Can't connect to Wireless Network

[pvb]

I recently had to reinstall XP on my desktop and have not been able to reconnect wirelessly. Message is "Windows is unable to connect to selected network...." I have spent hours on the phone with ATT wireless support, but have had no success. The computer has an functioning ethernet connection, and locates my local wireless connection point, but will not connect. Other computers are able to make the connection, and the settings appear to be similar. My guess is something is blocking the connection, but I don't know what.

The details: Running XP with a Westell 327W router and a Linksys WUSB300N wireless device. On the router, the network is named, wireless operation is enabled, the security is WEP-64 bit, and Key 1 is filled with a 10 digit number. This is the connection point that the computer finds, but will not connect to - even though other computers find the same site, and will connect. Firewall and password status on the modem is all marked "none".

When I run "full diagnostics", all tests pass except "IP" and the message says "Cannot access ping. fastaccess.com...." ATT techs indicate this is not a problem, so not to worry about it. I can find no other error messages.

We run Windows firewall and AVG anti-virus (as we do on the other computers which do connect), but turning both off seems to make no difference. I have turned off modems, computers, rebooted numerous times, but no joy! Any suggestions?

Thanks in advance.

several things to check would be... on your router, is there a limited number of dhcp addresses available - and are the leases set to "forever", if so - increase the number of addresses in the address pool. second, check to make sure that your mac address is allowed on your router.

Try these simple tests.

Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:

NOTE: For the items below in red surrounded with < >, see comments below for the actual information content, they are value substitutions from the previous command output!

IPCONFIG /ALL

PING <computer_IP_address>

PING <default_gateway_address>

PING <dns_servers>

PING 206.190.60.37

PING yahoo.com

Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
Paste the results in a message here.

<computer_IP_address> - The IP Address of your computer, obtained from the IPCONFIG command above.

<default_gateway_address> - The IP address of the Default Gateway, obtained from the IPCONFIG command above.

<dns_servers> - The IP address of the first (or only) address for DNS Servers, obtained from the IPCONFIG command above.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.
