Wireless LED/Touchpad

Question

Is there a way to re-enable my wireless card after it has been disabled using a touch pad without rebooting? I have an HP laptop and the wireless card has this light/touch button which turns orange when the card is down and blue when it's up. Under the windows vista that the laptop came installed with, touching the LED toggles the wireless card on and off. Under arch, touching it when it's on toggles it off, and I can't figure out how to turn it back on without rebooting the system. The interface continues to show up in ifconfig, but anything I try to do with it has no effect. Touching the button again doesn't do anything.
If it's not possible to get the card back up without rebooting, would it be possible to disable the button so that I don't have to reboot the system every time it's touched?
Appreciate any help.

Answer 1

does this command work for you?
sudo /etc/rc.d/network restart
Or you could try this script:
#!/bin/bash
sudo netcfg2 -a # tell netcfg to take down every profile
sudo netcfg2 clean # tell netcfg to clear all its state info
for i in /sys/class/net/*; do
i="${i##*/}"
case "$i" in
lo|wmaster0) ;;
*) sudo ifconfig "$i" down;; # take down every hardware interface
esac
done
sudo modprobe -r iwl4965 # unload your wifi driver
sleep 5
sudo modprobe iwl4965 # reload wifi driver
Just replace the iwl4965 with the driver your actually using.  I don't use netcfg to configure my wireless as I use wicd but the script still works and will completely reset your wireless. Hops this helps!
