Some problems with wifi module on fedora (may be only with rtl8192se driver).
Here is the discription of the problem (link)
I have a laptop (Zoostorm Kangaroo VME50) running Fedora 14. I try to keep up-to-date, but usually only get around to running updates every week or 2.
I’m using rtl8192se wireless drivers, downloaded from a link someone posted on here. When I got the last kernel update, I just rebuilt the drivers rather than checking if there’s a new version.
Today I was trying to connect to a VPN, so did `yum install kde-plasma-networkmanagement-openvpn (assuming that normal dependency resolution would pull in all the other relvant packages … I’m not sure if that’s sane or not). Among the new packages, NetworkManager was ‘updated for dependencies’.
After a reboot, the VPN tab in NetworkManager appeared, but I was immediately prompted for my WEP key. (Not my house, not my network. The hex key is written down on a piece of card, so that’s quite a hassle)
After entering the key, the networkmanagement plasma widget kept on showing the status as “Waiting for authorization” … on reboot, or trying a different network, it does exactly the same.
When I plugged in the wired network cable, the KDE crash handler pops up with a segfault from NetworkManager. Unfortunately, the window vanished before I could take in any more than the fact that most of the stack trace visible was full of references to Qt* stuff.
The plasma widget still shows the icon for wireless, with the little ‘key’ that normally appears when its asking for a passphrase or key; the wireless network (“FAMILY”) disappeared from the list of available networks, but the interfaces list still shows “WLAN Interface: Waiting for authorization”. However, it appears the wired network is connected, so hopefully someone can tell me what’s the issue here, or at least help to track it down.
I don’t have a clue where to look.
The best way to solve this problem till now is to make downgrade
yum downgrade NetworkManager NetworkManager-glib
than restart Network manager service
