Issues finding network with D-link router

Hi, My girlfriend recently purchased a D-link wireless router. She is having issues as that she cannot see any signal from her laptop. There is a wired connection from the router to a PC, that works fine. But the wireless is not. I am in California at the moment (she is in Germany). I won't be there for another 2 weeks. She has a D-link DI524 router.

Anyways though, she has 0 knowledge on the subject, and I suspect she just set a password, and tried to plug and play. The result is, she cannot see any networks from her laptop. Presumably the router broadcasting, and her network card is on

Is there anythign specific I should be looking for here? (I know its a bit vague, but pelase bear with me here). I know it could be a million things. Also I am not familiar with D-link routers, have never used one. Any help would be appreciated. By the way, she is running win XP home on her laptop, its a dell inspiron laptop. Not sure what the PC is running, I presume XP as well. I would like to try and guide her over the phone if possible, otherwise she has to wait for 2 weeks until I am there to look at it.

Thanks
