Fixing Ubuntu Issues: Restart Wireless Without Reboot

Sometimes after resuming from sleep, you would find that your wireless connection no longer works. Up until now, my only solution to this was to reboot. I've found an alternative solution from user mariosx on http://ubuntuforums.org/archive/index.php/t-913407.html that involves simply restarting the wireless interface. To do so, enter the following in a terminal window


sudo ifconfig eth1 down
sudo ifconfig eth1 up

Where eth1 = your network interface. Could be wlan0 or something like that. I have not yet tried this out, but it's one of the more sane solutions i've come accross for this problem during my searches.
