After a lot of huffing and puffing and making things over-complicated, I got my Raspberry Pi on the internet by wifi with the miniscule £8.27 EdimaxEW-7811UN WiFi dongle. Here’s how I set it up. NB: I’m using a Kindle power supply, which seems to provide enough current to run this tiny wifi adaptor plugged straight into the Pi’s USB socket (which will be important for FridgeGizmo). I am also using Raspbian wheezy 2012-08-16 as my OS.
1) I updated my firmware by installing and running rpi-update: https://github.com/Hexxeh/rpi-update – new firmware includes drivers needed by this wifi dongle.
2) I followed these instructions: http://raspberrypi.stackexchange.com/questions/1244/wifi-on-raspberry-pi-raspbmc
specifically the bit where you go to the root terminal and type:
and add the below text to the end of the file:
iface wlan0 inet dhcp
Then in the terminal type:
and add the below text replacing NETWORK_SSID with my wifi network name and NETWORK_PASSWORD with my wifi password:
Then at the command line I typed
sudo ifup wlan0
and my wifi dongle lit up blue, and I got on t’internet. Phew!
