So I have a raspberry pi 2. With a tp-link tl-wn823n dongle.
I have done everything correct. changed the ssid and password in the txt file.
I have reinstalled octopi. When I do sudo lsusb. It shows the tp-link tl-wn823n in the usb devices. But when I do Ifconfig it doesn't show the wlan0. and the dongles led light doesn't blink whatsoever.
this is my octopi-wpa-supplicant.txt file
