In my last post, i gave you a simple tutorial on adding a minimal install of Gnome, i forgot to mention that if your using a Raspberry Pi 2 on a wireless network rather than a wired network you won't be able to connect to your router as the system tray icon will say device not ready when using a wireless adapter.
The easy way to fix this is by installing Wicd and this is simply done by opening the terminal and using the following command:
Wicd: sudo apt-get install wicd
Follow the onscreen prompt to install and reboot, remember the command for reboot is:
Reboot: sudo reboot.
Once your all rebooted and logged back in you will notice a new tray icon, similar the windows network icon, if you enlarge the picture above you can see it. Right click on the icon and connect to your wireless network, alternatively you access wicd through it's GUI through the Applications - Internet menu.
