WPA if the client only supports WPA. With the "WPA2 Only" option, the router associates only
with clients that also support WPA2 security.
Cipher Type: The encryption algorithm used to secure the data communication. TKIP (Temporal
Key Integrity Protocol) provides per-packet key generation and is based on WEP. AES
(Advanced Encryption Standard) is a very secure block based encryption. With the "TKIP and
AES" option, the router negotiates the cipher type with the client, and uses AES when available.
Group Key Update Interval: The amount of time before the group key used for broadcast and
multicast data is changed.
WPA-PSK
This option uses Wi-Fi Protected Access with a Pre-Shared Key (PSK).
Pre-Shared Key: The key is entered as a pass-phrase of up to 63 alphanumeric characters in
ASCII (American Standard Code for Information Interchange) format at both ends of the
wireless connection. It cannot be shorter than eight characters, although for proper security it
needs to be of ample length and should not be a commonly known phrase. This phrase is used
to generate session keys that are unique for each wireless client.
Wireless MAC Filtering
Choose the type of MAC filtering needed.
Turn MAC Filtering Disable: When "Disable" is selected, MAC addresses are not used to
control network access.
Add MAC Filtering Rule
Use this section to add MAC addresses to the list below.
MAC Address
Enter the MAC address of a computer that you want to control with MAC filtering. Computers
that have obtained an IP address from the router's DHCP server will be in the DHCP Client List.
Select a device from the drop down menu.
The rule of thumb:
In mixed mode, multicast key has to be TKIP, but unicast key can be different per stations.
In WPA or WPA2 only mode, unicast and multicast key can be only AES for WPA2, and TKIP
for WPA. (AES means the unicast and multicast key are all AES. TKIP/AES means multicast
is TKIP. But unicast can be AES or TKIP, which depends on the peer.)
