If you have a secured network it will require a key. The key, also called a password, passphrase, network key, security key or encryption key, is configured on the wireless access point or router of the wireless network to which you are trying to connect. If you are trying to connect to your personal wireless network, you need the key that was originally set up on your wireless access point or router.
If you do not have the key, it can be found in the wireless access point or router set up screens. Refer to the operation guide supplied with the device or contact the manufacturer for information on how to obtain the key. If you are trying to connect to a public wireless access point or router, consult the operator of the wireless network.
In most cases, the password for your home Wi-Fi® connection is a combination of upper and lower case letters and numbers. We recommend that you clearly mark the upper case letters along with letters like S, which can look like a number 5, or a Q, which can look like a G when you write them down. Most of the time, when Wi-Fi connections fail it is due to the password being entered incorrectly because of these types of errors. So it is extremely important to enter the password correctly.
