None of my Raspberry Pi Zero 2W devices can connect to any password-protected WiFi network at home. Here’s what I’ve ruled out so far:
It’s not a hardware or OS issue—I’ve tested multiple RPi Zero 2W units and reflashed the OS.
The same SD card works fine when used in a Raspberry Pi 4B.
I’ve tried connecting to different WiFi networks, including my phone’s hotspot.
Strangely, the Pi Zero 2W won’t connect to my phone’s hotspot when I’m at home, but it works when I’m elsewhere.
This suggests something at home is blocking the Pi Zero 2W from connecting to WiFi. Possible causes:
My WiFi 7 router may be incompatible or causing issues.
I live close to a 5G tower, which could be interfering.
The error message on the Pi says: “No password or secret key provided.”
