Hello,
I use ESP32 and on one chip the program when I turn on wifi continually restarts without wifi works OK.
I've tried a stronger source for CPU, but erase Flash has not missed it?
What could it be. Also in your book I was looking for info but also samples with wifi also report this error?

Re: Continuous reboot on WiFi
Then your issue is something else and I'd suggest starting your own topic, preferably with more information than just the reset reason you get.

Ooops, sorry thought this was on the post I put on 
Can you delete all three?
