There are a few ways to get wireless working on your RPi, but as far as I can work out, this is the easiest. This tutorial is prepared for Raspbian distro, but will also work on most Linux distributions. The tool works in desktop environment as well as on a headless machine.
What I'm going to show is how to install wicd, a wireless daemon that runs on your system and provides easy wireless configuration.
Get your RPi machine to a terminal
Open a terminal window on your Raspbian, or access the machine with console cable (it is not recommended to install **wicd **using ssh, as you may loose connection at some point).
Get the packages
If you can get a temporary wired internet connection to the machine, you can grab the packages from the repositories. This is the easiest way to install wicd and the following line will install all the required packages in one go.
$ sudo apt-get update $ sudo apt-get install wicd-cli wicd-curses
Note: when prompted if you want to add any users to the netdev group, add your local user account (this is the one you specified during installation).
$ sudo adduser yourusername netdev $ sudo service dbus reload
If you got any errors saying that wicd couldn't start then you've probably got network-manager installed. Otherwise, skip this section.
Start the wicd daemon:
$ sudo service wicd start
We can stop any existing network managers ready to start wicd. You should only need to do this if you've been playing about with the wireless before. Turn off network-manager (if you have installed one) and restart your network:
$ sudo service networking restart && sudo service network-manager stop
Next, disable network-manager from boot start:
$ sudo apt-get install rcconf $ sudo rcconf
Uncheck network-manager and exit.
wicd-curses and configure your wireless network (if that's what you need) to make sure that everything is in working order and you can live without network-manager.
$ sudo service wicd start $ wicd-curses start
If you get any errors with wicd starting, try stopping it first and then starting again:
$ sudo service wicd stop $ sudo service wicd start
Add your account (the one you use to access your RPi) to users group:
$ sudo gpasswd -a USERNAME users
Nearly there now.
Finally, to configure your wireless, type the following line. If you're running the install script, this will be run for you:
From here on it's pretty simple. You should get a basic interface with a list of networks your wireless adapter can 'see'.
To enable wireless interface
wlan0, you can either
sudo nano /etc/wicd/manager-settings.conf and set
wireless_interface = wlan0, or from within the wicd menu hit p key and set it there.
- Highlight the one you want to connect to and press the right cursor key to configure it
- Scroll down and check 'Automatically connect to this network'
- Scroll down to the botton and enter the wireless key
- Press [F10] to save. You should be back at the list of networks with your network highlighted
- Press [shift] + c (capital C) to connect to the network
- Once connected (check status in the bottom left), press q to quit
When you're happy your wireless is working (try pinging https://www.google.com or your router) reboot the machine:
Congratulations, you now have wireless networking!
