Basic Infos

The most basic setup provided by the example generates another SSID which i don't know where it comes from. I am able to connect, it gives away some IP on the 192.168.4.x subnet but, i cannot reach .1 of the subnet (ping works).
Data has been reset with wifiManager.resetSettings();, problem persists.

SSID Name is FaryLink_53D409 (only god knows where this name comes from, i searched everywhere).

WiFi.getmode() = 3, so it is WiFi_AP_STA
(which makes sense, but how can i change that?)
