use your computer to access the router settings then wireless settings then security and it'll be in there somewhere

Usually you just paste the ip of the router into your web browser. I think netgears are usually 192.168.0.1 network:

http://192.168.0.1

If you don't know the ip you can try clicking start-->run-->then type cmd and click "OK". In the command prompt type: ipconfig and press "Enter" on the keyboard. If there's a "gateway address" that will the the number to type after http:// in your browser.

Ethernet adapter Wireless:
Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.1.105
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1

when performing the above I receive media state....media disconnected.
how is this resolved?
