Description Alexander Dutton 2009-04-08 15:45:15 EDT
After upgrading to NetworkManager- with yum I could no longer connect to my wireless network which was secured using WPA-PSK. The tray applet shows only one of the green dots when attempting to connect.

There is a caveat to this though. Currently my machine isn't booting graphically, requiring logging in in text-mode and then running 'startx'. I noticed that NM now uses PolicyKit so it's possible there's something missing as a result of this broken booting.

I notice that before when NM asks for a PSK passphrase to be re-entered it would display the old input. It no longer does this.

In the meantime I have downgraded to NetworkManager- and can now connect again.

If you're not running a GUI, how is the connection configured, through ifcfg files in /etc/sysconfig/network-scripts?

I'm not even that far. I upgraded to F11-Beta (NM 0.7.100-1.fc11) from Fedora 10 and after login, wireless networking seems impossible.

The widget is in my status tray with an X and 'Enable Networking' is indeed checked.

I went to system-config-network, providing root authentication then all of the interfaces (eth0, pan0, wlan0) are inactive (eth0 will work when plugged in). If I click on any of them, I am not offered the opportunity to 'Activate' the Wireless at all.

not sure that it's significant but...

modprobe -r acer_wmi

fixed it for me
Comment 4 Alexander Dutton 2009-04-16 07:39:23 EDT
Sorry about the delay. It turns out that as far as yum knew gdm wasn't installed due to a messed up switch from F10 to rawhide. Eventually the install that had been there broke. I've now reinstalled gdm (and various other things) and that doesn't seem to be relevant.

There seems to be very little rhyme or reason as to when it doesn't work. The chronology has been:

Working on Network A with old version
Upgrade to new version and no longer works with Network A
Downgrade to old and Network A works again
Try Network B and all is good
Upgrade again and it still works with Network B
Try Network A again and it doesn't work
Downgrade and it still doesn't work with Network A

iwlist provides the following about Network A:

This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

Is this still an issue with current F11 2.6.29-based kernels and latest NetworkManager-0.7.1-8.git20090708.fc11?  Also, what wifi hardware?  The output of 'lspci' should tell you for most cards.  Thanks!

etworkManager- has been pushed to the Fedora
11 testing repository.  If problems still persist, please make note of it in
this bug report.
 If you want to test the update, you can install it with 
 su -c 'yum --enablerepo=updates-testing update NetworkManager'.  You can provide feedback for this update
here: http://admin.fedoraproject.org/updates/F11/FEDORA-2009-10696  

a shot, and also make sure you're running the lasted kernel updates (  Let me know what the result there is.

If that still fails, can you including your /var/log/messages from the time the problem happened?  Thanks!
