Connected to ESP8266 wifi repeater, but no internet access
Posted: Mon Aug 05, 2019 2:07 amHi,
I have loaded a NODEMCU V,1 with Arthur Kushnutdinov,s code (https://gitlab.com/forpdfsending/ESP826 ... fiRepeater), with Arduino IDE 1.8.9.
I can connect to the extended AP with good quality signal, but no internet conexion.
I am an absolut newbie and need some help to find out the trick.
Thank you.
