I am a big fan of powerline networking. I have a powerline network in my house to connect to my game console upstairs since my WiFi network gets sketchy up there. I don’t really like that the outlets in the game room are scarce and the adapter blocks one of my plugs though.
What I need is the new Trendnet TPL-307E adapter. It works like any other adapter and has a compact body. The big difference is that it has an outlet on the front so even when using powerline networking you can still use the outlet for other stuff.
The adapter supports one button set up of secure networks. It uses AES encryption to secure the network as well. You can get a single adapter for $69 and a kit of two is $129.99. Two of the adapters are needed to set up the network.
