Now I'm in hotel not train I fiddled with last nights #tildagon problems:
WiFi.scan only returns the access points it sees when it's connected to its configured network, not when it is out of range of its configured network. Change the config to my phone hotspot and it can see everything around me again.
USB works again now I physically wiped down, blew into, and pressed hard onto the board. So I guess something sad happening around the connector.
