My dell laptop won't connect to my wireless Internet?

I got a dell laptop yesterday and I am trying to connect it to my wireless Internet so if someone can help me that would be great.

Once check whether the drivers are installed or not and you can go to device manager by right clicking on my computer, click manage and then check in the device manager whether is there ? marks are there or not.

If there the drivers or not installed, so I suggest you to download the drivers from the dell official website.

Make sure the router is turned on and once keep a open network so you will come to know whether the WiFi is working or not and after keep wps/wpa2 password to be secure so none other device can access.

If you have problem with the router you can hard reset the router, if not worked connect through LAN so you will come to know whether the problem of your laptop WiFi or LAN or the router's.

Once you have ever connected to Internet make sure you have good security software's like Avast, Norton and McAfee...etc because if you have a better security software you Laptop protected.
