User’s Manual for the NETGEAR Super AG Wireless USB 2.0 Adapter WG111U
Appendix C-18 Preparing Your Network to Work with a Router
202-10065-01
In order to share the Internet connection among several computers, your router takes the place of
the single computer, and you need to configure it with the TCP/IP information that the single
computer would normally use. When the routers Internet port is connected to the broadband
modem, the router appears to be a single computer to the ISP. The router then allows the computers
on the local network to masquerade as the single computer to access the Internet through the
broadband modem. The method used by the router to accomplish this is called Network Address
Translation (NAT) or IP masquerading.
Are Login Protocols Used?
Some ISPs require a special login protocol, in which you must enter a login name and password in
order to access the Internet. If you normally log in to your Internet account by running a program
such as WinPOET or EnterNet, then your account uses Point-to-Point Protocol over Ethernet
(PPPoE).
When you configure your router, you need to enter your login name and password in the routers
configuration menus. After your network and router are configured, the router will perform the
login task when needed, and you will no longer need to run the login program from your computer.
It is not necessary to uninstall the login program.
What Is Your Configuration Information?
More and more, ISPs are dynamically assigning configuration information. However, if your ISP
does not dynamically assign configuration information but instead used fixed configurations, your
ISP should have given you the following basic information for your account:
An IP address and subnet mask
A gateway IP address, which is the address of the ISP’s router
One or more domain name server (DNS) IP addresses
Host name and domain suffix
For example, your account’s full server names may look like this:
mail.xxx.yyy.com
In this example, the domain suffix is xxx.yyy.com.
If any of these items are dynamically supplied by the ISP, your router automatically acquires them.
