Broadband network listed as LAN in adapter settings but internet still working

[manpreet66]

My laptop (single not in any LAN) is connected to a wired broadband connection but since I installed Win7 64 bit, my broadband connection does not appear in the 'adapter settings' or 'networking and sharing center' even though my internet is working fine. But my actual problem is that because of this, I am unable to share my internet connection with our older computer via Wifi. Our Older computer gets connected to my laptop using a usb wifi adapter but can not share internet. It is beacause I cannot right click on my Broadband connection and make it shared network because broadband connection is not listed in adapter settings instead it is listed as Local Area Network.
Here are some screenshots if they help :-

My only aim is to share my internet connection with other pc that runs xp.

How can I do this with above mentioned problem?

in Network and Sharing Center you should see a option to "Setup a new connection or network".

this should allow you to setup a wireless network for your XP computer to connect to
