From: jonathanztaub on 2 Feb 2008 00:47 * I have Windows XP SP2 * D-Link wireless router with built in modem dsl-2640b * Sony Vaio with Intel 3945abg wireless card * I'm relatively computer savvy * AT&T is my ISP provider I can access the internet when hard wired to the router.

This network card is able to connect to other wireless routers. The router is not defective as I have replaced it and am still experiencing the same problem. Any attempt to override the automatic settings on the router or wireless card do not result in any success even if settings are identical to wired access which is working. I have disabled all possible firewalls and anti-virus programs as well as upgrading to the latest driver updates and trying to fix my winsock. I tried connecting two other laptops but no success (both of which happened to be Sony Vaio). I can access the router wirelessly but cannot access the internet nor ping any ip address including DNS with a success (aside from the router). I have a feeling that this is a hardware issue with my wireless network card which for some reason doesn't like the router. I've posted in other places though with more emphasis on the router rather than the wireless network card. I have been trying to troubleshoot this for many days now and am at the point of giving up and getting a different router/modem, though my curiosity currently keeps me at it. If anybody else experienced something like that, I'd appreciate any pointers.

What happens to the Config if you turn off the DHCP server in the 2640b? Are you positive that NAT is enabled in the 2640b?

When I set up the internet connection, this option is disabled. I was wondering about what NAT exactly is and whether it has something to do with it. Can you explain a bit more? I'm on my way to work and can't look into it now. Thanks.

Enable NAT and try again.
