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

❖

If your computer is equipped with an internal Wi-Fi

®

 adapter, 

verify that the Wireless antenna is ON (the wireless indicator 
light 

 will be lit).

❖

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.

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. 

❖

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. To access 
the Device Manager, click the Start button, and then in the 
Search field, type System. In the list that appears above, click 
your selection. Carefully note any error messages 

-
