Telephone Line Checklist
The Model RM356 Modem Router connects to the Public Switched Telephone Network (PSTN)
using a standard analog voice line. When ordering telephone service, the following information
should be verified:
Line Quality
Though the modem is capable of 56 Kbps download performance, the condition of your
telephone line and your local public telephone infrastructure may limit your actual data rate.
For example:
FCC rules limit the data rate to 53 Kbps in the United States.
The use of repeaters between your premises and the central office will limit your
performance to 33 Kbps.
If your data rate is substantially less than 50 Kbps, you may want to consult your telephone
company regarding the quality of your line.
Calling Line Identification (CLID)
If you require CLID for security, you must order CLID for your line from your local carrier.
ISP Checklist
If you will be contracting with an Internet service provider (ISP) for Internet access, you must
choose between a single-user account and a multiuser LAN account. You can connect a multiuser
network through a single-user account by using the Network Address Translator (NAT) feature of
your router.
Single-User Account
In a single-user account, you are assigned only one registered Internet Protocol (IP) address. This
address may be a permanent fixed address or it may be a different address assigned dynamically
each time you log in to the account. The NAT feature of your router will map the IP addresses of
your network to this address for accessing the Internet. Some applications may be incompatible
with NAT.
LAN Account
In a LAN account, you will be assigned a registered IP address for your router and one for each
PC or workstation in your local network. A LAN account is typically more expensive than a
single-user account.
Account Information
Your ISP should give you the following basic information for your account whether it is a singleuser or LAN account:
A local phone number for accessing the ISP
A login name
A password
IP address(es) unless dynamically assigned
DNS server IP address(es) of the ISP
Model RM356 Modem Router Installation Guide
Network Checklist
The Model RM356 Modem Router uses the Internet Protocol (IP). The IP configuration has the
following requirements:
All PCs must have TCP/IP manually installed and manually selected as the networking protocol. See “Configuring TCP/IP” for further instructions.
All PCs and the router must be assigned IP addresses. If your ISP or network administrator
has not assigned these, use private addresses as described below. If you are using the default
Dynamic Host Configuration Protocol (DHCP) function of the router, these private addresses
are assigned automatically by the router when the PCs are rebooted.
All PCs must have the IP address of the router defined as the default gateway. If you are using
the default DHCP function of the router, this IP address is assigned automatically by the
router when the PCs are rebooted.
Using Private Internet Protocol (IP) Addresses
If you will be using the private addressing scheme recommended by NETGEAR, your IP
addresses will be assigned as follows:
•—local IP address of your router and default gateway for the PCs
• through—IP addresses of your PCs
•—netmask for your router and PCs
This information may be entered manually to each device or it may be assigned automatically by
the default DHCP function of the router when the PCs are rebooted.
Connecting the Router
Connect the router to a power source, to your local area network (LAN), and to your telephone
line as shown in “Hardware Installation.”
For your telephone line connection, use the black cable provided.
For your LAN connection, use the white straight-through cable provided to connect your Model
RM356 router either to a PC or to the Uplink port of an Ethernet hub.

Configuring TCP/IP Properties Manually
If you choose not to configure your PC by DHCP, you must manually enter the following
information in the TCP/IP Properties section of the Network Control Panel of your PC:
IP address and subnet mask (choose from your assigned IP addresses or private IP addresses)
Gateway (enter the IP address of the router)
DNS server addresses (enter IP addresses provided by your ISP)
Verifying TCP/IP Properties
After your PC has been configured and rebooted, you can check the TCP/IP configuration using
the Windows utility winipcfg.exe (for Windows NT® systems, use ipconfig.exe). From the “Start”
button, open the Run window, type winipcfg, and click on “OK.”
Note: In addition to displaying the current TCP/IP properties, the winipcfg utility allows
you to release and renew DHCP-assigned information without rebooting the PC.

Model RM356 Modem Router Installation Guide
Accessing the Internet
Accessing the Internet
When your router and PCs are configured correctly, your router places a call automatically
whenever an application requires access to the Internet. The router also disconnects from the
Internet when the connection has been idle for a period of time. It is not necessary for you to run a
dialer application such as Dial-Up Networking to connect, log in, or disconnect. These functions
are performed by the router as needed.
To access the Internet, launch a browser application such as Microsoft Internet Explorer or
Netscape Navigator. On the router, you should see the Offhook (OH) LED illuminate, followed
shortly by the Carrier Detect (CD) LED. Soon the data transmit and receive LEDs (TD and RD)
will begin to flicker, indicating communication between your router and your ISP. The browser
should then begin to display a page. This process may take up to one minute.
After about five minutes of inactivity, the router will disconnect the call. Upon further browser
activity, the router will redial automatically.
Common Problems
Common Problems
Here are a few common problems and likely causes:
If 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 on.
If the connection test fails after the Quick Configuration, look in the displayed trace for
details. Recheck your ISP account phone number, login name, and password.
If the router does not place a call when you launch your browser, your PC might not
have the router configured as its TCP/IP gateway. If the PC gets its information from the
router by DHCP, reboot the PC and verify the gateway address as described in
“Verifying TCP/IP Properties.”
If the router connects but you cannot load pages from the Internet, the PC might not
know any DNS server addresses. A DNS server is a host on the Internet that translates
Internet names (such as www addresses) to numeric IP addresses. Typically your ISP
will provide the addresses of one or two DNS servers for your use. If you entered a DNS
address during the Quick Configuration, reboot your PC and verify the DNS address as
described in “Verifying TCP/IP Properties.” You can also configure your PC manually
with DNS addresses as explained in “Configuring TCP/IP.”
More detailed information can be found in the Troubleshooting sections of Reference Guide for
the Model RM356 Modem Router and Getting Started Using FirstGear for the Model RM356
Modem Router.
