No wifi after updated NetworkManager (Fedora14/KDE)


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.

Have exact same issue after updating yesterday (3/6). Fedora 14 w/ Network controller: Intel Corporation WiFi Link 5100. I was searching the web to find the answer with no luck.

Also, wifi works fine in Gnome desktop.

I tried using 'yum history undo' to see if I could undo the change. It looks like the update also installed kde-plasma-networkmanagement-libs and removed knetworkmanager-libs ... I tried to undo this, but it fails. Is there anything else I can try?

I also got another update to NetworkManager today, but this didn't seem to fix anything

Running `NetworkManager --no-daemon` and watching the output, it looks like the plasma widget isn't actually passing the key back to NetworkManager. I'm not too familiar with it, though, so I could be wrong.

I have the same problem, but without the wifi working I can't downgrade NetworkManager and NetworkManager-glib (no internet connection).

PS.
I got a cable to connect the router, downgraded both packages and the wifi worked again.
I use Fedora-14 64bits in my notebook.
Fedora-14 used to be very stable and reliable, now I'll wait until the fix of NetworkManager to update again.
Thank you radragun for the usefull hint.

The downgrade doesn't seem to be working here And I don't have the diskspace to install gnome. Still, I'm able to connect with a wire, so its only an inconvenience when I'm at home.

Does anyone know which pproject is responsible for this bug, and where their bug tracker lies? I have no idea where to report it to; I really hope someone does, and it'll be fixed soon.

?? the fedora 14 project

if you DO not want or like these types of bugs .... then do not use the current version of fedora
or stay 1 version back fedora 13 is STILL supported JUST FOR THIS REASON !!!!!

fedora is and will allays be a testing R&D distro
bugs WILL pop up VERY often .That is life with fedora
EXCEPT it or use something else that is NOT "bloody cutting edge" / "the NEWEST of the NEW "

SOLUTION:

Right click on nm-applet -> open Network Management Settings -> Other -> Connection Secrets: Switch to "In secure storage (encrypted)"

Does this solution work for other people?

No luck here (and I wouldn't expect connection to depend on if/how the keys are stored), but I notice an update for NetworkManager, so I can only hope this might result in something working.

I've tried your solution, but it became working for me with the option "Do not store(always prompt)" and from the second restart. Rather "ugly" but it works, thanks

Well, I forgot to tell you I was using updates-testing version of kde-plasma-networkmanagement. Probably it's fixed there. See https://bugzilla.redhat.com/show_bug.cgi?id=682972.

# yum install kde-plasma-networkmanagement --disablerepo=* --enablerepo=updates-testing

This update should be released as stable update in few days/weeks.
