If your ISP has assigned you a permanent, fixed (static) IP address for your computer,
select
Use Static IP Address
. Enter the IP address that your ISP assigned. Also, enter
the subnet mask and the gateway IP address. The gateway is the ISP’s router to which
your router will connect.
–
Domain Name Server (DNS) Address
. If you know that your ISP does not automatically
transmit DNS addresses to the router during login, select
Use These DNS Servers
, and
enter the IP address of your ISP’s primary DNS server. If a secondary DNS server address
is available, enter it also.
–
Router MAC Address
. This section determines the Ethernet MAC address that the router
will use on the Internet port. Typically, you would leave
Use Default Address
selected.
However, some ISPs (especially cable modem providers) register the Ethernet MAC
address of the network interface card in your computer when your account is first opened.
They then accept only traffic from the MAC address of that computer. This feature allows
your router to masquerade as that computer by “cloning” or “spoofing” its MAC address.
To change the MAC address, select one of the following methods:
•
Select
Use Computer MAC Address
. The router will then capture and use the MAC
address of the computer that you are now using. You must be using the one computer
that is allowed by the ISP.
•
Select
Use This MAC Address
, and type it in here.
–
Does Your Internet Connection Require A Login?
. If you usually must use a login
program such as WinPOET to access the Internet, your Internet connection requires a
login. After you select
Yes
, the Basic Settings screen displays, as shown in the following
figure.
Note:
If you enter or change a DNS address, restart the computers on your
network so that these settings take effect.
Note:
After you finish setting up your router, you will no longer need to start the
ISP’s login program on your computer to access the Internet. When you
start an Internet application, your router will automatically log you in.

Note:
The Telstra Bigpond setting is only for older cable modem service
accounts that still require a Bigpond Login utility. Telstra has discontinued
this type of account. Those with Telstra DSL accounts and newer cable
modem accounts should select

Choosing Appropriate Wireless Security
Unlike wired networks, wireless networks allow anyone with a compatible adapter to receive your
wireless data transmissions well beyond your walls. Operating an unsecured wireless network
creates an opportunity for outsiders to eavesdrop on your network traffic or to enter your network
to access your computers and files. Indoors, computers can connect over 802.11g/n wireless
networks at ranges of up to 300 feet. Such distances can allow for others outside your immediate
area to access your network. Use the security features of your wireless equipment that are
appropriate to your needs.
The time it takes to establish a wireless connection can vary depending on both your security
settings and router placement.
Stronger security methods can entail a cost in terms of throughput, latency, battery consumption,
and equipment compatibility. In choosing an appropriate security level, you can also consider the
effort compared to the reward for a hacker to break into your network. As a minimum, however,
