This section provides general troubleshooting tips for networking 
problems, specifically wireless (Wi-Fi

®

) networking.

The terms and concepts used assume a basic understanding of 
networks, and may be for more advanced users. If you need 
assistance or if you are not familiar with the terminology, please see 
Windows

®

 Help and Support or contact your computer technician.

❖

Verify that your computer can detect access points or routers. If 
it can detect a Wi-Fi

®

 access point or router then it may be a 

configuration issue.

❖

Verify that signal strength is good using the utility provided 
with the Wi-Fi

®

 adapter.

❖

If another computer is on the same network, verify that it has 
network access, and can connect to the Internet. If, for 
example, the other computer cannot browse to a public Web 
site, the ISP’s (Internet Service Provider) service may be 
disrupted.

❖

Verify that the Service Set Identifier (SSID), or network 
name, is correct—i.e., that it matches the SSID assigned to the 
access point you are attempting to connect through. SSIDs are 
case-sensitive. 

❖

Under System and Security click System and then check the 
Windows Control Panel's Device Manager to verify that the 
Wi-Fi

®

 adapter is recognized by the Windows

®

 operating 

system, and that the driver is loaded. Carefully note any error 
messages—these will be very helpful if you should confer with 
a support technician at a later time.

To enable or disable wireless communication, use the Hot Key 

Fn+F8

. For more information see 

❖

Use IPCONFIG to verify that the computer has a useful IP 
address—one other than the private address of 
169.254.xxx.xxx assigned by Windows

®

.

Click Start to open the Start menu.

Cmd

 in the Search programs and files field.
