My new Pi Zero W arrived on Saturday and is great except no wifi. Wired ethernet connection via a USB to Ethernet adaptor does work. Bluetooth I am not sure about: I can make it discoverable and connect to another device, but I haven’t managed to get the audio go to it instead of just to HDMI (where audio does work).
I have done the usual update and upgrade after following the recommended procedure for formatting an SD card and installing Raspberrian. I have reformatted the card and repeated the process in case something was amiss, but wifi has stayed completely inoperable throughout.
What would be steps to troubleshoot this problem?
