I tried opkg update, and it did nothing. I have the wifi configured as i can go to it's web page via the browser. What am i missing ?
check /etc/opkg settings. You need to set a repository there.
You could for instance try the repo on iotdk/ (although built for Galileo).
If you want to try that repo you could run
cat > /etc/opkg/iot-devkit.conf <<EOF
src iot-devkit http://iotdk.intel.com/repos/1.1/iotdk/
EOF
and then "opkg update"
