wifi.sh

A very very minimalistic script to connect your Linux box to a WPA2 access point.

You must run this app as root!

Dependencies:

• iw
• dhcpcd
• probably, firmware-linux

Install dependencies on debian-based distros

$ sudo apt-get install iw dhcpcd
$ sudo apt-get install firmware-linux  # If your wireless card needs it.

Instalation

$ cd ~/code/third-party  # Or wherever you use to clone third parties repositories.
$ git clone git@github.com:cleberzavadniak/wifi.sh.git
$ cd ~/bin; ln -s ~/code/third-party/wifi.sh/wifi.sh .

Make sure your "$HOME/bin" is present in your PATH.

Or create a link directly into /usr/local/sbin. You decide.

Usage

$ ./wifi.sh -h  # Help!
$ ./wifi.sh wlan0 list | less  # List Access Points. Search for "SSID:"
$ ./wifi.sh wlan0 connect <ap-ssid>  # Connect into an WPA/WPA2 AP

Troubleshooting

"It is not working!"

1- This app only works with WPA/WPA2 access points.

2- You must have root privileges.

3- Your system can't have NetworkManager service running (service network-manager stop or whatever command your distro uses).

4- Read the source code (cat wifi.sh), understand what it does, research a little about wireless connections and solve your problem yourself.

5- If nothing else works, install NetworkManager or wicd. Both kind of sucks, but they use to work well enough for most cases.
