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 

❖

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

®

.

Click Start to open the Start menu.

Type 

Cmd

 in the Search programs and files field.

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.

❖

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.

If you are using an external Wi-Fi

®

 adapter (an ExpressCard

®

, 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 to determine if this is the case, contact that 
vendor's support group for further advice.
