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 is ON.
❖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.
❖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, press F12. For more
information see “Hot Keys/TOSHIBA Cards” on page131.
❖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®.
