Intel PRO Wireless 3945ABG (Latitude D620) and 2WIRE 1000SW

Question

Although a connection can be established with my 2WiRE modem/router 1000sw from my Dell D620 (Windowx XP Service Pack 2) built-in wireless network adapter Intel PRO Wireless 3945ABG, it doesn't allow accessing network through TCP/IP. DHCP is enabled and IP address and DNS are obtained automatically. Connections through Ethernet and D-Link DWL 650+ PC Card with the 2Wire 1000sw successfully allow network access through TCP/IP. Ping to the gateway server through IP address is occasionally successful from Intel PRO Wireless 3945ABG, whereas it is always successful from Ethernet and D-Link DWL 650+ PC Card. Updated the driver for Intel PRO Wireless 3945ABG to the latest version 10.5.1.75, but no luck. Tried connections from Windows Wireless Zero Configuration and Intel PRO Set/Wireless, but no luck. Found this Intel 3945ABG known issue:http://support.intel.com/support/wireless/wlan/sb/cs-006205.htm A solution provided does not work as there are no new 2Wire 1000sw software or firmware is available. Tried a temporary workaround to manually set the wireless adapter to CAM (continually aware mode), which disables the PSP (Power Save Polling) capability, but no luck. Questions:1. Am I facing the issue described in the Intel known above ?2. If so, how can I fix it ?3. If not, what is causing the issue and how can I fix it ?

Sent an email to Dell Support and got a response instructing me to call them. Gave a call and a technician connected my PC through Dell Connect and checked the configuration. He eventually downloaded and installed the Intel driver from Dell support web site (rather than from Intel), 10.5.1.72, which is lower than the one I have downloaded and installed from Intel. After the reboot, tried the TCP/IP connection, but no luck.   Called Dell Support again. Another technician connected to my PC through Dell Connect and took a look. He tried several things, e.g. starting up the system with Safe mode and re-installing 10.5.1.72 driver. But no luck. At the end, he transferred me to 'Dell on Call' department specializing in 3rd party configurations. Then I was told to pay $129.00 for one time service or $236.00 for 1 year service. No way I am paying this.   Any help is appreciated.

Can you please post the results of ipconfig /all? You might also try to rebuild the TCP/IP stack and winsock here is a knowledge base article on how to do this.
