i am using wateen usb on my laptop. and i want to share the internet from my laptop to my desktop computer. how i can do this?

By setting up a ad hoc network or simply buy a router with USB support, search PTCL section many thread exist there

have look at this thread esp. 12th post.

You can also setup a network wizard for your desktop computer! or you can make your Computer as Host and use Laptop as Wi-Fi Connection
