Trouble Connecting to the Internet via Wireless

[James R. DeLoach]

I have a problem connecting to the Internet via wireless from my
desktop computer. I can connect to my wireless network and the
Internet on another desktop computer on my network. Both computers
are running Windows XP Pro SP2. On the computer with the problem,
according to the icon on the task bar, it has a connection
to my wireless network but cannot access the Internet.
My latest endeavor involves using a Linksys wireless-G
USB network adapter. I have tried two other Linksys PCI adapters
but no luck. I even tried a D-Link wireless adapter which
worked for about two days then quit. Using wired network adapters
I can connect with no problems. Short of completely re-installing
Windows XP Pro, does anyone have any idea what the
problem could be using wireless adapters and how to troubleshoot it.
Thanks.

Regards,

James

Are you specifying the right encryption settings (64-bit WEP, 128-bit
WEP, WPA-PSK, etc) for the wireless network connection on XP Pro SP2?

What are the wireless network connection's TCP/IP settings? To see,
right-click the wireless network connection and click Status | Support
| Details. What does it show for IP address, subnet mask, default
gateway, and DNS server? How do those values compare to the values
that the wired network connection gets?

If the TCP/IP settings seem right, type these lines in a command
prompt (Start | Run | cmd) windows. Each one should get four replies:

ping <this computer's wireless network IP address>
ping <default gateway IP address>
ping 216.239.57.99
ping www.google.com
