Summary: I'm going to qualify my judgement on the basic functionality of this product since I only just got it up and running but, like other reviewers, I have serious reservations about D-Links tech support and the competence of the people who write their manuals. The wireless signal in the back room of my home was virtually nonexistent after AT&T decided to grace me with a new router during a service call.
Summary: This product works very well. But there are a few VERY important restrictions. You MUST make sure the adapters are located on the same electrical circuit panel. I found these adapaters to work okay in my installation, but ultimately I returned them and purchased additional long range and super long range network extenders, access points, and bridges.
