I've got a new laptop with a wireless card which runs Windows 7. At work, I put the laptop in a docking station that gives the laptop a hardwired internet connection and functions pretty much like desktop PC. But there isn't any WiFi signal in my building that I can use, so various portable devices that depend on WiFi for an internet connection (iPod Touch and Kindle) are hobbled. I'd like to provide them internet connections without spending more money, if possible.
So what I'd like to do is install some sort of virtual WiFi router on my PC. Is that possible?
N. B. There is a related (but not identical question) that has an answer that I think will work for me. It won't hurt my feelings if this question is closed with a link to the other question, but I think they require different answers.
