If an IP address appears under Installed Gateways, write down the address. This is the ISP’s

gateway address. Select the address and then click Remove to remove the gateway address.

6.

Select the DNS Configuration tab.

If any DNS server addresses are shown, write down the addresses. If any information appears

in the Host or Domain information box, write it down. Click Disable DNS.

7.

Click OK to save your changes and close the TCP/IP Properties dialog box.

You are returned to the Network window.

8.

Click OK.

9.

Reboot your PC at the prompt. You may also be prompted to insert your Windows CD.

Obtaining ISP Configuration Information for Macintosh

Computers

As mentioned above, you may need to collect configuration information from your Macintosh so

that you can use this information when you configure the WGT624 v2 wireless router. Following

this procedure is only necessary when your ISP does not dynamically supply the account

information.

To get the information you need to configure the firewall for Internet access:

1.

From the Apple menu, select Control Panels, then TCP/IP.

The TCP/IP Control Panel opens, which displays a list of configuration settings. If the

“Configure” setting is “Using DHCP Server”, your account uses a dynamically-assigned IP

address. In this case, close the Control Panel and skip the rest of this section.

2.

If an IP address and subnet mask are shown, write down the information.

3.

If an IP address appears under Router address, write down the address. This is the ISP’s

gateway address.

4.

If any Name Server addresses are shown, write down the addresses. These are your ISP’s DNS

addresses.

5.

If any information appears in the Search domains information box, write it down.

6.

Change the “Configure” setting to “Using DHCP Server”.

7.

Close the TCP/IP Control Panel.

Restarting the Network

Once you’ve set up your computers to work with the firewall, you must reset the network for the

devices to be able to communicate correctly. Restart any computer that is connected to the firewall.

After configuring all of your computers for TCP/IP networking and restarting them, and

connecting them to the local network of your WGT624 v2 wireless router, you are ready to access

and configure the firewall.

Wireless Networking Basics

This chapter provides an overview of Wireless networking.

Wireless Networking Overview

The WGT624 v2 wireless router conforms to the Institute of Electrical and Electronics Engineers

(IEEE) 802.11 standard for wireless LANs (WLANs) and a product update will bring the WGT624

v2 into conformance to the 802.11g standard when it is ratified. On an 802.11b or g wireless link,

data is encoded using direct-sequence spread-spectrum (DSSS) technology and is transmitted in

the unlicensed radio spectrum at 2.5GHz. The maximum data rate for the wireless link is 11 Mbps,

but it will automatically back down from 11 Mbps to 5.5, 2, and 1 Mbps when the radio signal is

weak or when interference is detected. The 802.11g auto rate sensing rates are 1, 2, 5.5, 6, 9, 12,

18, 24, 36, 48, and 54 Mbps.

The 802.11 standard is also called Wireless Ethernet or Wi-Fi by the Wireless Ethernet

Compatibility Alliance (WECA, see

http://www.wi-fi.net

), an industry standard group promoting

interoperability among 802.11 devices. The 802.11 standard offers two methods for configuring a

wireless network - ad hoc and infrastructure.

Infrastructure Mode

With a wireless Access Point, you can operate the wireless LAN in the infrastructure mode. This

mode provides wireless connectivity to multiple wireless network devices within a fixed range or

area of coverage, interacting with wireless nodes via an antenna.

In the infrastructure mode, the wireless access point converts airwave data into wired Ethernet

data, acting as a bridge between the wired LAN and wireless clients. Connecting multiple Access

Points via a wired Ethernet backbone can further extend the wireless network coverage. As a

mobile computing device moves out of the range of one access point, it moves into the range of

another. As a result, wireless clients can freely roam from one Access Point domain to another and

still maintain seamless network connection.

Ad Hoc Mode (Peer-to-Peer Workgroup)

In an ad hoc network, computers are brought together as needed; thus, there is no structure or fixed

points to the network - each node can generally communicate with any other node. There is no

Access Point involved in this configuration. This mode enables you to quickly set up a small

wireless workgroup and allows workgroup members to exchange data or share printers as

supported by Microsoft networking in the various Windows operating systems. Some vendors also

refer to ad hoc networking as peer-to-peer group networking.

In this configuration, network packets are directly sent and received by the intended transmitting

and receiving stations. As long as the stations are within range of one another, this is the easiest

and least expensive way to set up a wireless network.

Network Name: Extended Service Set Identification (ESSID)

The Extended Service Set Identification (ESSID) is one of two types of Service Set Identification

(SSID). In an ad hoc wireless network with no access points, the Basic Service Set Identification

(BSSID) is used. In an infrastructure wireless network that includes an access point, the ESSID is

used, but may still be referred to as SSID.

An SSID is a thirty-two character (maximum) alphanumeric key identifying the name of the

wireless local area network. Some vendors refer to the SSID as network name. For the wireless

devices in a network to communicate with each other, all devices must be configured with the

same SSID.
