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

–

Idle Timeout

. Your Internet connection is logged out if there is no data transfer during the

specified time interval.

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,
