You don't tell what is the reason you need to reboot. If your wifi device driver crashes then possibly there is no other way (with that device) than rebooting. But if it is Network Manager getting confused then maybe try restart it: sudo service network-manager restart Or maybe install a newer linux kernel. But it really is shooting in the dark - please provide more info about what fails. - Jonas -- * Jonas Smedegaard - idealist & Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ [x] quote me freely [ ] ask before reusing [ ] keep private
