This is a very common question or problem that you will encounter if you have a wireless network. So I have decided to make a hub for this. This hub will give you the steps on how to check or get the network key of your Wireless router. The steps here can be applied to old or new versions of Netgear wireless routers, most likely they will have the same or should I say almost the same way on how to check or get the network key. This step is very easy, just follow the steps below. I copied this from the forum where I have posted it.

To answer the question "Where can I get my network key?" Your network key is set or saved on the router setup page. To get this, just open your browser (Internet Explorer or Firefox) on the computer that is wired directly to the router. Then type in the address bar http://192.168.1.1/or http://192.168.0.1/ the address will depend on the version of your router, or just try both, it will ask you for a username and password, by default the username is admin and password is password. Once you're on the setup page of your router click on the wireless settings on the left hand panel. Then look for the wireless security settings - if the security is set to WEP - Key1 will be the network key or which ever has a tick. Or if the security is set to WPA the passphrase is your network key. Now that you know the network you can now type it once you are prompted when try to connect to your network.

I hope this has been helpful and informative to all of you.

Thank you for reading and have a nice day!
