Super A Mode-

Super A is a group of performance enhancement features that

increase end user application throughput in an 802.11a network.

Super A is backwarsd compatible to standard 802.11a devices.

For top performance, all wirelss devices on the network should

be super A capable. Select either Disabled, Super A without Turbo,

Super A with Dynamic Turbo, or Super A with Static Turbo.

Disabled-

Standard 802.11a support, no enhanced capabilities.

Super A without

Turbo-

Capable of Packet Bursting, FastFrames, Compression, and no

Turbo mode.

Super A with

Dynamic Turbo-

Capable of Packet Bursting, FastFrames, Compression, and

Dynamic Turbo. This setting is backwards compatible with non-

Turbo (legacy) devices. Dynamic Turbo mode is only enabled

when all nodes on the wireless network is Super A with Dynamic

Turbo enabled.

Super A with

Static Turbo-

Capable of Packet Bursting, FastFrames, Compression, and

Static Turbo. This setting is not backwards compatible with non-

Turbo (legacy) devices. Static turbo mode is always on and is

only enabled when all nodes on the wireless network is Super A

with Static Turbo enabled.

CTS Mode-

CTS (Clear To Send) is a function used to minimize collisions

among wireless devices on a wireless local area network (LAN).

CTS will make sure the wireless network is clear before a wire-

less client attempts to send wireless data. Enabling CTS will

add overhead and may lower wireless throughput.

Auto-

CTS will monitor the wireless network and automati-

cally decide whether to implement CTS based on

the amount of traffic and collisions that occurs on

the wireless network.

Always-

CTS will always be used to make sure the wireless

LAN is clear before sending data.

None-

CTS is typically used in a pure 802.11g environment.

If CTS is set to “None” in a mixed mode environment

populated by 802.11b clients, wireless collisions may

occur frequently.

802.11g only mode-

Select this mode to restrict your network to only those devices

that employ the 802.11g standard. Enabling this mode will en-

sure that you maintain the highest connectivity rate, unhampered

by any connection to an 802.11b device.

Remote Management

Remote Management allows the DI-784 to be configured from the Internet by a web

browser. A username and password is still required to access the Web-Management

interface. In general, only a member of your network can browse the built-in web pages

to perform “Administrator” tasks. This feature enables you to perform “Administrator”

tasks from the remote (Internet) host.

IP Address:

Internet IP Address of the computer that has access to the Router. It is not

recommended that you set the IP Address to * (star), because this allows any Internet

IP Address to access the Router, which could result in a loss of security for your network.

If you elect to enable

Remote Management

, make sure to enter the IP Address of the

remote computer allowed to configure the DI-784.

Port:

For security purposes, select a separate port number used to access the Router.

(

The following is an example only; you may use a different port number.)

Example:

http://x.x.x.x:8080

where x.x.x.x is the WAN IP Address of the

Router and

8080 is the port used for the Web-Management interface.
