My broadband connection is in the basement. My wife's computer is on the second floor.Now, I could either buy a wireless Wi-Fi router, or tear up a bunch of walls and install a couple hundred feet (or more) of network cables.The only question I had was, would this LynkSys router be powerful enough to travel up two storeys and through six walls.The answer, surpringly, was yes, it is plenty poweful.So not only are my wife and I sharing a fast internet connection, complete with firewall protection, but it took me only twenty minutes to get everything set up. And I'm no computer specialist.If you're looking for wireless connectivity for your second computer, your laptop, or your home network, I can't recommend this product highly enough.
