“I bought the zero W to run Pi-hole continuously having first set it up on a Pi 4. As this was intended to run headless, I set up my Wifi credentials in the boot up file on the microSD card only to find that Wifi would not work. After a week and several re-installs, I finally realised that the indented script in the wpa_supplicant file was not being recognised. Once I removed the tabbed entries it worked perfectly. It now runs continuously, powered from my router USB port providing me with add free browsing. Success!”
