modifications of this value are recommended.



DTIM Interval. The default value is 1. This value, between 1 and 65,535 milliseconds, indicates the

interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field

informing clients of the next window for listening to broadcast and multicast messages. When the

Router has buffered broadcast or multicast messages for associated clients, it sends the next DTIM

with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast and

multicast messages.

 Preamble Type. The preamble defines the length of the CRC block for communication between the

Router and a wireless network adapter. (High network traffic areas should use the short preamble type.)

In most cases, keep default setting as Long Preamble.

 Wireless Distribution System. When configured to operate in the Wireless Distribution System (WDS)

Mode, the wireless router provides bridging functions between the LAN behind it and separate LANs

behind other wireless router operating in the WDS mode. The system will support up to eight such

Routers in a WDS configuration.

Note that the wireless router running in the WDS mode can also support wireless clients access

simultaneously.

 Authentication Type. The default is set to Both, which allows either Open System or Shared Key

authentication to be used. For Open System authentication, the sender and the recipient do not use a

WEP key for authentication. For Shared Key authentication, the sender and recipient use a WEP key

for authentication.

 Encryption. The default setting is Disable, which means no encryption will be applied. If WEP is

enabled, you can manually or automatically program the encryption keys. These values must be

identical on all wireless devices in your wireless network.

There are two levels of WEP encryption, 64-bit and 128-bit. Higher encryption level offers higher level

of security, but due to the complexity of the encryption, they may decrease network performance.
