If Something Goes Wrong	179
Wireless networking problems

❖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.

NOTE To enable or disable wireless communication, use the Hot Key Fn + F8. For more information see “Hot Keys/TOSHIBA Cards” on page 190.

❖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.

❖Connect your computer directly to your router or broadband modem, by plugging a standard CAT5 Ethernet patch cable (sold separately) into your computer's RJ45 Ethernet port. If your connection problem disappears, the problem lies in the Wi-Fi®part of your network.
