3g data card route to wi - fi

You may turn your Windows7 PC into a WiFi hotspot. After this, you may connect to internet on other laptops, smart phones, etc using this WiFi connection. Check a simple video here:

In the 3G wireless adapter's Properties, enable Internet Connection Sharing on the Sharing tab, and choose the Wireless Network Connection from the picklist of all other network adapters (if the WiFi adapter is the only other network adapter, there won't be a picklist).
e.g.
Then in Network and Sharing Center, click Manage wireless networks. In that dialog click Add, choose Create an ad hoc network, read the notice and click Next.
Give it a Network name... that will be the SSID the other laptop will connect to.
Say, 3G-Share
I recommend the default WPA2-Personal Security.
For an easy-to-remember key you can use your phone number (at least 8 digits).
Check the Save this network box and click Next.
At this point, the ICS setup will change the TCP/IP v4 protocol to use the IP address 192.168.137.1, and the ICS DHCP server will hand out addresses in that range.

So have the other laptop connect to the adhoc network (3G-Share was the example I gave, but whatever you made it), and they should be able to get to the internet through your 3G adapter now.

ok
