Limited Access to a Wifi Connection?

-I'm at a friends house and I tried to connect to his wifi and it seems that it searched it fine, but it has full bars but has a triangle with an exclamation point in it. It says "Unidentified Network" and under that "No Network Access"

When I open it it says his internet routers name and then Limited Access with full bars next to it.

I've connected to all kinds of different wifi connections fine, why am I having problems with this one and how can I fix it?



I have the correct security key and we already tried to unplug the router and plug it in again, It didn't do anything or change it.



I am using a Compaq Laptop.

Please help, I would like it as soon as I can use it.

Thanks.hahaha
