Understanding WG602 v3 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 v3 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 v3 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 v3. 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 v3
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 v3, 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 v3 in a high location, first set up and test the WG602 v3 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 v3 to the PC (

d.
Turn on your computer, connect the power adapter to the WG602 v3 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 v3 is set by default to be a DHCP client. So, if the WG602 v3 has not yet been
installed, and there is no DHCP server on the network, you can log in to the WG602 v3 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 v3 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 v3
Using Its Default NetBIOS Name” on page 3-9
.
2.
Open a Web browser such as Internet Explorer or Netscape Navigator.
3.
Connect to the WG602 v3 by entering its default address of
into your
browser.

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 v3 in your
network. If needed, you can now reconfigure the PC you used in step 1 back to its original
TCP/IP settings.

Disconnect the WG602 v3 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 v3 Access Point to a LAN port on your
router, switch, or hub.
Note:
By default, WG602 v3 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 v3 (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
“Troubleshooting” on page 6-1
.
Two Ways to Log In to the WG602 v3
The 54 Mbps Wireless Access Point WG602 v3 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 v3 in these two ways:
•
Using the Default IP Address of the WG602 v3 is the most reliable.
•
Using the NetBIOS name of the WG602 v3 is not as reliable as using the IP Address.
The procedures for these two ways of logging in to the WG602 v3 are presented here.

How to Log in Using the Default IP Address of the WG602 v3
1.
192.168.0.227 is the default IP address of your access point. However, the WG602 v3 is also
set, by default, to be a DHCP client. So, if the WG602 v3 has not yet been installed, and there
is no DHCP server on the network, you can log in to the WG602 v3 using its default IP
address. Otherwise, you should use either the NetBIOS login described in
“How to Log In to
the WG602 v3 Using Its Default NetBIOS Name” on page 3-9
or the procedure described in
“Set up the WG602 v3 Access Point” on page 3-4
” which uses a static IP configuration.
Note:
The computer you are using to connect to the WG602 v3 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 v3 by entering its default address of
into your
browser.
4.
A login window like the one shown below opens:
Figure 3-4: Login window
Log in use the default user name of

.
Once you have entered your access point name, your Web browser should automatically find
the WG602 v3 Access Point and display the home page, as shown in
“Login result: WG602 v3
home page” on page 3-8
.
