If Something Goes Wrong Wireless networking problems 137 ❖ 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, from the Start screen begin typing Computer, or if you are in the Desktop screen, move your pointer over the upper or lower right corner of the screen. When the Windows® Charms appear click the Search ( ) Charm, and then type Computer. Click 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 F12 key. For more information see "TOSHIBA Function Keys" on page 146. ❖ 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 From the Start screen, type Cmd. 2 Click Command Prompt. 3 Enter IPCONFIG/ALL, and then 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. ❖ If you have enabled any security provisions (closed system, MAC address filtering, Wired Equivalent Privacy [WEP], etc.), check the access point vendor's Web site for recent firmware upgrades. Problems with WEP keys, in particular, are frequently addressed in new firmware releases. The Windows® operating system wireless management utility does not work. If you are using an external Wi-Fi® adapter (USB adapter or other variety), check if the adapter comes with its own management utility. If it does, the utility may be disabling the Windows® operating system wireless management utility, in which case you must use the adapter's management utility. If the documentation that accompanies the adapter does not provide enough information
