Retrieve Your Wireless Network Security Key in Windows 7

Have you experienced a situation where you have to add a computer to your wireless network and you can’t find the network security key? Windows 7, like previous versions of Windows, remembers (with your permission) the network security key when you first connect to a secured wireless (Wi-Fi) network protected by WEP, WPA, or WPA2. This allows Windows to automatically sign in to the Wi-Fi network when it starts up.

To use this procedure to recover your network security key, you must have a computer already connected to your Wi-Fi network. Windows 7, unlike previous versions of Windows, allows a fairly easy way to view your network security key on the screen in plain text.

NOTE: Because the network security key will be displayed in plain text, be very careful when and where you use this procedure. Make sure no one is around peering over your shoulder or glancing at your screen.

To begin, select Control Panel on the Start menu.

01_opening_control_panel

If you have selected Category as the Control Panel view, click Network and Internet.

02_clicking_network_and_internet

On the Network and Internet window, click Network and Sharing Center.

03_clicking_network_and_sharing_center

If you have selected Small icons (or Large icons) as the Control Panel view, all available items on the Control Panel are available. Click Network and Sharing Center.

04_network_and_sharing_center_small_icons

On the Network and Sharing Center, click the Manage wireless networks link in the left pane.

05_clicking_manage_wireless_networks

Your wireless networks are listed on the Manage wireless networks that use window. Right-click on the wireless network for which you want to view the network security key and select Properties from the popup menu.

The Wireless Network Properties dialog box displays for the chosen network. By default, the key in the Network security key edit box is displayed as dots rather than plain text. To view your network security key, select the Show characters check box so there is a check mark in the box.

NOTE: To protect the security of your network, as soon as you have your security key, select the Show characters check box again so there is no check mark in the box and your security key is displayed as dots again.

Click OK to close the dialog box.

07_clicking_show_characters_orig

Again, be very careful where you view your network security key in plain text to preserve the security of your network. Only use this procedure if you really need to.
