This value should remain at its

default setting of

2346

If incon-

sistent data flow is a problem, only a minor modification should

be made.

Beacons are packets sent by the DI-774 to synchronize a wire-

less network.

Specify a value.

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.

Administrator

admin

(lower case) is the

default

name for the admin account. The admin

account has read/write access to the

router.

User

user

(lower case) is the

default

name

for the user account. The user ac-

count 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-774 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-774.

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 Server-

NTP is short for

Network Time Protocol.

NTP synchronizes com-

puter clock times in a network of computers.

This field is optional.
