Excerpt: I bought these devices and they work for about 10 month . I notice my network connection started to keep dropping and then it failed.I even put the 2 devices right next to each other. Nothing.I'm not buying this brand again.
Summary: There is just no substitute for hard wiring with CAT-5 cable. These devices work fine, if they are on the same circuit (i.e. in the same room), but in the real world, in a real house, in different rooms, not so much.
Summary: I'm going to first start out by saying that this product worked fantastically... for a month or so. Since then, I have repeated dropped connections. I originally purchased this product because my wireless router is on another floor in my house and this was a great alternative.
