Windows 8 Laptop is unable to connect to network?

[VexaRepublic]

I just recently added a password to my wifi because neighbours were using it.Everything was working fine before.I have 2 laptops.The first one is Windows 7 and it connected perfectly fine.The windows 8 one is saying it's unable to connect to network.I went into properties and set the passwords correctly.Does anyone have this problem or know how to solve it?

.unplug everything, start the router first and wait a few minutes then start the laptop up and try to connect to your wifi. if nothing then use the troubleshooter in the control panel
