Wireless networking problems
Wireless networking problems
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.
If your computer is equipped with an internal Wi-Fi
®
 adapter, 
verify that the Wireless antenna ON/OFF switch 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.
To determine if your computer has an internal Wi-Fi
®
 adapter, check 
the device list in Device Manager (part of the Windows
®
 Control 
Panel, System and Security). Some Toshiba models may have a 
Wireless antenna ON/OFF switch even though they do not have an 
internal Wi-Fi
®
 adapter.
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.
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 StartControl PanelSystem and 
Security
, and then System. Carefully note any error 
messages—these will be very helpful if you should confer with 
a support technician at a later time.
