I'm new to linux so please be patient (and verbose with answers). I'm using a Mac G4 with Fedora 8 and a Linksys WMP54G wireless card. When I use System|Administration|Network in Gnome to "Activate" wlan0, the computer completely locks up with no error message - requiring hard-boot.

iwconfig reports in pertinent part

Any help is much appreciated!

Could you try the latest Fedora kernel?


05-04-2008 22:58:10

I got the install that I have from http//fedoraproject.org/en/get-fedora about a week ago. I was of the impression that it was the latest version. I now see that there is a beta version of Fedora-9. I was hoping for a less drastic resolution to my problem. If no one has any other ideas, I'll give it a try.

Also... in case it matters, the in-built wired nic is active and functioning correctly. However, when I use the gui network manager to de-activate it, it does not get de-activated.

You don't need a beta for Fedora 9, you just need the latest kernel...
I don't have a link at this time, but Fedora provides kernel updates and you simply need the very latest version to get the latest rt2x00 version.

I did try with last kernel by fedora

root@XBTO-HT~ #-> uname -a
Linux XBTO-HT #1 SMP Sat Mar 29 095446 EDT 2008 i686 i686 i386 GNU/Linux

and not work.

If remove modules and load again i can see this trace

Thanks for your help so far. I did uname -a and got the same kernel version as above. I also did yum update kernel and it appeared that there were no updates. Is that the kernel update you were referring to?

Can someone tell me how to obtain the kind of trace in the previous reply post? I'm using a PPC so mine may be substantially different.

Any other ideas anyone? I really have no idea how to begin troubleshooting this.

Updated kernels can be found here
http//koji.fedoraproject.org/koji/buil ... ldID=44780


07-04-2008 14:10:54

Another option
http//koji.fedoraproject.org/koji/buil ... ldID=44648

My problem was solved by downloading and installing kernel- The other kernel update you suggested (the first one) could not be installed due to failed dependencies. It was much easier to install the .fc8 kernel than to update the failed dependencies of the .fc9 kernel.

Thanks so much for your help!

My initial problem is solved but now I'm having a different problem - wlan0 cannot get an ip address from the wireless router. I'll keep working on that and come back here if I have another question.

I am trying to get a new version of the fedora kernel rolled out which includes a working rt2x00 driver. If you could test it and vote for it that would be great, it's got a more recent version number than you mentioned.

Run the following command as root.

yum --enable-repo=updates-testing update kernel

Reboot, test and if everything still works vote for it on this page.

https//admin.fedoraproject.org/updates ... -2008-3260

Add your name, some nice comment like it works on ppc

Click the Works for me button, this gives it the vote.
