I have been trying to connect my M5STACK to my wifi and not having any luck.

I have also tried flashing to Firmware and I can get as far as scanning the QR code on my phone and switching the wifi network on the phone to M5Stack-7e2e. connecting on to it's 192.168.4.1. Scan networks. I find one put in its SSID and password and M5STACK restarts and then fails to connect. I have tried 5 different wifi networks.
Any ideas?
