1 Enter the pre-shared key in the Pre-shared Key (PSK) field. The pre-shared
key is a password, in the form of a word, phrase or series of letters and
numbers. The key must be between 8 and 63 characters long and can
include spaces and symbols.
Note that each client that connects to the network must use the same
key.
2 Optionally, check the Hide PSK check box, if you want the key that you
enter to be shown on the screen as a series of asterisks (*).
3 Click Apply.
