Prepare the Router
Do the following to prepare your router:
•
•
•
Order ISDN service from the phone company.
Configure your PC to use the TCP/IP networking protocol.
Order Internet service from an Internet service provider (ISP).
The following section provides an overview of the requirements.
Ordering an ISDN Line
Contact the ISDN sales center of the phone company and order an ISDN Basic
Rate Interface (BRI) phone line. In North America, provide the phone company
with an ISDN ordering code (IOC). NETGEAR recommends codes IOC “U” or
EZ-ISDN1 for the Model RT338 router. Additional information about ordering
an ISDN line can be found in the Model RT338 ISDN Router Installation Guide.
When the ISDN line is installed, make sure you have the following information:
•
•
•
ISDN directory number(s)
Service profile identifier numbers (SPIDs) (North America only)
Switch type and protocol of the switch (such as National ISDN NI-1) used
at the telephone company (North America only)
Order any additional ISDN or phone service at this time.
Setting upYour Network
The Model RT338 router uses the Internet Protocol (IP). To access the Internet
using the Model RT338 router, all PCs must have TCP/IP installed and selected
as their networking protocol. TCP/IP is built into Windows® 95, Windows 98,
and Windows NT® but must be enabled and configured. Refer to “Configuring
TCP/IP Properties” for instructions to install IP networking.
In an IP network, all PCs must be assigned IP addresses. Most LANs use private
IP addresses. These addresses are assigned automatically by the Model RT338
router whenever a PC reboots. Refer to “Using Private IP Addresses” for
instructions to use private IP addressing.
Model RT338 ISDN Router Installation Guide
Download from Www.Somanuals.com. All Manuals Search And Download.
All PCs must also have other IP configuration information, including a subnet
mask, a domain name server (DNS) address, and a default gateway address. This
information is also assigned automatically by the Model RT338 router whenever
a PC reboots. For more information about these parameters, refer to the Model
RT338 ISDN Router Installation Guide.
Using Private IP Addresses
Using the DHCP protocol, the Model RT338 router assigns private IP addresses
to all the PCs on your LAN (when the PC reboots). The Internet Engineering
Task Force (IETF) reserves these addresses for use in private networks:
•
192.168.0.1—local IP address for the router (This address also serves as the
DNS address and default gateway address for all of the PCs.)
•
•
192.168.0.2 through 192.168.0.32—IP addresses of your PCs
255.255.255.0—subnet mask for your router and PC
Setting up an ISP
Contact an ISP and request a single-user Internet access account. You can
connect a multiuser LAN through a single-user account by using the Network
Address Translation (NAT) feature on the router.
In a single-user account, the ISP assigns one registered IP address to use. With
most accounts, this address is assigned dynamically each time you log in to the
account, so you will not need to know the actual address. The NAT feature
translates the private IP addresses of your network PC(s) to this address for
accessing the Internet.
Account Information
The ISP should give you the following information for your account:
•
•
•
Local phone number for accessing the ISP
Login name
Password
Questions to ask the ISP
In addition, you should ask your ISP these questions:
•
Will the IP address be dynamically assigned?
Refer to the Model RT338 ISDN Router Installation Guide on the Model
RT338 Resources CD for instructions to configure a static IP address.
•
•
Will your DNS server address be dynamically assigned?
If not, enter it in FirstGear’s ISP connection.
Does your ISP support Multilink Protocol?
If you want to connect both ISDN B channels simultaneously for a
128 Kbps connection, your ISP must support Multilink Protocol.

protocol. TCP/IP installation must be done manually.
To configure Windows 95 or Windows 98 for IP networking:
•
Select the network properties from the Windows Control Panel.
Find your Ethernet adapter, TCP/IP protocol, and Client for Microsoft
Networks. If these do not exist, you must add them.
To add an Ethernet adapter:
a. Click on Add.
b. Select Adapter.
c. Click on Add (again).
d. Select the manufacturer and model for the Ethernet adapter.

To add a Client for Microsoft Networks:
a. Click on Add.
b. Click on Client.
c. Click on Add (again).
d. Select Microsoft.
e. Select Client for Microsoft Networks.
f. Click on OK.
Restart your PC after making these changes.
Configuring TCP/IP Properties
NETGEAR recommends that you keep the default settings for the TCP/IP setup
parameters, because your PC is configured to obtain its TCP/IP configuration
information from a DHCP server on the LAN. The Model RT338 router is
shipped preconfigured as a DHCP server and assigns the TCP/IP configuration.
To obtain the configuration information from the router:
1. Turn on power to the router.
Wait at least one minute before continuing to step 2.
2. Reboot each PC on your LAN.

on the Model RT338 Resources CD and on the NETGEAR Web site at:
Verifying the Installation
When the router is configured correctly, it will place a call to the ISP
automatically whenever a configured PC tries to access the Internet. The router
disconnects from the ISP when the connection has been idle for a period of time.
Therefore, the Dial-Up Networking, login, and disconnect processes are
performed by the router.
To access the Internet, launch a browser application (that is, Microsoft® Internet
Explorer or Netscape Navigator). The B1 LED on the router illuminates,
indicating that a call is being placed. Next, the LAN activity LEDs (TD and RD)
blink, indicating communication between your router and your ISP. The browser
then displays its opening page. This process may take up to a minute.
After about five minutes of inactivity, the router disconnects the call.
Troubleshooting Information
FirstGear cannot find your router:
•
Check the Ethernet connection between your PC and router. The Link LED
on your Ethernet card and the corresponding port LED on the router should
be lit.
•
Power cycle the router. Wait 1 minute before starting FirstGear.

ISDN connection test fails:
•
•
•
Check that you entered the directory numbers in a correct format. Do not
enter the area code unless it is required.
Recheck your directory numbers, SPIDs, and switch type (North America
only).
For North America: If the switch at your phone company is running the
National ISDN (NI-1) protocol, select “National ISDN” rather than the
switch model (Nortel, AT&T).
ISP connection test fails:
•
Check that you entered the phone number in the correct format. Do not enter
the area code unless required.
Note: In some areas of North America only, you must dial an ISDN
data call using 1+ (area code) or you will receive a 56K connection
instead of a 64K connection.
Router does not place a call when you launch your browser:
•
Make sure your PC has the router configured as its default gateway. Verify
the gateway as described in the section “Verifying TCP/IP Properties” in
this document.
•
If your PC launches the Dial-Up Networking program, change the Internet
connection parameters:
a. Access the Internet Control Panel.
b. Select the Connection tab.
c. Depending on the Dial-Up Networking program, either:
•
•
Uncheck the check box labeled “Connect to the Internet as needed.”
Uncheck the check box labeled “Connect to the Internet using a
local area network.”
Your router connects, but you cannot load any pages from the Internet:
•
Make sure your PC has one DNS server address configured. A DNS server
is an Internet host that translates Internet names (such as “www” addresses)
to numeric IP addresses. Typically, your ISP provides the addresses of one
or two DNS servers for use. Follow the steps described in “Verifying TCP/
IP Properties” to verify that a DNS server address is present.
