Airfoil /Airplay on HomeHub 3
I've used Airfoil for ages to stream Spotify to my hi fi via Apple TV. However, until today I've had a TP Link wi fi access point replacing the wi fi duties of my HomeHub3. Today I had a fiddle and got it to extend my HH3 instead, so I'm effectively now connecting over wi fi to my HH.
Now my Apple TV no longer shows up in Airfoil and iTunes. Plug an ethernet cable in and it's there. So what's stopping it over wi fi using the HomeHub? I assumed it was a port forwarding issue but there's nothing online alluding to it.
