step process:

1) Unpacking and positioning the OfficeConnect Remote 612

ADSL Router

2) Running the Installation Procedure

3) Configuring the OfficeConnect Remote 612 ADSL Router

This guide describes how to install and configure the
OfficeConnect Remote 612 ADSL Router for shared Internet
access. To set up your OfficeConnect Remote 612 ADSL Router,
you must have the following:

• An Internet Service Provider (ISP) account.

• ADSL Service already installed at your location, with an

available ADSL wall jack.

• A computer (PC) with a CD-ROM drive, Ethernet connectivity

and TCP/IP software. (Note: TCP/IP is automatically included
with Windows 2000, ME, 98, 95, and NT.)

DHCP: (Dynamic Host
Configuration Protocol)
:
Dynamic IP addressing is the
type of addressing scheme
most often used by Internet
Service Providers (ISPs), and
is also the type that is preva-
lent in many existing
corporate networks.

The OfficeConnect Remote
612 ADSL Router, which can
act as a DHCP server, is opti-
mized for use with dynamic,
rather than static, IP address-
ing.  

For most users, it is most
likely that your computer or
computers are already set up
for dynamic IP addressing. By
default, the router assigns IP
addresses dynamically to
each attached computer.

Before you run the installation procedure, each computer must be
properly set up with TCP/IP and optimized for use with dynamic
IP addressing.

Checking for Dynamic or Static IP Addressing

• From the Start Menu, select Settings, and then Control Panel.

Windows 95, 98 or NT: 

Double-click the Network icon. From the Configuration tab of
the Network window, select TCP/IP for the Ethernet Network
Interface Card (NIC) that will be associated with your router.
For Windows NT: Click the Protocols tab on the Network win-
dow, and then select TCP/IP. Click Properties. Click the IP
Address tab on the TCP/IP Properties window.

Windows 2000: 

Double-click the Network and Dial-up Connections icon, then
double-click the Local Area Connection icon. Click Properties
on the Local Area Connection Status window and then select
Internet Protocol (TCP/IP) from the list of components shown
on the General tab of the Local Area Connection Properties win-
dow. Click the General tab on the Internet Protocol (TCP/IP)
Properties window.

• If Obtain an IP address automatically (Windows 95, 98, 2000) or

Obtain an IP address from a DHCP server (Windows NT) is
selected, your computer has a dynamic IP address.

• If Specify an IP address is selected, your computer has a static

IP address.

• Click Cancel to exit the window, and then click Cancel again on

the remaining windows until you get back to the Control Panel.

When positioning your OfficeConnect Remote 612 ADSL Router,
make sure of the following:

• Unit is out of direct sunlight and away from sources of heat.

• Cabling is away from power lines, fluorescent lighting fixtures,

and sources of electrical noise such as radios, transmitters, and
amplifiers.

• Water or moisture cannot enter the case of the unit.

• Air flow around the unit and through the vents in the side and

back of the case is not restricted. A minimum of 1 in. (2.54 cm)
clearance is recommended.

Wiring inside the house may be causing interference.

Make sure that any filter or splitter that you received from your
ISP is installed properly.

There is another DSL device plugged into the same phone line.

Only one DSL device can establish a DSL link at a time. Even if
the other device is powered off, it may cause interference.
Disconnect all other DSL devices. 

LCP Retransmission or PPPoE Timeout

Using the User Manager, make sure you have entered the proper
VCI/VPI values from your ISP. Otherwise, contact your ISP.

Authentication Failed

The Internet Connection username and password are incorrect.
Use the User Manager to check and correct these settings.

Problems

Why can’t I browse the Internet from my computer?

There are many possible reasons why this could happen. Follow
the steps below to try and identify what may be causing the
problem.

1) Check the LEDs on the front of the Router. The Power, LAN

and ADSL LEDs should be green (and may be flashing). When
all the LEDs indicate a good connection, try to browse the
Internet again. If you still cannot connect to the Internet, go to
#2 below.

2) Make sure the PC is communicating with the Router. Go to

your Start menu (see Fig. 12 on page 7) and select the
Diagnostics option. The Diagnostics program will give you
information that shows the status of your connection(s). When
the Diagnostics program brings up a browser window, go to #3
below. If you did not run the Installation CD on this PC, you
can run the Diagnostics program directly from the Installation
CD; simply click on Diagnostics on the first screen.

3) Make sure the Internet Connection is up. On the Diagnostics

screen, you will see an entry for Internet Connection. If the
Diagnostics screen shows that the Internet Connection is down,
refer to the Troubleshooting section on page 9 to determine
your next course of action. If the Diagnostics screen shows that
the Internet Connection is up, try to browse the Internet again.
If it still fails, contact your ISP.

Which cable is which?

The cable that looks like a normal telephone line is your ADSL
cable. The slightly thicker cable with larger connectors is your
LAN (Ethernet) cable.

How do I uninstall?

Go to your Start menu (see Fig. 12) and select the Uninstall
option. The program will remove all programs and software
installed when you ran the Install CD.

Where is the User’s Guide?

If you have run the Installation CD, the User’s Guide has been
installed on your PC and can be viewed by accessing your Start
Menu (see. Fig 12).

If you haven’t yet run the Installation program, you can review
the User’s Guide directly from the CD. Simply insert the Install
CD into the PC and select the User Guide option from the
launcher screen.
