In KDE 4.6, my wifi doesn't come back on after my laptop wakes up from sleeping (whenever I close the lid). This script is, of course, useful any time you need to reset your wifi.
Copy this and save it as /usr/bin/resetwifi:
make it executeable (using 'chmod +x /usr/bin/resetwifi', and you'll then be able to run 'resetwifi' from the command line. This should be with root priveleges. Sometimes I have to run it twice to get my wifi back up.
Code: Select all
#!/bin/bash # script by brokenman killall dhcpcd killall wpa_supplicant rm -r /var/run/wpa_supplicant/wlan0* rm /etc/dhcpc/dhcpcd-wlan0.pid wpa_supplicant -c /etc/wpa_supplicant.conf -iwlan0 -Dwext & sleep 1 dhcpcd wlan0
If you are running in always fresh mode, you can copy this script to your rootcopy directory, i.e. /rootcopy/usr/bin and it will be inserted to /usr/bin at startup.
