I need to locate my WPA security passphrase
I 'lost' the connection between my HP printer (J6480) and in trying to reestablish it I get this message: 'Your wireless router requires a WPA security passphrase. The passphrase configured on your HP printer does not match exactly. Run the wireless network setup to re-enter your wireless network WPA secuity passphrase,'
I have no record of the passphrase. Can anyone help me locate it?
