This might be the wrong thread to recommend it, but I've had good luck with TP-Link's Powerline Ethernet adapters. I switched to them from WiFi for my living room TV/Gaming/Streaming setup. I'm in a high interference wireless environment due to neighbor density (even in 5Ghz) and the TP-Link devices reliably push over 500mbps.
A downside of powerline ethernet devices is they use your house wiring as a hub-style network. While I think some support a form of MIMO, the more devices you have the worse performance will be. The TP-Links I have sport QoS, but I've not messed with it.
