ifconfig wlan0 down works for me on my laptop.
For those who use Kubuntu (KDE 4+) and dont wan't to type that command on each halt/reboot, here's what I've done : create 2 scripts which are executable by root. One for halt, on for reboot. basically the script are #!/bin/sh ifconfig wlan0 down halt and #!/bin/sh ifconfig wlan0 down reboot Then, in the "Lgin Manager" configuration, change the commands to run from /sbin/halt to yourhaltscript and /sbin/reboot to your rebootscript. This way you'll enjoy a normal user experience. (but I don't know wht will happen if you use networked filesystems and so on, guess it's safe but ain't sure). stF -- Jaunty - Wireless issue causes laptop shutdown to hang indefinitely https://bugs.launchpad.net/bugs/365733 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
