Introducing the wifi-connect snap, Alpha 1 release, beta channel (snap version 0.8), for testing and comments.
Wifi-connect lets you find wifi APs to connect your device to, and then to make the connection (using a web page accessed over a temporary wifi LAN), without ever needing Ethernet
For example, you might need to connect your device to wifi at a conference. Or you might have a digital signage device that you need to connect to wifi. Wifi-connect lets you do this without any physical wiring.
For info and setup, see: https://github.com/CanonicalLtd/UCWifiConnect/blob/master/README.md
