I'm looking for about 4 of these, so the Shield is out of my price range.
I've got an aged nexus player (no network port, no ADB over WiFi) and I've been playing with an x96air but can't get Netflix to work on any ATV custom ROM (ATV version). It needs to be androidTV for ease of use for the family.
Can anyone suggest a cheap option for a wired androidTV box that has Netflix and ADB over network?
I think the Mi Box S or the Jetstream 4K are your only low cost options that have a network port and support Netflix HD. Not sure about wireless ADB support.
You could also consider a Fire TV Stick with LAN adapter. That would cover your requirements for LAN, wireless ADB support and Netflix HD capability.
