Understanding WG602 v2 Wireless Security Options

Unlike wired network data, your wireless data transmissions can be received well beyond your

walls by anyone with a compatible adapter. For this reason, use the security features of your

wireless equipment. The WG602 v2 Access Point provides highly effective security features

which are covered in detail in this chapter. Deploy the security features appropriate to your needs.

Figure 3-1: WG602 v2 wireless data security options

There are several ways you can enhance the security of your wireless network:

•

Restrict Access Based on MAC Address.

You can restrict access to only trusted PCs so that

unknown PCs cannot wirelessly connect to the WG602 v2. MAC address filtering adds an

obstacle against unwanted access to your network, but the data broadcast over the wireless link

is fully exposed.

•

Turn Off the Broadcast of the Wireless Network Name (SSID).

If you disable broadcast of

the SSID, only devices that have the correct SSID can connect. This nullifies the wireless

network ‘discovery’ feature of some products such as Windows XP, but the data is still fully

exposed to a determined snoop using specialized test equipment like wireless sniffers.

•

Use WEP.

Wired Equivalent Privacy (WEP) data encryption provides data security. WEP

Shared Key authentication and WEP data encryption will block an eavesdropper but because

the keys are static, a determined snoop can learn the keys in less than a day of eavesdropping.

•

Use WPA-PSK.

Wi-Fi Protected Access (WPA) data encryption provides data security.

WPA-PSK will block eavesdropping. Because this is a new standard, wireless device driver

and software availability may be limited. However, WPA is not available in bridge mode.

1) Open System: Easy but no security

2) MAC Access List: No data security

3) WEP:

Secure but some vulnerabilities

4) WPA:

Very strong security

Installing the 54 Mbps Wireless Access Point WG602 v2

Follow the instructions below to set up and test basic wireless connectivity. Once you have

established basic wireless connectivity, you can enable security settings and configure the

advanced wireless functions.

Before installing the 54 Mbps Wireless Access Point WG602 v2, you should make sure that your

Ethernet network is up and working. You will be connecting the access point to the Ethernet

network so that computers with 802.11b or 802.11g wireless adapters will be able to communicate

with computers on the Ethernet network. In order for this to work correctly, verify that you have

met all of the system requirements, shown on

page 2-3

.

Tip:

Before mounting the WG602 v2 in a high location, first set up and test the WG602 v2 to

verify wireless network connectivity.

a.

Prepare a PC with an Ethernet adapter. If this PC is already part of your network, record its

TCP/IP configuration settings.

b.

Configure the PC with a static IP address of 192.168.0.210 and 255.255.255.0 for the

Subnet Mask.

c.

Connect an Ethernet cable from the WG602 v2 to the PC (

d.

Turn on your computer, connect the power adapter to the WG602 v2 and verify the

following:

The power light goes on.

The LAN light of the wireless access point is lit when connected to a powered on PC.

above on your computer.

1.

The WG602 v2 is set by default to be a DHCP client. So, if the WG602 v2 has not yet been

installed, and there is no DHCP server on the network, you can log in to the WG602 v2 using

its default IP address. 192.168.0.227 is the default IP address of your access point.

Note

: This procedure which uses a static IP configuration. If WG602 v2 has already been

installed or it is connected to a network where there as a DHCP server as commonly found in

home routers, you can the NetBIOS login described in

“How to Log In to the WG602 v2

Using Its Default NetBIOS Name” on page 3-8

.

2.

Open a Web browser such as Internet Explorer or Netscape Navigator.

3.

Connect to the WG602 v2 by entering its default address of

Note:

You must set the Regulatory Domain. It may not be legal to operate the wireless

access point in a region other than one of those identified in this field.

Now that you have finished the setup steps, you are ready to deploy the WG602 v2 in your

network. If needed, you can now reconfigure the PC you used in step 1 back to its original

TCP/IP settings.

a.

Disconnect the WG602 v2 and position it where you will deploy it. The best location is

elevated at the center of your wireless coverage area.

b.

Lift the antenna side so that it is vertical.

c.

Connect an Ethernet cable from your WG602 v2 Access Point to a LAN port on your

router, switch, or hub.

Note:

By default, WG602 v2 is set to be a DHCP client. If your network uses static IP

addresses, you will need to change this setting.

d.

Connect the power adapter to the wireless access point and plug the power adapter in to a

Using a computer with an 802.11b or 802.11g wireless adapter with the correct wireless

settings needed to connect to the WG602 v2 (SSID, MAC ACL, WEP, WPA, etc.), verify

connectivity by using a browser such as Netscape or Internet Explorer to browse the Internet,

or check for file and printer access on your network. If you cannot connect, see

Two Ways to Log In to the WG602 v2

The 54 Mbps Wireless Access Point WG602 v2 can be configured remotely from Microsoft

Internet Explorer browser version 5.0 or above, or Netscape Navigator Web browser version 4.78

or above. You can log in to the WG602 v2 in these two ways:

•

Using the Default IP Address of the WG602 v2 is the most reliable.

•

Using the NetBIOS name of the WG602 v2 is not as reliable as using the IP Address.

The procedures for these two ways of logging in to the WG602 v2 are presented here.

How to Log in Using the Default IP Address of the WG602 v2

1.

192.168.0.227 is the default IP address of your access point. However, the WG602 v2 is also

set, by default, to be a DHCP client. So, if the WG602 v2 has not yet been installed, and there

is no DHCP server on the network, you can log in to the WG602 v2 using its default IP

address. Otherwise, you should use either the NetBIOS login described in

“How to Log In to

the WG602 v2 Using Its Default NetBIOS Name” on page 3-8

or the procedure described in

“Set up the WG602 v2 Access Point” on page 3-4

” which uses a static IP configuration.

Note:

The computer you are using to connect to the WG602 v2 should be configured with an

IP address that starts with 192.168.0.x and a Subnet Mask of 255.255.255.0.

2.

Open a Web browser such as Internet Explorer or Netscape Navigator.

3.

Connect to the WG602 v2 by entering its default address of

into your

browser.

4.

A login window like the one shown below opens:
