Summary: I bought this recently and here is my summary: -high end house built in 1994 -plug and play? Yes you bet! -Speed as advertised? NO, I plugged one in my office directly from a gigabit router in directly into the outlet. The other end is plugged in an outlet(kitchen) just 2 rooms away. Speeds are so and so, very often the LED is red which shows the slowest speed. 500M is prob advertised for 2 outlets next to each other?
