Unable to connect to wi-fi

I am trying to connect my new ipad to my home hi-fi but I can not get it connected. I already tried all steps on your web site (connect to network, reset ipad, reset network settings, reset modem, etc.) and nothing. I can see the loading circle moving but nothing happens. I have waited for up to 30 minutes and the only thing I can see is the loading circle moving. I have other devices connected, two iphones, one macbook pro, one samsung/android, one asus/windows laptop and one HP/Windows desktop to the same home network.

I need help connecting my new ipad to my home network.

Regards,
