Wireless device support and stability have come a long way in Linux since i started using Ubuntu a few years ago.
Now and again though, something can happen to make you lose your wireless connection. Many people solve this by restarting network manager or by simply restarting the computer.
With a small script file, you can restart your wireless driver when its on the fritz, quicly and easily.
First create a file:
gksudo gedit /usr/local/bin/name-of-file
Then add the script code:
modprobe -r your-wireless-device
Save and close your file and give permissions to run it:
sudo chmod +x /usr/local/bin/name-of-file
Finall, run the script by typing in the terminal:
Hope this helps some people, not only with keeping you wifi going strong, but also with how to implement simple scripts to make computing easier and funner.
