I've used MT before - but a long time ago.

I've installed a trial (24h) onto a mini-PC. It runs fine but the wireless card won't detect anything on scanning, and when setup as AP bridge displays 'disabled' (rather than running AP). I am sure I am missing something obvious but can't think what it is.
Card is WLE200NX - AR9280 - and is detected ok by RouterOS. (card is WiFi N)
I'm using the latest 7.13

Thanks!

Edit - I've tried a second, different card, which is also recognised (this time it is only 2.4 GHz) but I get the same problem - nothing detected. And yes, I've connected working, correct WiFi antennas...
