Unable to use TP-link TL-WN823N with octopi

Hello, I cant seem to get my tp-link tl-wn823n to work with octopi, I have configured my network settings in the octopi-wpa-supplicant.txt but when i start up the pic I cannot find it on my network, it works fine with an old wifi dongle that i found and works ok with the Ethernet connection but cant seem to get the tp-link dongle to play ball...

I'm using OctoPi 0.15.1 that i downloaded and installed last night, and my printer is a Creality 3D CR-10 Mini

Any help that you can give me would be gratefully received :slight_smile:

Cheers,
Azean
