[SOLVED] Wifi on WPA2 Enterprise not working anymore

[Klinux]

This is the situation:
PCLinuxOS 2010 up to date (still old kernel)

I can connect on wifi at my home (no encryptio)
I configured PClinuxOS to connect at my university (i entered all the data, login, username, WPA2 Enterprise, ...)
All works perfectly
This is with Kernel 2.6.33 ( I think)

In between I had update the kernel sometimes and all worked perfectly.

I update the kernel to 2.6.38 (latest in repository) and I was trying to connect as always, but
at home with no encryption it works perfectly
but at university (i can see the networks) when connecting it only says "Connection failed" with no other detailes.
So how to fix this?

you can go back to the kernel that works. There is really no point in updating the kernel if the one you have works with the hardware you have. There is a reason why the kernel is the only package that doesnt auto update on system update.

Before you connect to the network that doesnt connect, do the following.

1. Open the terminal and log in as root.
2. Run this command to make sure the system log service is running: "service syslog restart"
3. Try to connect to the wireless network
4. After the above fail, run this command on the terminal and give its output. "tail  -n  30 /var/log/syslog"

There is an updated wpa package in testing you might try or not.

Hi, I tried the wpa-gui and wpa_supplicant from the testing repository, still it does not work.
Is there a way I can connect through terminal so to have more error logs than only "Connection failed"?
Also if i delete the network, and then try to recreate one, I still see the old values (username, password), so this means it was not really deleted, how can i completely delete it?

go to "/etc/sysconfig/network-scripts/" folder and then delete a file named ifcfg-XXX where XXX is your interface name like wlan1, wlan0 etc. You have to be root to delete the file.

Thats the configuration file that contains the interface settings. It is usually not deleted when you delete an interface, its just overwritten with new entries when you recreate a new interface in pcc.

The first reply to your problem asked for most of the info needed to identify where the problem is. People ask for output of commands because they either have a clue of what a problem is or they want to rule out a possibility. To just ignore a post with request for information unnecessarily prolongs arrival of the solution if one can be arrived at.

Hi muungwana,
thanks for your replies, I was actually remembering the thing Textar said, so I didn't read the post (recently, I had read it, but forgot it, in the past).
I wrote down what u suggested me and was ready to try it out, i tried it and I got some output which I was ready to post here.
Still I wanted to be sure it was not a problem in my settings and be 100% sure it was an update problem.
I tried my backup (mylivecd) and runned live,...it worked, so I checked the settings and wrote some down.
I rebooted, and I was that one field was missing WPA-EAP IEEE8021X NONE was missing in the advanced section.
Now all works perfectly, so it was not an update problem, but a problem in the settings, thanks anyway.
Only strange thing is who did change that setting?
Marked as solved

I am glad you got it working, could you still post the output of those commands if you still have them?

It will be a lot easier next time to help somebody else if they fail to connect because they do not have that option set if an error pattern in a sysylog file can be identified with that option missing.
