Setting up your Pi to connect to wireless AP’s can be a pain at times. wicd-curses is a nice command line program to get this going for you easily. Only issue i have found so far is it doesn’t seem to like accessing the network on both eth0 and wlan0 at the same time. Meaning if your eth0 is on a different subnet than the AP you are connecting to, you will immediately lose connection to your putty session when you tell it to connect to the AP. Other than that, really cool.
#Update and Upgrade your Pi first
- sudo apt-get update
- sudo apt-get upgrade -y
- sudo apt-get install -y wicd-curses
#you should see available wifi ssids. Options are listed at the bottom. If you just highlight and hit enter it should connect you right up. I recommend hitting P and adjusting preferences, like auto connect so it reconnects after a reboot.
