Problem 
Troubleshooting Suggestion 
I forgot/lost my user ID or 
password. 
If you have not changed the password from the 
default, try using “admin” as both the user ID 
and password. Otherwise, you can reset the 
device to the default configuration by pressing 
three times the Reset Default button on the 
front panel of the device. Then, type the default 
User ID and password shown above. 
WARNING:
Resetting the device removes any 
custom settings and returns all settings to their 
default values. 
I cannot access the web pages 
from my browser. 
Use the ping utility, discussed in the following 
section, to check whether the PC can 
communicate with the device’s LAN IP address 
(by default 192.168.1.1). If it cannot, check the 
Ethernet cabling. 
Verify that you are using Internet Explorer or 
Netscape Navigator v4.0 or later. 
Verify that the PC’s IP address is defined as 
being on the same subnet as the IP address 
assigned to the LAN port on the device
.
My changes to the web pages 
are not being retained. 
Be sure to use the 
Confirm Changes 
function 
after any changes. 
Diagnosing Problem using IP Utilities 
Ping 
Ping is a command you can use to check whether your PC can recognize other 
computers on your network and the Internet. A ping command sends a message to 
the computer you specify. If the computer receives the message, it sends messages 
in reply. To use it, you must know the IP address of the computer with which you are 
trying to communicate. 
On Windows-based computers, you can execute a ping command from the Start 
menu. Click the Start button, and then click Run. In the Open text box, type a 
statement such as the following: 
ping 192.168.1.1 
Click OK. You can substitute any private IP address on your LAN or a public IP 
address for an Internet site, if known. 
If the target computer receives the message, a Command Prompt window is 
displayed: 
If the target computer cannot be located, you will receive the message Request timed 
out. 
Using the ping command, you can test whether the path to the device is working 
(using the preconfigured default LAN IP address 192.168.1.1) or another address you 
assigned.
