Dl-514 d'link can't read signal from macbook

I got this D'Link from work where it has been sitting for some time.Brought it home after purchasing a macbook. I've never set up wireless before and this is my first laptop. I don't have the start up disc but I did connect the macbook through ethernet to the Dl-514 and did the set up wizard at 192.168.0.1. The macbook just doesn't read the wireless signal. I've taken it to work where it reads wireless fine and it reads other signals from around the neighborhood, but I think this D'Link might be faulty. I've played with the network settings in the macbook and have also tried reseting the router. Any help?
