PREPARATION AND SETUP
Before using the router to connect your LAN to the Internet, you must:
•Order Internet service from an Internet service provider (ISP)
•Set up your PCs for using theTransmission Control Protocol/Internet Protocol (TCP/IP)
networking protocol
ISP Checklist
Contact an ISP to request a single-user Internet access account that provides a broadband access device,
such as a cable modem or DSL modem, to connect the router to the Internet.You can connect a multi-
user LAN through a single-user account by using the Network AddressTranslation (NAT) feature of the
router.The modem must have a standard Ethernet interface to connect to your router.
In a single-user account,you are assigned only one registered IP address.This address may be a perma-
nent, fixed address or it may be an address assigned dynamically when your modem connects to the ISP.
The NAT feature of your router will map the IP addresses of your PCs to this address for accessing the
Internet. Some applications may be incompatible with NAT.
Account Information
Unless the following information is dynamically assigned,your ISP should provide you with this basic
account information:
•IP address
•Subnet mask
•Domain name system (DNS) server IP addresses
•Gateway IP address
•Host name and domain name
Your account’s full server names may look like this:
mail.xxx.yyy.com
In this example, the domain name is xxx.yyy.com
If an ISP technician configures your PC during modem installation, you may need to obtain the account
information from your PC’s network setup. Refer to the Reference Guide for the Model RT311 and
RT314 Internet Access Gateway Routers , on the Model RT311 and RT314 Resource CD , for informa-
tion about this procedure.
Determine whether your account uses a special login protocol:
•If your ISP uses PPP over Ethernet (PPPoE), you will need a login name and password,
and you will need to select PPPoE in the router configuration.
•If your ISP is RoadRunner, you should ask whether your PC must run a RoadRunner
login program.

PREPARATION AND SETUP CONT.
Network Checklist
The Model RT311 Internet Access Gateway Router uses IP. IPconfiguration has the
following requirements:
•All PCs must have TCP/IP manually installed and selected as the networking protocol.
•All PCs and the router must be assigned IP addresses.The router’s DHCP function
automatically assigns IP addresses for you, but the PC’s IP address must be set to
“Obtain an IP address automatically”in the Network Control Panel.
•Check that “Obtain an IP address automatically”is selected in theTCP/IP properties in
the Network Control Panel.Refer to “ConfiguringTCP/IP”in the next section to confirm
these settings.
CONFIGURING TCP/IP

Configuring TCP/IP Properties
NETGEAR recommends that you leave theTCP/IP setup parameters at their factory default settings
unless you have a specific reason to change them.With the default settings,your PC is configured to
obtain itsTCP/IP configuration information automatically from a DHCP server on the local network.
The Model RT311 Internet Access Gateway Router is shipped preconfigured as a DHCP server, and will
assign theTCP/IP configuration information described in the following section.
You must also be certain that your PC is set to “Obtain an IP address automatically”in the Network
Control Panel.
To confirm that the IP address will be automatically obtained:
1. Click on Start from the Windows toolbar.
2. Select Settings; then select Control Panel.
3. Double-click on Network.
4. Select the Configuration tab.
5. From the list of network components, select TCP/IP.
If you have severalTCP/IP entries in the network components list, choose the one associated
with the Ethernet adapter in your PC.
6. Click on Properties.
TheTCP/IP menu is displayed.
7. Select the IP address tab, as shown below.

8. Select Obtain an IP address automatically.
9. Click on OK.
To obtain the configuration information from the router:
1. Turn on the router. Be sure the router has been on for at least one minute before continuing to the
next step.
2. Reboot each PC on your network.
Verifying TCP/IP Properties
After your PC has been configured and rebooted, you can check theTCP/IP configuration using the
Windows utility winipcfg.exe (or for Windows NT®systems, use ipconfig.exe ). From the Start button,
open the Run window, type winipcfg at the prompt,and click on OK.In the winipcfg display window,
select your Ethernet adapter from the drop-down menu, and verify that:
•The IP address of the PC is between 192.168.0.2 and 192.168.0.31.
•The subnet mask is 255.255.255.0.
•The default gateway is 192.168.0.1.
Click on More Info, and verify that:
•The DNS server IP address is 192.168.0.1.
