This is a short guide to set up an Intel Galileo (or alternatively a Yún, or other small embedded systems who can run Linux) to connect to a wi-fi network, and particularly an eduroam network. Note that if you're using a Raspberry Pi I've found that it's significantly easier to use NetworkManager to do that, but this might not work on Yocto Linux.
(These notes were written in 2014 so they may be outdated by easier processes.)
FIRST you need to have your Galileo set up with the full Linux image (on a microSD card) and a working access to the terminal (via USB or UART). (If you're on OSX or Linux you're probably better off using screen
, worked better than CoolTerm which didn't support backspaces and vi). There's plenty of tutorials online to do this. All commands here have to be typed in the terminal of the Galileo.
