Laptop won't connect to home wifi

[Patriciachris]

We have a Toshiba laptop that connects to all wifi except the wifi in our house. We even purchased a new router with no luck. Our provider says all systems look fine. Our cell phones and pc connects fine. Only this laptop has a problem

Could you answer these questions so i can have an idea of what the problem is:

1) Does your laptop detect your home wifi?
2) Has it ever connected to the home wifi once?
3) What operating system (windows 7, 8, linux...) is it running?

Thanks
