On a fresh install of raspbian stretch lite, after configuring wifi with raspi-config, everything work like a charm...
But when i turn off wifi on router my raspberry pi freezing after 1 or 2 minutes (each time).
The only thing i can do is to turn off power supply and turn on on to resume.
I've tried on 3 SD card, still the same. I've check hash of downloaded img ( it's good). I've tried with 2 different official power supply, still the same.
Anybody for a solution ?
