Hi,
Not sure if this is the right mail-list but I was referred to this
mail-list to seek help.
I already asked for help in #linuxwireles chat room and Ubuntu Forums and
didn't get any help.
I copy pasted the question from forum post below, I would like to refer to
URL of the forum post but list-serv does not accept URL in email. (How can
I include link to forum post?)
The forum post contains all necessary information (system info, logs, etc.).

I need desperate help regarding my wireless connection problem. I cannot
connect to my university's wireless network which uses WEP802.1X security.
When I switch to Windows Vista, I can connect to university wireless
network.
But when I use Ubuntu, I cannot connect.
Also, when I use Ubuntu, I can connect to other wireless networks either
non-password-protected or WEP password protected networks. But I cannot
connect to enterprise networks.
The problem seems not related to Ubuntu per se, but one of the network
related packages (ie. wpa_supplicant, dhclient, etc).
I need help from an expert. I hope the right person reads this post and
helps me.
If you want me to perform debugging tests or tasks please let me know.

Thanks,
alper

Never found any problems adding an URL. Just make sure that you don't
use HTML.

Hi Alper,
please don't mail me privately. I only give public support so that the
whole Linux community can benefit.

Ok, so this is a regression in Ubuntu. That's good to know.

It's very difficult to install older components to a newer distribution.
Don't do that unless you know what you are doing.

It depends where the problem is, we still don't know that. Did you try
what I suggested in my previous email? That would help to pinpoint
what's broken.
wpasupplicant mailing list is [email protected], but I have no idea
about dhclient. I recommend filing a bug to Ubuntu as this clearly is a
regression and trying to investigate more where the problem is.

(Alper confirmed privately that the URL is correct.)
>From the logs it seems that wifi authentication was succesful:

>From this I can't yet conclude where the problem is. It might a problem

(driver/wpasupplicant).
Few things I recommend to try:
o manual IPs (for example, use same settings as windows gets from the dhcp
server)
o disable network-manager and run wpasupplicant manually
o try different dhcp client, like udhcpc
