Query: Wow. It works and was easy. Go figure.

Can't go wrong with this sucker. It's rare that I find a product easy to use and install, especially a networking product, but this one worked right out of the box. Just plugged it into my router and 15 seconds later we were done. My signals far away, through walls and on another floor went from 20-30% to 60-70% after installation. Now my whole house is covered.Don't buy an access point or wifi range extender. Just get this antenna for less.
