Chapter 4
Optimizing Wireless Connectivity and Security
This chapter describes how to configure the wireless features of your wireless router. In planning
your wireless network, you should consider the level of security required. You should also select
the physical placement of your firewall in order to maximize the network speed.
The full manual with detailed how to instructions is available on line at
http://kbserver.netgear.com/documentation/wgu624.asp and via the Documentation link in the
configuration utility of the wireless router.
Observe Performance, Placement, and Range Guidelines
The operating distance or range of your wireless connection can vary significantly bas ed on the
physical placement of the wireless firewall. The latency, data throughput performance, and
notebook power consumption of wireless adapters also vary depending on your configuration
choices.
Note: Failure to follow these guidelines can result in significant performance
degradation or inability to wirelessly connect to the router. For complete range/
performance specifications, please see Appendix A, “Technical Specifications.”
For best results, place your firewall:
• Near the center of the area in which your computers will operate.
• In an elevated location such as a high shelf where the wirelessly connected computers have
line-of-sight access (even if through walls).
• Away from sources of interference, such as computers, microwaves, and 2.4 GHz cordless
phones.
• Away from large metal surfaces.
The time it takes to establish a wireless connection can vary depending on both your security
settings and placement. WEP connections can take slightly longer to establish. Also, WEP
encryption can consume more battery power on a notebook computer.

Implement Appropriate Wireless Security
Note: Indoors, computers can connect over 802.11b/g wireless networks at ranges of up
to 300 feet. Such distances can allow for others outside of your immediate area to access
your network.
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 wireless router provides highly effective security features which are
covered in detail in this chapter. Deploy the security features appropriate to your nee ds .
Figure 4-1: wireless router wireless dat a 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 computers
so that unknown computers cannot wirelessly connect to the wireless router. 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.
• WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared
Key authentication and WEP data encryption will block all but the most determined
eavesdropper.
4-2 Optimizing Wireless Connectivity and Security
August 2004
NETGEAR Wireless Router Setup Manual
• WPA-PSK. Wi-Fi Protected Access (WPA) data encryption provides strong data security.
WPA-PSK will block eavesdropping. Because this is a new standard, wireless device driver
and software availability may be limited.
• Turn Off the Wired LAN. If you disable the wireless LAN, wireless devices cannot
communicate with the router at all. You might choose to turn off the wireless the LAN when
you are away and the others in the household all use wired connections.
Understanding Wireless Settings
T o configure the Wireless settings of your firewall, click the Wireless link in the main menu of the
browser interface.
• Name (SSID). The SSID is also known as the wireless network name. Enter a value of up to
32 alphanumeric characters. In a setting where there is more than one wireless network,
different wireless network names provide a means for separating the traffic. Any device you
want to participate in a particular wireless network will need to use this SSID for that network.
• Region. This field identifies the region where the wireless router can be used. It may not be
legal to operate the wireless features of the wireless router in a region other than one of those
identified in this field.
• Channel. This field determines which operating frequency will be used. It should not be
necessary to change the wireless channel unless you notice interference problems with another
nearby access point.
• Mode. This field determines which data communications protocol will be used.
• Security Options. These options are the wireless security features you can enable. The table
below identifies the various basic wireless security options.
• Allow Broadcast of Name (SSID). If you disable broadcast of the SSID, only devices that
have the correct SSID can connect. Disabling SSID broadcast nullifies the wireless network
‘discovery’ feature of some products such as Windows XP.
• Enable Wireless Access Point. If you disable the wireless access point, wireless devices
cannot connect to the wireless router.
• Wireless Card Access List. When the Trusted PCs Only radio button is selected, the wireless
router checks the MAC address of the wireless station and only allows connections to
computers identified on the trusted computers list.

With Open Network Authentication and 64- or 128-bit WEP Data Encryption, the wireless
router does perform 64- or 128-bit data encryption but does not perform any authentication.
• Shared Key
Shared Key authentication encrypts the SSID and data.
Choose the Encryption Strength (64- or 128-bit data encryption). Manually enter the key
values or enter a word or group of printable ch aracters in the Passphrase box. Manually
entered keys are case sensitive but passphrase characters are not case sensitive.
Note: Not all wireless adapter configuration utilities support passphrase key generation.
•Auto
dynamically changes the encryption keys making it nearly impossible to circumvent.
Enter a word or group of printable characters in the Password Phrase box. These characters
are case sensitive.
Note: Not all wireless adapter configuration utilities support WPA. Furthermore, client software
is required on the client. Windows XP and Windows 2000 with Service Pack 3 do include the
client software that supports WPA. Nevertheless, the wireless adapter hardware and driver
must also support WPA.

Chapter 6
Troubleshooting Common Problems
This chapter gives information about troubleshooting your Wireless Router. After each problem
description, instructions are provided to help you diagnose and solve the problem.
Basic Functioning
After you turn on power to the router, the following sequence of events should occur:
1. When power is first applied, verify that the Power light is on.
2. After approximately 10 seconds, verify that:
a. The power light is solid green.
b. The LAN port lights are lit for any local ports that are connected.
c. The Internet port light is lit.
If a port’s light is lit, a link has been established to the connected device. If a LAN port is
connected to a 100 Mbps device, verify that the port’ s light is green. If the port is 10 Mbps, the
light will be amber.
If any of these conditions does not occur, refer to the appropriate following section.
Power Light Not On
If the Power and other lights are off when your router is turned on:
• Make sure that the power cord is properly connected to your router and that the power supply
adapter is properly connected to a functioning power outlet.
• Check that you are using the 5V DC @ 2.8A output power adapter supplied by NETGEAR for
this product.
If the error persists, you have a hardware problem and should contact technical support.
Troubleshooting Common Problems 6-1
August 2004
NETGEAR Wireless Router Setup Manual
Lights Never Turn Off
When the router is turned on, the lights turns on for about 10 seconds and then turn off. If all the
lights stay on, there is a fault within the router.
If all lights are still on one minute after power up:
• Cycle the power to see if the router recovers.
• Clear the router’s configuration to factory defaults. This will set the router’s IP address to
192.168.1.1. This procedure is explained in “Restoring the Default Configuration and
Password” on page 6-7.
If the error persists, you might have a hardware problem and should contact technical support.
LAN or Internet (WAN) Port Lights Not On
If either the LAN lights or Internet light do not light when the Ethernet connection is made, check
the following:
• Make sure that the Ethernet cable connections are secure at the router and at the hub or
workstation.
• Make sure that power is turned on to the connected hub or workstation.
• Be sure you are using the correct cable:
— When connecting the router’s Internet port to a cable or DSL modem, use the cable that
was supplied with the cable or DSL modem. This cable could be a standard
straight-through Ethernet cable or an Ethernet crossover cable.
Troubleshooting the Web Configuration Interface
If you are unable to access the router’s Web Configuration interface from a computer on your local
network, check the following:
• Check the Ethernet connection between the computer and the router as described in the
previous section.
6-2 T ro ub lesh oo tin g Co mm o n Proble m s
August 2004
NETGEAR Wireless Router Setup Manual
• Make sure your computer’s IP address is on the same subnet as the router. If you are using the
default addressing schemes, your computer’s address should be in the range of 192.168.1.2 to
192.168.1.254. Refer to “Verifying TCP/IP Properties” on page C-8 or “Verifying TCP/IP
Properties for Macintosh Computers” on page C-19 to find your computer’s IP address.
Follow the instructions in Appendix C to configure your computer.
Note: If your computer’s IP address is shown as 169.254.x.x, the computer is not configured
correctly for your network. Recent versions of Windows and MacOS will generate and assign
a 169.254.x.x IP address if the computer cannot reach a DHCP server. These auto-generated
addresses are in the range of 169.254.x.x. If your IP address is in this range, check the
connection from the computer to the router and reboot your computer.
• Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet
Explorer, click Refresh to be sure the Java applet is loaded.
• Try quitting the browser and launching it again.
• Make sure you are using the correct login information. The URL for the router is
http://www.routerlogin.net or http://www.routerlogin.com. The factory default login name is
admin and the password is password, both in lower case letters. Make sure that CAPS LOCK
is off when entering this information.
If the router does not save changes you have made in the Web Configuration Interface, check the
following:
• When entering configuration settings, be sure to click the APPLY button before moving to
another menu or tab, or your changes are lost.
• Click the Refresh or Reload button in the Web browser. The changes may have occurred, but
the Web browser may be caching the old configuration.
Troubleshooting the ISP Connection
If your router is unable to access the Internet, you should first determine whether the router is able
to obtain a WAN IP address from the ISP . Unless you have been assigned a static IP address, your
router must request an IP address from the ISP. You can determine whether the request was
successful using the Web Configuration Manager.
To check the WAN IP address:
1. Launch your browser and select an external site such as www.netgear.com
2. Access the Main Menu of the router’s configuration at http://www.routerlogin.net.
Troubleshooting Common Problems 6-3
August 2004
NETGEAR Wireless Router Setup Manual
Under the Maintenance heading, select Router Status
3.
4. Check that an IP address is shown for the WAN Port
If 0.0.0.0 is shown, your router has not obtained an IP address from your ISP.
If your router is unable to obtain an IP address from the ISP, you may need to force your cable or
DSL modem to recognize your new router by performing the following procedure:
1. Turn off power to the cable or DSL modem.
2. Turn off power to your router.
3. Wait five minutes and reapply power to the cable or DSL modem.
4. When the modem’s lights indicate that it has reacquired sync with the ISP, reapply power to
your router.
5. Then restart your computer.
If your router is still unable to obtain an IP address from the ISP, the problem may be one of the
following:
• Your ISP may require a login program.
Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of login.
• If your ISP requires a login, you may have incorrectly set the login name and password in the
router.
• Your ISP may check for your computer's host name.
Assign the computer Host Name of your ISP account as the Account Name in the Basic
Settings menu.
• Your ISP only allows one Ethernet MAC address to connect to Internet, and may check for
your computer’s MAC address. In this case:
Inform your ISP that you have bought a new network device, and ask them to use the router’s
MAC address.
OR
Configure your router to spoof your computer’s MAC address. This can be done in the Basic
Settings menu.
If your router can obtain an IP address, but your computer is unable to load any Web pages from
the Internet:
• Your computer may not recognize any DNS server addresses.
6-4 T ro ub lesh oo tin g Co mm o n Proble m s
August 2004
NETGEAR Wireless Router Setup Manual
A DNS server is a host on the Internet that translates Internet names (such as www addresses)
to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS
servers for your use. If you entered a DNS address during the router’s configuration, reboot
your computer and verify the DNS address as described in “Install or Verify Windows
Networking Components” on page C-9. Alternatively, you may configure your computer
manually with DNS addresses, as explained in your operating system documentation.
• Your computer may not have the router configured as its TCP/IP gateway.
If your computer obtains its information from the router by DHCP, reboot the computer and
verify the gateway address as described in “Install or Verify Windows Networking
Components” on page C-9.
Troubleshooting a TCP/IP Network Using a Ping Utility
Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet
to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP
network is made very easy by using the ping utility in your computer or workstation.
Testing the LAN Path to Your Router
You can ping the router from your computer to verify that the LAN path to your router is set up
correctly.
To ping the router from a running Windows 95 or later:
1. From the Windows toolbar, click on the Start button and select Run.
2. In the field provided, type Ping followed by the IP address of the router, as in this example:
ping 192.168.1.1
3. Click on OK.
You should see a message like this one:
Pinging <IP address> with 32 bytes of data
If the path is working, you see this message:
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
If the path is not working, you see this message:
Request timed out
Troubleshooting Common Problems 6-5
August 2004
NETGEAR Wireless Router Setup Manual
If the path is not functioning correctly, you could have one of the following problems:
• Wrong physical connections
— Make sure the LAN port LED is on. If the LED is off, follow the instructions in “LAN
or Internet (WAN) Port Lights Not On” on page 6-2.
— Check that the corresponding Link LEDs are on for your network interface card and
for the hub ports (if any) that are connected to your workstation and router.
• Wrong network configuration
— Verify that the Ethernet card driver software and TCP/IP software are both installed
and configured on your computer or workstation.
— Verify that the IP address for your router and your workstation are correct and that the
addresses are on the same subnet.
Testing the Path from Your Computer to a Remote Device
After verifying that the LAN path works correctly, test the path from your computer to a remote
device. From the Windows run menu, type:
PING -n 10 <IP address>
where <IP address> is the IP address of a remote device such as your ISP’s DNS server.
If the path is functioning correctly, replies as in the previous section are displayed. If you do not
receive replies:
— Check that your computer has the IP address of your router listed as the default gateway. If
the IP configuration of your computer is assigned by DHCP, this information will not be
visible in your computer’s Network Control Panel. Verify that the IP address of the router
is listed as the default gateway as described in “Install or Verify Windows Networking
Components” on page C-9.
— Check to see that the network address of your computer (the portion of the IP address
specified by the netmask) is different from the network address of the remote device.
— Check that your cable or DSL modem is connected and functioning.
— If your ISP assigned a host name to your computer, enter that host name as the Account
Name in the Basic Settings menu.

— Your ISP could be rejecting the Ethernet MAC addresses of all but one of your computers.
Many broadband ISPs restrict access by only allowing traffic from the MAC address of
your broadband modem, but some ISPs additionally restrict access to the MAC address of
a single computer connected to that modem. If this is the case, you must log in to the
router and use the Basic Settings menu to configure your router to “clone” or “spoof” the
MAC address from the authorized computer.
Restoring the Default Configuration and Password
This section explains how to restore the factory default configuration settings, changing the
router’s administration password to password. You can erase the current configuration and restore
factory defaults in two ways:
• Use the Erase function of the router (see “Erasing the Configuration” on page 5-3).
• Use the Default Reset button on the rear panel of the router. Use this method for cases when
the administration password or IP address is not known.
To restore the factory default configuration settings without knowing the administration password
or IP address, you must use the Default Reset button on the rear panel of the router.
1. Press and hold the Default Reset button until the power light blinks on (about 10 seconds).
2. Release the Default Reset button and wait for the router to reboot.
If the wireless router fails to restart or the power light continues to blink or turns solid amber,
the unit may be defective. If the error persists, you might have a hardware problem and should
contact technical support.

backwards compatible with 802.11b.
Cat 5
Category 5 unshielded twisted pair (UTP) cabling. An Ethernet network operating at 10 Mbits/second
(10BASE-T) will often tolerate low quality cables, but at 100 Mbits/second (10BASE-Tx) the cable must be
rated as Category 5, or Cat 5 or Cat V, by the Electronic Industry Association (EIA).
This rating will be printed on the cable jacket. Cat 5 cable contains eight conductors, arranged in four
twisted pairs, and terminated with an RJ45 type connector. In addition, there are restrictions on maximum
cable length for both 10 and 100 Mbits/second networks.
DHCP
An Ethernet protocol specifying how a centralized DHCP server can assign network configuration
information to multiple DHCP clients. The assigned information includes IP addresses, DNS addresses, and
gateway (router) addresses.
DNS
Short for Domain Name System (or Service), an Internet service that translates domain names into IP
addresses.
Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on
IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the
corresponding IP address. For example, the domain name www.example.com might translate to
198.105.232.4. The DNS system is, in fact, its own network. If one DNS server doesn't know how to
translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.

NETGEAR Wireless Router Setup Manual
Domain Name
A descriptive name for an address or group of addresses on the Internet. Domain names are of the form of a
registered entity name plus one of a number of predefined top level suffixes such as .com, .edu, .uk, etc. For
example, in the address mail.NETGEAR.com, mail is a server name and NETGEAR.com is the domain.
DSL
Short for digital subscriber line, but is commonly used in reference to the asymmetric version of this
technology (ADSL) that allows data to be sent over existing copper telephone lines at data rates of from 1.5
to 9 Mbps when receiving data (known as the downstream rate) and from 16 to 640 Kbps when sending data
(known as the upstream rate).
ADSL requires a special ADSL modem. ADSL is growing in popularity as more areas around the world
gain access.
Dynamic Host Configuration Protocol
DHCP. An Ethernet protocol specifying how a centralized DHCP server can assign network configuration
information to multiple DHCP clients. The assigned information includes IP addresses, DNS addresses, and
gateway (router) addresses.
Gateway
A local device, usually a router, that connects hosts on a local network to ot her networks.
IP
Internet Protocol is the main internetworking protocol used in the Internet. Used in conjunction with the
Transfer Control Protocol (TCP) to form TCP/IP.
IP Address
A four-byte number uniquely defining each host on the Internet, usually written in dotted-decimal notation
with periods separating the bytes (for example, 134.177.244.57).
Ranges of addresses are assigned by Internic, an organization formed for this purpose.

SSID
A Service Set Identification is a thirty-two character (maximum) alphanumeric key identifying a wireless
local area network. For the wireless devices in a network to communicate with each other, all devices must
be configured with the same SSID.
This is typically the configuration parameter for a wireless PC card. It corresponds to the ESSID in the
wireless Access Point and to the wireless network name. See also Wireless Network Name and ESSID.
Subnet Mask
A mask used to determine what subnet an IP address belongs to. Subnetting enables a network administrator
to further divide an IP address into two or more subnets.
An IP address has two components, the network address and the host address. For example, consider the IP
address 150.215.017.009. Assuming this is part of a Class B network, the first two numbers (150.215)
represent the Class B network address, and the second two numbers (017.009) identify a particular host on
this network.

NETGEAR Wireless Router Setup Manual
Subnetting enables the network administrator to further divide the host part of the address into two or more
subnets. In this case, a part of the host address is reserved to identify the particular subnet. This is easier to
see if we show the IP address in binary format. The full address is: 10010110.1 1010111.00010001.00001001
The Class B network part is: 10010110.11010111
and the host address is 00010001.00001001
If this network is divided into 14 subnets, however, then the first 4 bits of the host address (0001) are
reserved for identifying the subnet.
The subnet mask is the network address plus the bits reserved for identifying the subnetwork. (By
convention, the bits for the network address are all set to 1, though it would also work if the bits were set
exactly as in the network address.) In this case, therefore, the subnet mask would be
11111111.11111111.11110000.00000000. It's called a mask because it can be used to identify the subnet to
which an IP address belongs by performing a bitwise AND operation on the mask and the IP address. The
result is the subnetwork address: Subnet Mask 255.255.240.000 11111111.11111111.11110000.00000000
IP Address 150.215.017.009 10010110.11010111.00010001.00001001
Subnet Address 150.215.016.000 10010110.11010111.00010000.00000000
The subnet address, therefore, is 150.215.016.000.
