WM Access Domain Services Configuration
6 If WPA v.1 is enabled, select one of the following encryption types from the Encryption drop-down
list:
Auto – The AP will advertise both TKIP and CCMP (Counter Mode with Cipher Block Chaining
●
Message Authentication Code Protocol) for WPAv1. CCMP is an IEEE 802.11i encryption protocol
that uses the encryption cipher AES (Advanced Encryption Standard). Auto is the default.
TKIP only – The AP will advertise TKIP as an available encryption protocol for WPAv1. It will
●
not advertise CCMP.
7 To enable WPA v2-type encryption, select WPA v.2.
8 To enable re-keying after a time interval, select Broadcast re-key interval.
If this checkbox is not selected, the Broadcast encryption key is never changed and the Wireless AP
will always use the same broadcast key for Broadcast/Multicast transmissions. This will reduce the
level of security for wireless communications.
9 In the Broadcast re-key interval box, type the time interval after which the broadcast encryption key
is changed automatically. The default is 3600.
10 In the Pre-Shared Key box, type the shared secret key to be used between the wireless device and
Wireless AP. The shared secret key is used to generate the 256-bit key.
11 In order to proofread your entry before saving the configuration, click Unmask to display the Pre-
Shared Key. To mask the key, click Mask.
12 To save your changes, click Save.
