I made a configuration with this config : 2 WLAN, 2 SSID, Dongle + integrated wifi on Raspberry PI 3B+
Everything is working except, not everybody cannot connect to the wifi. Samsung Smartphone cannot connect to this and some Windows 10 too. What can be the problem. Any idea? This is my WPA_SUPPLICANT CONFIG:
The SSID work and it is visible. Nothing appear, is like a loop, the user click on the SSID WORK and the device said, connecting... after a while the connection process stop and again connecting. For Windows 10. It says, Unable to connect to this network.
