to compile a whole Linux kernel for my distro). Thank you very much for your attention, in any case.

Hello, Luca!

I'm replying to your message that didn't come to be through a mailing list. Please don't bcc: random people. It's a bad style.

2.6.25.1 will be out after the first bug is fixed in Linux 2.6.25. I cannot promise you that any such bug would exist. Actually, I hope that there will be no reason for 2.6.25.1 release.

In any case, putting pressure on wireless developers is not appreciated. Maybe you should learn how to compile Linux kernels. Or maybe you should talk to Ubuntu release engineers and ask them not to wait for 2.6.25.1 (provided that your implication is correct and they would wait).

Or perhaps Ubuntu could learn from Debian and do releases when the software is in a good state rather than at specific predetermined release dates. Or fix the bugs themselves and contribute them upstream.

Strangely I find with the 2.6.24 kernel currently in Debian, the intel wireless seemed to work great with WPA2 (at least on a 4965). Maybe that was 2.6.24.2 or 2.6.24.3 or something. It was a couple of weeks ago now. I haven't heard of the 4935 before.

Since nobody has mentioned that, it's possible to compile the latest wireless drivers for the current kernel (starting with 2.6.18) thanks to the compat-wireless package:

http://linuxwireless.org/en/users/Download

That should be of great help for those looking to use the latest wireless drivers without having to recompile the currently used kernel.
