Wireless networking problems

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 Start, Control Panel, System 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.
To enable or disable wireless communication, use the Hot Key
Fn+F8. For more information see “Hot Keys/TOSHIBA Cards” on
page 200.
❖ 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 ® .
1 Click Start to open the Start menu.
2 Type Cmd in the Search programs and files field.
3 Enter IPCONFIG /ALL and press Enter.
The IP address for each active network adapter will be
displayed.
