has been

chosen. This screen displays

the wireless performance

features of the Access Point

portion of the DI-784.

Fragmentation-

This value should also remain at its default setting of

2346

. If you

experience a high packet error rate, you may slightly increase

your Fragmentation value within the range of 256-2346. Setting

the Fragmentation value too low may result in poor performance.

Open System -

The DI-784 will be visible to all devices on the network. This is

the default setting

Shared Key -

In this mode, in order to access the DI-784 on the network, the

device must be listed in the MAC Address Control List

Full

is the default selection. Select from the drop down menu for

your selection.

SSID Broadcast-

Choose

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.

Administrator

Login Name-

admin

(lower case) is the

default

login

name for the admin account. The admin

account has read/write access to the

router.

User

Login Name-

user

(lower case) is the

default

login name

for the user account. The user account has

read-only access to the router.

Admin Password-

The

default

setting is blank - no password.

To change the pass-

word, enter and confirm the new password.

User Password-

The

default

setting is blank - no password.

To change the pass-

word, enter and confirm the new password.

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.

Default

NTP is short for

Network Time Protocol.

NTP synchronizes com-

puter clock times in a network of computers.

This field is optional.
