First, a little background information. My father-in-law's house has a broadband connection through their cable provider. I have my own IP address with them for when I visit, so that I can get online using my laptop. Within 15 minutes, I had configured the Router so that it was now being treated by the ISP as though it was my laptop (it was connected), connected my laptop to the built-in switch via CAT5 and surfed the Internet through the router, and had then configured the wireless LAN and the wireless card in my laptop to talk with each other. Done. That fast. So no more cables running through my in-law's house as I move from one room to another with my laptop...I am untethered, and I love it!
By the way, I bought the device for eventual use in my own place, not specifically for use at the in-laws.
