I'm trying Fedora17 on a new Dell vostro 3360 and I have some issues.

When using the wireless connection after a random time, i'm not able to ping anything.

Thanks in advance for any help / suggestion.

PS : Same issue with many combinations :

  • kernel-3.3.4-5.fc17.x8664 and kernel-3.4.3-1.fc17.x8664
  • multiple ssid / hotspots
  • gnome / kde

More details :

Using wicd instead of NetworkManager seems to solve the problem :

yum install wicd wicd-curses wicd-kde wicd-gtk

systemctl disable NetworkManager.service
systemctl disable NetworkManager-wait-online.service 
systemctl stop NetworkManager.service
systemctl stop NetworkManager-wait-online.service

systemctl enable wicd.service
systemctl start wicd.service

In case of selinux issues, you can try this :

restorecon -v '/etc/wicd/manager-settings.conf'
restorecon -v '/etc/wicd/wireless-settings.conf'
restorecon -v '/etc/wicd/wired-settings.conf'
grep wicd /var/log/audit/audit.log | audit2allow -M mypol
semodule -i mypol.pp

If everything works fine, you can remove the NetworkManager applet and add the Wicd applet.
