Try another USB Ethertnet adapter. That's the key piece for this hack. Ensure its a 2.0 USB unit with chipset AX88772
Good luck !

I am struggling to find any that says AX88772, I’m sure somewhere said the one I bought had it (mobi lock USB 2 Ethernet adaptor on uk amazon). Does anyone have a link to one in the uk that is confirmed as working with the latest firmware?
