Let the data flow
"The following things suck:
Watching video over wireless"
Ah, that'd be why Netflix and Amazon Prime have been such disasters.
The protocol you choose to connect your devices has nothing to do with the service provider. I have WD TV Live, Raspi2 Kodi, Sony Bluray all offering these services and all wired. When I change the WD TV Live (say) to wireless instead, it is less reliable and clunky to use. For example, rewinding generally isn't possible. And if any other family member is doing wireless stuff, get ready for disappointment.
Wireless is good but not if you have the choice of wired. Switches are 10 a penny these days. Let the data flow.
Okay the Raspi2 doesn't do Netflix at the mo.
