I just installed this product, read many of the mixed reviews. While I did not see an "increase" in signal strength in areas that were previously covered with my Linksys Wireless Router, I did see a huge difference in areas that were unable to connect or received a weak signal. I now have adequate coverage in all corners of my home! It was easy to install, tech support was quick to send me a TNC connector for my router, and I am now completely wireless!
