Parameter

Description

Encryption Type

This device supports the following types.

 Open: In Open System authentication, the WLAN client need not provide its credentials to

the Access Point during authentication. Any client can authenticate with the Access Point and then attempt to associate. In effect, no authentication occurs. Subsequently WEP keys can be used for encrypting data frames. At this point, the client must have the correct keys.

 Shared: In a shared authentication, the WLAN client needs to provide its credentials to the

Access Point during authentication.

 802.1x: In 802.1x authentication, the device needs to negotiate with the radius server first,

then the device’s wireless clients need to use the radius username and password to finish

802.1x authentication.

Default Key

Once you select a certain key, such as key 1, wireless clients must use the same key, key 1, to connect to your device.

For WEB security mode, most smart phones only support key 1, so we recommend that you select key 1 of this device.

Parameter description of WPA-PSK, WPA2-PSK and mixed WPA/WPA2-PSK

It is designed for home and small office networks and doesn't require an authentication server. Each WLAN network device encrypts the network traffic using a 256 bit key. This key may be entered either as a string of 64 hexadecimal digits, or as a passphrase of 8 to 63 printable ASCII characters. If ASCII characters are used, the 256 bit key is calculated by applying the PBKDF2 key derivation function to the passphrase, using the SSID as the salt and 4096 iterations of HMAC-SHA1.

Parameters

Description

Cipher Type

Select WPA encryption type.

 AES: AES is short for Advanced Encryption Standard. This encryption algorithm ensures a

higher wireless rate.

 TKIP: TKIP is short for Timing Key Integrity Protocol. Wireless rate can only reach 54Mbps

with this algorithm.

 TKIP&AES: Compatible with TKIP and AES. The wireless client can use either AES or TKIP

algorithm to connect to the WiFi.

Key

Enter a security key that is either 8 - 63 ASCII characters or 8 - 64 Hex characters.

Key Update Interval

You can configure security key's update interval here within the range from 60 to 99999 seconds. If set to 0, the key will not be updated.

Parameter description of WPA and WPA2

WPA is opposed to WPA-PSK and is also referred to as WPA-802.1X mode. It is designed for enterprise networks and requires a RADIUS authentication server. This requires a more complicated setup, but provides additional security (e.g. protection against dictionary attacks on short passwords). Various kinds of the Extensible Authentication Protocol (EAP) are used for authentication. WPA-Enterprise mode is available with both WPA and WPA2.

Set up an interval for sending beacon frames. The range is 20~999ms.

Beacon frames are transmitted at a regular interval to allow mobile clients to join the network. Beacon frames are used for a client to identify nearby APs. In general, the smaller the value is, the quicker a wireless client can connect to the AP. the larger the value is, the higher the data transmission of the WLAN network’s efficiency is.

Fragment Threshold

Set up the maximum length of frames that can be transmitted without fragmentation. The range is 256~2346 bytes.

Fragmentation means to fragment a large frame into small pieces, with each piece transmitted and acknowledged separately. When the length of a frame exceeds the specified fragment threshold value, it is fragmented.

 A longer frame is less likely to be successfully received. Therefore, in a WLAN where

there is high error rate, you can decrease the fragment threshold to increase frame transmission reliability.

 In a WLAN network with no interference, we recommend that you increase the

Fragment Threshold to improve the data transmission throughput by decreasing the ACK times.

RTS Threshold

Set up the threshold length for RTS/CTS mechanism.

RTS/CTS frames occupy a certain network bandwidth so that only the frames larger than RTS/CTS threshold will enable RTS/CTS mechanism to avoid data sending collisions in a WLAN network. The RTS/CTS threshold range is 1~2347 bytes.

You need to set up a rational value: A small value causes RTS packets to be sent more often, thus consuming more of the available bandwidth. However, the more often RTS packets are sent, the quicker the system can recover from interference or collisions. We recommend that you set up a small value in a high-density WLAN network to decrease the probability of collision.

DTIM Interval

Set up the number of beacon intervals between Delivery Traffic Indication Message (DTIM) transmissions. The range is 1~255 Beacon interval.

The AP sends buffered broadcast/multicast frames with the configured DTIM interval. For example, if you set DTIM to 2, the AP will send buffered broadcast/multicast frames every two Beacon intervals.

Receive Signal

Define the minimum client signal level accepted by the device. If a wireless client’s
