Frequently Asked Questions

When entering the IP Address of the DI-784 (192.168.0.1), you are not connecting to

the Internet or have to be connected to the Internet. The device has the utility built-in

to a ROM chip in the device itself. Your computer must be on the same IP subnet to

connect to the web-based utility.

To resolve difficulties accessing a

web utility, please follow the steps below.

Step 1

Verify physical connectivity by checking for solid link lights on the device. If

you do not get a solid link light, try using a different cable or connect to a different

port on the device if possible. If the computer is turned off, the link light may not be

on.

The following connections require a Crossover Cable:

Computer to Computer

Computer to Uplink Port

Computer to Access Point

Computer to Print Server

Computer/XBOX/PS2 to DWL-810

Computer/XBOX/PS2 to DWL-900AP+

Uplink Port to Uplink Port (hub/switch)

Normal Port to Normal Port (hub/switch)

The following connections require a S

traight-through Cable:

Computer to Residential Gateway/Router

Computer to Normal Port (hub/switch)

Access Point to Normal Port (hub/switch)

Print Server to Normal Port (hub/switch)

Uplink Port to Normal Port (hub/switch)

Rule of Thumb:

”If there is a link light, the cable is right.”

What type of cable should I be using? (continued)

What´s the difference between a crossover cable and a straight-through

cable?

The wiring in crossover and straight-through cables are different. The two types

of cable have different purposes for different

LAN configurations. EIA/TIA 568A/568B

define the wiring standards and allow for

two different wiring color codes as

illustrated in the following diagram.

*The wires with colored backgrounds may

have white stripes and may be denoted

that way in diagrams found elsewhere.

How to tell straight-through cable from

a crossover cable:

The main way to tell the difference

between the two cable types is to compare

the wiring order on the ends of the cable. If

the wiring is the same on both sides, it is

straight-through cable. If one side has opposite wiring, it is a crossover cable.

All you need to remember to properly configure the cables is the pinout order of

the two cable ends and the following rules:

A straight-through cable has identical ends

A crossover cable has different ends

It makes no functional difference which standard you follow for straight-through

cable ends, as long as both ends are the same. You can start a crossover cable

with either standard as long as the other end is the other standard. It makes no

functional difference which end is which. The order in which you pin the cable is

important. Using a pattern other than what is specified in the above diagram

could cause connection problems.

When to use a crossover cable and when to use a straight-through cable:

Computer to Computer – Crossover

Computer to an normal port on a Hub/Switch – Straight-through

Computer to an uplink port on a Hub/Switch - Crossover

Hub/Switch uplink port to another Hub/Switch uplink port – Crossover

Hub/Switch uplink port to another Hub/Switch normal port - Straight-through

Step 3

Configure you internet settings.

Step 2

Disable any internet security software running on the computer. Software

firewalls like Zone Alarm, Black Ice, Sygate, Norton Personal Firewall, etc. might

block access to the configuration pages. Check the help files included with your

firewall software for more information on disabling or configuring it.
