This weekend I got my hands on a couple of Corinex wall mounts and decided to test out how power-line Ethernet would pan out on my home.
My setup is particular in that I would want to use it to connect my attic with my main floor and I have X10 devices on the attic, so I was interested in checking out how power-line Ethernet and X10 would get along together on the same installation.
It turns out they get along famously, and even going through another phase into the attic I could still get 12Mbps out of the 14Mbps theoretical maximum for this equipment.
Apparently I can get my PVR in the attic and have the main server in the office do the file serving without having to worry about Wi-Fi connectivity.
