This section provides information on troubleshooting problems with your IBM
High Rate Wireless LAN Gateway.
v Power LED is off
If the power LEDs are off while the Gateway is turned on, be sure that the
power adapter is properly connected to your Gateway. Be sure that you are
using the 12V dc power adapter included in your option package. If the
problem persists, contact the IBM HelpCenter.
v Self-test LED stays on for more than 30 seconds
If you experience problems with the Self-test LED, cycle the power to see if
the Gateway recovers and the LED stays on for a short amount of time. If
the error persists, contact the IBM HelpCenter.
v Check your LAN connections to the Gateway.
After checking the Ethernet connection between your computer and the
server, use the TCP/IP PING command to determine of the TCP/IP settings

1. If you are using a Windows-based computer, click Start → Programs →
Accessories → Command Prompt.
2. Type PING 192.168.1.1.
Note: If you have changed the IP address of the Gateway, type the new
IP address after PING.
If you receive replies for this command, the IP address of your computer
is set up correctly.
If you do not receive replies for this command, check that you typed the
correct IP address. If the problem persists, contact the IBM HelpCenter.

After verifying that the LAN path works correctly, test the path from your
computer to a remote device:
1. Connect your Gateway to the Internet with a DSL/Cable modem.
2. If you are using a Windows-based computer, click Start → Programs →
Accessories → Command Prompt.
3. Type PING 192.168.1.1, followed by the IP address of a remote device
such as the DNS server of your ISP.
