After updated to Fedora 15, you notice that your network connection had been disabled or permanently gone. Then you try to activate it on your system setting’s network but with no luck. What should you do now? You can’t online via cable or wireless as well.
I tried to search Google and Fedora for fixes. It was a bug stated at https://bugzilla.redhat.com/show_bug.cgi?id=696278. And this is how to solve it, read more on the below:
Please follow step as stated (login terminal as root first):
1. cd /etc/sysconfig/network-scripts/
2. You will see ifcfg-Auto_* (such as ifcf-Auto_WIFI_jonboy, etc), backup and compress it into another folder.
$ mkdir backup
$ cp ifcfg-Auto_* backup/
$ tar -czvf backupnetwork.tar.gz ifcfg-Auto_*
3. After that type in:
$ fixfiles relabel; fixfiles onboot; mv /etc/sysconfig/network-scripts/ifcfg-Auto* backup/
4. Now you will see it will ask you to save as temporary, choose N. You will need to wait some time for it to finish. Then reboot your machine. (It will readjust your SELinux, just wait for it to finish and reboot)
Network connection will re-appear after all had been done and rebooted. Hooray~
Another tips which is for Network manager solution, its very easy: run ALT+F2 type “nm-connection-editor” and you will get the network settings editor, can add the mobile connections and manage all network connections.
