using a Dlink di-514 wireless router as a repeater

[AzuthZero]

Does anyone know if it's possible to use a dlink di-514 wireless router as a repeater? Basically, there's a wireless network outside my window that my college supplies, but where my computer is, I can't connect to it. I just happened to have this router, and was wondering if there was anyway I could use it as a repeater. If not, what would I need to buy?

Thanks
