I am sure lot of people have run into this but I was not able to find a relevant posting on this issue.
Here is the problem.

I have my modem hooked up to a dlink 1310 wireless router.

This is located on the first floor.

I have a desktop on the second floor and there is no ethernet hook up there and my desktop does not have a wireless card.

I do have a Belkin Wireless router which also supports AP mode / Bridging.
So, this is what i want to do.

I want to connect my desktop to the Belkin AP with the cable which then would connect to dlink wirelessly.

I am new to setting up this. Can you suggest me how I can achive this?
