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 192.168.1.254 

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: 

 

Figure 11: 

Using the ping Utility 

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 Wireless Gateway is working (using the 

preconfigured default LAN IP address 192.168.1.254) or another address you assigned. 
You can also test whether access to the Internet is working by typing an external address, such as that for 

www.yahoo.com

 (216.115.108.243). If you do not know the IP address of a particular Internet location, you 

can use the 

nslookup

 command, as explained in the following section. 

From most other IP-enabled operating systems, you can execute the same command at a command 

prompt or through a system administration utility. 
 

nslookup 

You can use the nslookup command to determine the IP address associated with an Internet site name. 

You specify the common name, and the nslookup command looks up the name in on your DNS server 

(usually located with your ISP). If that name is not an entry in your ISP’s DNS table, the request is then 

referred to another higher-level server, and so on, until the entry is found. The server then returns the 

associated IP address. 
On Windows-based computers, you can execute the nslookup command from the 

Start

 menu. Click the 

Start

 button, and then click 

Run

. In the 

Open

 text box, type the following: 

nslookup 

Click 

OK

. A Command Prompt window displays with a bracket prompt (>). At the prompt, type the name of 

the Internet address that you are interested in, such as 

www.microsoft.com

. 

The window will display the associate IP address, if known, as shown below:
