This is an almost perfect solution for networking computers in a large (or really any size) house (or building). No need to run wires. No need for a complicated wireless setup with its vulnerabilities. If you are on the same electrical circuit - you are on the same network.Our set up is for sharing dsl internet access. The two computers are approximately 100 feet apart on different levels of the house with many walls in between. Having had limited success with wireless in similar situations in the past I was seeking another option and I have found it. Used in combination with a d-link broadband router, both computers access the internet with no noticeable speed difference.ONE DRAWBACK:The only issue we have discovered is a problem with some (not all) touch lamps on the same circuit. Our solution was to replace the lamp.
