Unicast messages are addressed to a single device on the network. Broadcast messages are

clients in that subnet.
Pre-Shared Key Enter either an alphanumeric string of 8 to 63 ASCII characters or 64 HEX characters as the primary
string both transmitting and receiving authenticators must share. The alphanumeric string allows
character spaces. The access point converts the string to a numeric value. This passphrase saves
the administrator from entering the 256-bit key each time keys are generated.
