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 the Start button, 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 

F12

.

❖

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 the Start button 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.
