MacBook won't connect to network

[Finagle77]

I have a MacBook pro. When I first brought it to my boyfriends house I got their network name and password. The MacBook remembered it and automatically connected to the network when I turned it on. But one day it just stopped. It won't give me an Internet connection. It still remembers the network and signs in but then I get that exclamation point over my connection status and I can't connect to the Internet. I've tried removing the network from the remembered list, restarting the computer, and re-entering the password, but it still won't connect.. Any advice/ideas? Please. Anything will help.

Is it just at your boyfriend's house that it won't connect?

Did you try rebooting the router? Rebooting the modem (cable, DSL, whatever?)

Yeah it's just my boyfriends house. I'll see about restarting the router. Thanks

Restarting the router didn't do it..

What kind of router is it? I remember having trouble with a older dlink router not connecting with my Macbook Pro. If you post the router with model number maybe someone can help you out
