[SOLVED] Fresh install Pi-4 rev 1.5 not joining network

[rawdlite]

<snip>

On a different tack, I have now tried Moode r761, r750 & r671 images.  Same issue - no ehternet or AP connection.  I also tried current [whisper it!] Volumio... same issue!  There must be a clue in that for a clever person. 

Could you attach a monitor and keyboard to Rpi4?

Other things to try:

- Force AP-Mode by writing 'None' to SSID 
- Disable DHCP and manualy assign an IP Adress.

HTH
