[SOLVED] How to change wifi on a PiZero setup (without ethernet adapter)

[Tim Curtis]

HDMI is not off but there is no TTY on PiOS Lite by default which means a shell login won't appear on an attached display.

If you access the root EXT4 partition on the boot media you might be able to modify the WiFi config manually but I've never done it that way and so couldn't offer any help.

Your best bet is to go with a new image but get that Ethernet adapter !!
