Reference Guide for the Model RT311 and RT314 Internet Access Gateway Routers

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. In the winipcfg display window,
select your Ethernet adapter. If you are using the default TCP/IP settings recommended by
NETGEAR, the following information will appear:
• The IP address should be between 192.168.0.2 and 192.168.0.31.
• The subnet mask should be 255.255.255.0.
• The default gateway should be 192.168.0.1.
Click on More Info, and verify the following:
• The DNS server should be 192.168.0.1.

Your Internet Account

You must contract with an Internet service provider (ISP) for a single-user Internet access account.
You can connect your multiuser network through a single-user account by using the Network
Address Translation (NAT) feature of your router. In a single-user account, your ISP assigns only
one registered Internet Protocol (IP) address for your use. With most accounts, this address is
assigned dynamically when your PC is first booted up while connected to the ISP, and you will not
need to know the actual address. The NAT feature of your router translates the private IP addresses
of your network PCs to this address for accessing the Internet.

Login Protocols

Some ISPs require a special login protocol. In this case, you will need to know what type of
protocol is used, and you will need a login name and password. The two common protocols are:
• PPP over Ethernet (PPPoE)
• RoadRunner
Not all RoadRunner service areas require a login protocol. If your ISP is RoadRunner, you
should ask whether your PC must run a RoadRunner login program.
