Summary: I bought two kits to replace the wireless. The wireless provided a very weak signal to the second floor and was not fast enough for one user let alone multiple users. Placed one in the basement by the router and the other three in the second flour bedrooms. Works great. What is surprising is that the basement and second floor are on separate service panels and the signal was able to bridge the panels.
Summary: I plugged them in and they worked. I don't know if I get the 100mb top speed, but the speed is good enough for my purposes. I even have the source adapter on a power strip (not recommended). They seem faster than the older XPS 03? adapters I had been using.
