Issue connecting lenovo ideapad to belkin router

Hello,
So my in laws have a belkin router to provide wireless access. It works great, you just find the guest access signal, connect, pullup your browser and enter their password to get online. I use it just fine with my kindle fire, my phone, and my desktop. We never could get it to connect to the wii but hey, it never bothered us. But today I brought over my brand new laptop and it isn't gaing access to the Internet. It connects with limited connectivity but the webpage to enter the password never comes up. My laptop connected at my house with no problems. Ive tried taking down my firewall but that didn't help. Any ideas?

Btw I'm not sure if it makes a difference but my desktop runs windows vista and my laptop is running windows 8.
