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.

❖

Use the PING command to verify a connection to the gateway 
at 192.168.1.1 (a default gateway for most wireless routers).

Click Start to open the Start menu.

Type 

Cmd

PING 192.168.1.1

 at the command prompt, and press

If “Request Timed Out” or another error message appears in

-related.

❖

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 (a PC Card, 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.

You can never predict when your computer will lock, forcing you to 
close a program and lose unsaved changes. Many software 
programs build in an automatic backup, but you should not rely 
solely on this feature. Save your work! See 

 for instructions.
