Our wiring is subpar. Performance is noticably worse on powerline than ethernet. With a wired connection, I could stream some HD video to my PS3. With powerline, I get stuttering on some SD video (though not all thankfully). I think the speed tests put powerline about halfway between wired and wireless on my setup, but it's been a while since I tested.
