Easy wireless config

Assuming your wifi card is recognised this tool will make your life a lot easier connecting WiFi from the terminal

sudo apt-get install wicd-curses

Easy as Pi – but it will however be required every time you boot into the RPi. Quickest booting-with-wifi-approach is installing some tools:

apt-get install wpasupplicant wireless-tools

put something like this (red part is wireless config) into the /etc/networking/interfaces

auto lo

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet dhcp
pre-up wpa_supplicant -Dwext -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -B -P /var/run/wpa_supplicant.wlan0.pid
post-down killall -q wpa_supplicant

generate a psk key for wpa_supplicant.conf file:

sudo wpa_passphrase YOURSSID YOURPASSWORD

you don’t want to have to write this key to a piece of paper when you don’t have internet access so to add the output tho the wpa_supplicant.conf file you do this:

sudo wpa_passphrase YOURSSID YOURPASSWD | sudo tee -a /etc/wpa_supplicant/wpa_supplicant.conf

and after that check the .conf file to see if all is there.

reboot and hope you’re ok!
