Hi, after any advice - however suspect there is a hardware issue with the pi.
Brief summary - had the pi initially working fine connecting to home wifi after setting wpa_supplicant.conf in boot volume prior to starting. This had been fine for a couple of weeks. Then after a restart it failed to connect to the wifi.
After much troubleshooting trying to reconfigure a new wpa_supplicant.conf I ended up re-imaging the SD card.
I have subsequently re-imaged the SD card multiple times now. Always with the latest raspberrypi OS.
In troubleshooting things I have tried include:
- creating new wpa_supplicant.conf file on the SD card and restarting
- in a clean OS and connecting via SSH over USB - the raspi-config utility fails when setting wifi config with “no wifi interfaces found”
- I have copied /etc/network/interfaces and /etc/wpa_supplicant/wpa_supplicant.conf to match another working raspberrypi and to match various internet posts. This either has no effect or upon reboot stops my ability to ssh over USB onto the device (and it doesn’t assign an IP address).
Appreciate if anyone has some suggestions.
