Configure the 

 area as needed to set an ASCII Passphrase and 128-bit key.

7.

Configure the 

 field as needed to allow TKIP and WPA2 client 

interoperation.

Select the 

 checkbox to enable or disable 

the broadcasting of encryption key changes to MUs. Only broadcast 
key changes when required by associated MUs to reduce the 
transmissions of sensitive key information. This option is disabled 
by default.

Specify a time period in seconds for broadcasting encryption key 
changes to MUs. Set key broadcasts to a shorter interval (at least 
30 seconds) for tighter security on the WLAN's wireless 
connections. Set key broadcasts to a longer interval to extend the 
key times for wireless connections. Default is 86,400 seconds.

To use an ASCII passphrase (and not a hexadecimal value), select 
the checkbox enter an alphanumeric string of 8 to 63 characters. 
The string allows character spaces. The 

AP-5131

 converts the 

string to a numeric value. This passphrase saves the administrator 
from entering the 256-bit key each time keys are generated.

To use a hexadecimal value (and not an ASCII passphrase), select 
the checkbox and enter 16 hexadecimal characters into each of the 
four fields displayed.

WPA2-CCMP Mixed Mode enables WPA2-CCMP and WPA-TKIP 
clients to operate together on the network. Enabling this option 
allows backwards compatibility for clients that support WPA-TKIP 
but do not support WPA2-CCMP. Symbol recommends enabling this 
feature if WPA-TKIP supported MUs operate within a WLAN 
populated by WPA2-CCMP enabled clients.
