Windows 7 ships with the ability to turn any run of the mill wifi adapter into a working, basic wifi router.
Setting it up is a matter of running two commands……..
Step 1: Open a command prompt with administrator privileges. The usual right click, followed by “Run as Administrator” should do.
Step 2: Configure your network by typing in:
netsh wlan set hostednetwork mode=allow ssid=thisisagenericssid key=opensesame
Keep in mind that the key is your network’s pass-phrase. The rest should be self explanatory.
Right click on the adapter which has the internet connection and click on properties. Click on the sharing tab and enable Internet Connection Sharing
Step 4: Start your network with the following:
netsh wlan start hostednetwork
But The easier way makes use of a neat little application called Virtual Router.
