This is a good deal b/c it comes with the 4 port switch unit. Basically you
plug the single ethernet jack unit into your router, and then take the 4
port one to your htpc/gaming console/streaming blu-ray player/roku type
device. These powerline networking devices handle streaming hdtv over the
air tv channels and 1080p blu-ray files a lot better than wifi N devices
because they are more consistent so you don't get that damn studdering all
the time etc
