If "Request Timed Out" or another error message
appears in response, then the problem is probably
Wi-Fi-related.
❖
If you have enabled any security provisions (closed
system, MAC address filtering, Wired Equivalent Privacy
(WEP), etc.), check the access point vendor's website for
recent firmware upgrades. Problems with WEP keys, in
particular, are frequently addressed in new firmware
releases.
Special considerations for Windows XP
Wired Equivalent Privacy (WEP) encryption is not
enabled on the wireless access point.
When you install a wireless access point device, Windows XP
checks if WEP encryption is enabled on the device. If it is not
enabled, Windows XP adds the device to its list of available
wireless networks, but does not create a wireless connection
using the device, since the connection would not be secure.
You can still, however, use the access point. To use an access
point without WEP encryption, follow these steps:
❖
Right-click the Wireless Network icon in the System
Tray (far-right portion of the Windows Taskbar).
❖
Click View Available Wireless Networks.
❖
Select Allow me to connect to the selected wireless
network, even though it is not secure.
