This could probably be the ULTIMATE solution! Post a comment if it has helped you! With each new Windows version, Microsoft has unfortunately chosen to make life harder for people who use ad-hoc networks to connect computers together without the use of a middleman (the router). In Windows Vista, one could choose to save the ad-hoc network one is connecting to. But with Windows 7, not only is there no way of connecting automatically (well actually there is a shortcut for that, as below), but now one cannot save an ad-hoc network that one is connecting to. (One can only save an ad-hoc network one is creating in the host computer.) The biggest annoyance is that every time one connects to an ad-hoc network as a guest, one has to enter the password (network key) again. All of these problems can be solved with the steps below.
