[App_rpt-users] New setup - connecting to WiFi

I have just written a fresh image (ASL_1.01-20180228...) from allstarlink.org to a Raspberry Pi 3. It boots ok, and now I need to get it connected to WiFi. I am digging thru docs and how-to pages on allstarlink.org and so far, no luck. I’ve gone thru the first time setup in asl-menu, but I can’t figure out how to get a list of WiFi SSIDs to choose from, etc. I am not Linux-savvy but comfortable poking around as needed. How can I get connected to WiFi? Thanks
