Troubleshooting
This chapter provides information about troubleshooting your NETGEAR WG102 ProSafe 
802.11g Wireless Access Point. After each problem description, instructions are given to help you 
diagnose and solve the problem. For the common problems listed, go to the section indicated.
• Is the WG102 Access Point on?
• Have I connected the wireless access point correctly?
Go to “Installing the WG102 Access Point” on page 1-4.
• I cannot remember the wireless access point’s configuration password.
Go to “Changing the Administrator Password” on page 3-8.
If you have trouble setting up your WG102, check the tips below.
No Lights Are Lit on the Access Point
It takes a few seconds for the power indicator to light up. Wait a minute and check the power light 
status on the access point.
If the access point has no power.
• Make sure the power cord is connected to the access point.
• Make sure the power adapter is connected to a functioning power outlet. If it is in a power 
strip, make sure the power strip is turned on. If it is plugged directly into the wall, verify that it 
is not a switched outlet.
• Make sure you are using the correct NETGEAR power adapter supplied with your access 
point.
Wireless LAN Activity Light Is Off
The access point’s antennae are not working.

• If the Wireless LAN activity light stays off, disconnect the adapter from its power source and 
then plug it in again. 
• Make sure the antennas are tightly connected to the WG102. 
• Contact NETGEAR technical support if the Wireless LAN activity light remains off.
LAN Light is Off
There is a hardware connection problem. Check these items:
• Make sure the cable connectors are securely plugged in at the access point and the network 
device (hub, switch, or router). A switch, hub, or router must be installed between the access 
point and the Ethernet LAN or broadband modem.
• Make sure the connected device is turned on.
• Be sure the correct cable is used. Use a standard Category 5 Ethernet patch cable. If the 
network device has Auto Uplink™ (MDI/MDIX) ports, you can use either a crossover cable or 
a normal patch cable.
Cannot Access the Internet or the LAN with a Wireless 
Capable Computer 
There is a configuration problem. Check these items:
• You may not have restarted the computer with the wireless adapter to have TCP/IP changes 
take effect. Restart the computer.
• The computer with the wireless adapter may not have the correct TCP/IP settings to 
communicate with the network. Restart the computer and check that TCP/IP is set up properly 
for that network. The usual setting for Windows the Network Properties is set to “Obtain an IP 
address automatically.”
• The access point’s default values may not work with your network. Check the access point 
default configuration against the configuration of other devices in your network.
Cannot Connect to the WG102 Access Point

• The WG102 Access Point is properly installed, LAN connections are OK, and it is powered 
on. Check that the LAN port LED is on (amber indicating a 10 Mbps Ethernet connection or 
green indicating a 100 Mbps Ethernet connection) to verify that the Ethernet connection is 
OK. 
• The default configuration of the WG102 is for a static IP address of 192.168.0.229 and a Mask 
of 255.255.255.0 with DHCP disabled. Make sure your network configuration settings are 
correct.
• If you are using the NetBIOS name of the WG102 to connect, ensure that your computer and 
the WG102 are on the same network segment or that there is a WINS server on your network. 
• If your computer is set to “Obtain an IP Address automatically” (DHCP client), restart it.
• If your computer uses a Fixed (Static) IP address, ensure that it is using an IP Address in the 
range of the WG102. The WG102 default IP Address is 192.168.0.229 and the default Subnet 
Mask is 255.255.255.0. 
When I Enter a URL or IP Address I Get a Timeout Error
A number of things could be causing this. Try the following troubleshooting steps.
• Check whether other PCs work. If they do, ensure that your PCs TCP/IP settings are correct. If 
using a Fixed (Static) IP Address, check the Subnet Mask, Default Gateway, DNS, and IP 
Addresses.
• If the PCs are configured correctly, but still not working, ensure that the WG102 is connected 
and turned on. Connect to it and check its settings. If you cannot connect to it, check the LAN 
and power connections.
• If the WG102 Access Point is configured correctly, check your Internet connection (DSL/
Cable modem etc.) to make sure that it is working correctly.
•Try again.
Using the Reset Button to Restore Factory Default Settings
The Reset button (see “Rear Panel” on page 1-3) has two functions:
•Reboot. When pressed and released quickly, the WG102 will reboot (restart).
•Reset to Factory Defaults. This button can also be used to clear ALL data and restore ALL 
settings to the factory default values.

To clear all data and restore the factory default values:
1. Power off the WG102 Access Point and power it back on.
2. Use something with a small point, such as a pen, to press the Reset button in and hold it in for 
at least 5 seconds.
3. Release the Reset button. 
The factory default configuration has now been restored (see “Factory Default Settings” in 
Appendix A), and the WG102 Access Point is ready for use.
