I bought a Wifi USB key in order to connect my workstation to the wifi. It worked about week, and then, he tries to authenticate, but can't (I get prompted 3 times to enter the password (which is correct) but fails.

I'm on Fedora 17 x64, and my key is a NETGEAR WNA3100M

Here's more details :

I don't know what's going on, if it's the key that have a problem, or an update of the kernel, but now, I'm lost :/

Do you have any idea what's happening ? thanks! :)

Something similar happens to me too on Ubuntu with another WiFi USB key, everytime I upgrade the OS. Have you by chance installed any updates recently or changed the kernel?

Anyway, I am always able to fix it by recompiling the USB key drivers after every update.

I tend to have this issue every time after a kernel update as well. Same solution. –  nerdwaller Dec 12 '12 at 15:14
    
How do you recompile it ? –  Cyril N. Dec 12 '12 at 16:00
    
@CyrilN. have a look at the following guide, it's rather extensive but it may help you get a deeper understanding of the topic: ubuntuforums.org/showthread.php?t=885847 –  user1301428 Dec 12 '12 at 16:16
    
Thanks for the tip, I'll try to recompile my driver. –  Cyril N. Dec 12 '12 at 16:31
    
@CyrilN. ok, let me know if it works for you too –  user1301428 Dec 13 '12 at 13:15

I finally updated Fedora to the latest version (I was n-1 late) and the key started working again. I suppose there was some sort of bugs not fixed in the previous version that wasn't updated.

I checked the answer from @user1301428 because if you want to stay (for any particular reason) in a n-1 version of Fedora, you will probably have to do this method.

But if you can, I highly recommend you to update your version to the latest.

If the driver is the official Fedora one, driver recompiling and such shouldn't be needed at all. By the log shown, the driver seems to be working.

If you updated the kernel, Fedora should have kept the old one around. Try booting with the one that used to work, and check again. It that works, report the problem via bugzilla.
