I bought a D-Link router and Laptop Adapter kit, I was wondering if I buy a Desktop Adapter does it have to be the same brand as the router as long as it is the same standard (802.11b/g)?
no it doesn't have to be the same brand
and the only one who recommends that it should be is the company that makes the router so you keep buying from them
How do you think people go around finding access points in the city if everything only works with the same brand ;P Or on campuses, or wherever else! Hehe, come on now, think
