Hi All,
Been running volumio for a few years, worked flawlessly for Tidal. Recently I signed up for Qobuz, and streaming HiRes files has been terrible - lots of stuttering.
I’m using a Pi3B, with an Allo digi one. I decided a sensible plan would be to try an external Wifi adapter, as the signal being received by the internal card can vary from 6mb/s to 70mb/s.
Anyway - USB dongle installed

However, it’s not showing up as device

Wlan0 is the internal card as evidenced by the MAC address.
So, for now - real simple question! How do I get the Edimax USB dongle to show up as a valid interface?
Done an apt-get update and I’m on the latest version of Volumio.
Thanks in advance for any help/hints or clues.
