Wireless Security (Wireless Router only)
Wireless Security may be Disabled or Enabled with WEP or WPA (1,2) for protecting your wireless network.
The default mode of wireless security is Disabled.
It is strongly suggested that you Enable wireless security with at least WEP.
WPA will provide stronger security if your client devices can support it.
WPA-PSK (TKIP) / WPA-PSK (AES) Pre-Shared Key
Security Mode: Select WPA1-PSK or WPA2-PSK as required
WPA Algorithms: There are two types of WPA-Pre-Shared Key, WPA1 and WPA2.
WPA1 adapts the TKIP (Temporal Key Integrity Protocol) encrypted algorithm, which incorporates
Message Integrity Code (MIC) to provide protection against hackers.
WPA2 adapts CCMP (Cipher Block Chaining Message Authentication Code Protocol) of the AES
(Advanced Encryption Security) algorithms.
Note that older client devices may not support either or both WPA1 or WPA2 in which case you may need
to use basic WEP security.
It is recommended to use the highest level of security that your network devices can support.
WPA Shared Key: The key for network authentication. The input format is in character style and key size
should be in the range between 8 and 63 characters.
Group Key Renewal: The period of renewal time for changing the security key automatically between
wireless client and Access Point (AP). Default value is 3600 seconds.
Idle Timeout: The default idle timeout is 3600 seconds. The Timeout value is based on the case of no
data traffic is sent or received by a client device. If the Router detects no traffic in the wireless network, it
will start timing the clock and drop the session when it reaches the defined timeout value. A new session
will be re-established as required after the old session has timed out.
