I need to find a network security key on a computer. The Ethernet Broadband Router has already been setup and is also running through a wireless router. The key on the wireless router won't work. Where on the computer do I find the correct security key?

Hello and welcome to Tom's Hardware Forum.

Go Start then Run in XP - or use the Windows key plus R in Vista and Windows 7, then type in the following into the Open box, including all the spaces:-

cmd /k ipconfig /all

then press Enter and from the black form that shows up, take a note of the numeric code beside the Default Gateway icon - something like

Type exit to close the black form.

Open Internet Explorer and enter that code into the URL address bar as though it was a website. You're then at the login page to the router's settings utility and admin will usually be the login with either admin or password as the password but your router's instruction manual will help you there.

If you're in, seek out Wireless and then Security and take a note of the key. Sometimes it may be a passphrase, some a simple set of letters and others a hexadecimal code. You also may as well note which level of security it is - WEP, WPA or WPA/PSK 2 and then either AES or TKIP. Your computer will already know this but it's handy information to store. Note also that hexadecimal only contains numbers from zero to 9 and letters a to f so there's no confusion of I and O with 1 and 0.

Keep a note of that security key in My Documents and also outside the computer.
