If you want to connect your Internet-enabled devices (TV, Blu-ray, media player, game console,....etc) to your Internet router, consider Trendnet's Powerline. You have to get the 500Mbps version. Wireless may not provide enough bandwidth you need. Plug a unit into an electrial outlet near your Internet router, run a short network cable to the router, plug another unit into an outlet near your Internet enabled devices, wire to a network switch, then run network cables to the devices. You will get maximum bandwidth from your Internet router. Totally worth it!
