Network Key (winXP) = Network Security Key (winVista, win7) = Wireless password.
What is a network key?
Everybody calls it something different, but a network key is the wireless password for your router. The wireless password is the one that allows users to connect to the router and access the internet. The wireless password should not be confused with the admin password which is used to access the router configuration page. However, on some Jetpacks the wireless and admin password is the same.
How do I get one?
If your router is a VZW jetpack then the default wireless password should be written on the back of the device on a white sticker. If that sticker has rubbed off or is not visible then there should be a backup sticker underneath the battery.
Post back and let us know your OS and the model number of your VZW device so we can provide specific steps.
