Chapter 2: Planning Your Network

IP Addresses

Wireless-G ADSL Home Gateway

Since you use the Gateway to share your DSL Internet connection, contact your ISP to find out if they have

assigned a static IP address to your account. If so, you will need that static IP address when configuring the

Gateway. You can get that information from your ISP.

Dynamic IP Addresses

A dynamic IP address is automatically assigned to a device on the network, such as computers and print servers.

These IP addresses are called “dynamic” because they are only temporarily assigned to the computer or device.

After a certain time period, they expire and may change. If a computer logs onto the network (or the Internet) and

its dynamic IP address has expired, the DHCP server will automatically assign it a new dynamic IP address.

DHCP (Dynamic Host Configuration Protocol) Servers

Computers and other network devices using dynamic IP addressing are assigned a new IP address by a DHCP

server. The computer or network device obtaining an IP address is called the DHCP client. DHCP frees you from

having to assign IP addresses manually every time a new user is added to your network.

A DHCP server can either be a designated computer on the network or another network device, such as the

Gateway. By default, the Gateway’s DHCP Server function is enabled.

If you already have a DHCP server running on your network, you must disable one of the two DHCP servers. If you

run more than one DHCP server on your network, you will experience network errors, such as conflicting IP

addresses. To disable DHCP on the Gateway, see the DHCP section in “Chapter 5: Configuring the Wireless-G

ADSL Home Gateway.”

The Gateway's LEDs, which indicate network activity, are located on the other side panel.

POWER

Green. The

POWER

LED lights up when the Gateway is powered on.

WIRELESS

Green. The

WIRELESS

LED lights up whenever there is a successful wireless connection. If the

LED is flashing, the Gateway is actively sending or receiving data to or from one of the devices

on the network.

ETHERNET (1-4)

Green. The

ETHERNET

LED serves two purposes. If the LED is continuously lit, the Gateway is

successfully connected to a device through the LAN port. If the LED is flashing, it is an

indication of any network activity.

DSL

Green. The

DSL

LED lights up whenever there is a successful DSL connection. The LED blinks

while the Gateway is establishing the ADSL connection.

INTERNET

Green. The

INTERNET

LED lights up green when an Internet connection to the Internet Service

Provider (ISP) is established. The

INTERNET

LED lights up red when the connection to the ISP

fails.

The Gateway comes with a built-in antenna; however, you can attach an optional antenna. (Note: This antenna is

currently not available in Europe.) The Linksys 5dBi High Gain Antenna for SMA Connectors (model number:

HGA5S) is available for increased range. The Gateway’s SMA port for the optional antenna is located on the top

panel. To access the SMA port, push the tab. To attach the antenna, insert the base of the antenna into the SMA

port and tighten it clockwise by hand.

The Gateway has a built-in stand available. If you place the Gateway flat on a surface, then you can leave the

stand in the closed position. However, if you want the Gateway to be upright, swivel the stand clockwise 90º and

position the Gateway accordingly.
