Can not connect to specific router

[Juraj]

Hello,
I have NodeMCU V3 (ESP-8266 12E) and I can not connect only to specific router (when I create AP on my android phone with same password It works ok):
Router - ZTE Speedport Entry 2i

Hi,

Could your please provide the setting details of your router, and the UART output logs of ESP8266 connecting to the router for debugging?

Thanks for your interest in ESP8266 !
