My d-link dir615 keeps dropping my wireless connection

Hello,
My D-Link DIR-615 router keeps dropping the wireless signals. It will work if I am wired directly to it, but not with the wireless. Any help?

laptop or desktop?

if it is a desktop what kind of NIC?

how far are you away from the router?

how many walls and what material are the walls?
