Unable to access internet using wireless card Intel 3945abg

* 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.

Everything looks correct except the weird DNS ip address which I have
no idea where is coming from.

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.

How did you manage to get a DHCP lease that only lasts 30 seconds?

Same, but only 10 seconds.

Your IP addresses also make no sense. They should be in
192.168.1.xxx, not routeable IP's. Someting is screwy with your
router.

It's past midnight and I'm too lazy to work out the possible culprits.
My guess(tm) is that your DLink DSL-2640b has gone insane. Reset,
rehash, rebuild, reload, reflash, reconfigure, or if all else fails,
recycle the router.

Incidentally, since you appear to be obtaining routeable IP addresses
via DHCP from your router, you probably have the router section
disabled and are running it in some kind of access point mode (i.e. no
router).

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?

I know my IP doesn't make sense. 3rd level support concluded that my
router was faulty.
I replaced the router and am having the exact same problem.
I'm going to troubleshoot it again - my neighbor has two laptops and
I'm going to look into it more carefully.

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.

If you have NAT disabled it explains why you are getting an IP address
of 76.237.8.247 on what should be your LAN.
Enable NAT and try again.

Just to verify, the NAT has to be enabled on the *router*, correct?
Are there any configuration parameters which might need to be set on
the network interface on my laptop?

Just enable NAT on the 2640b and as long as you are running a DHCP
server you should not need to change the settings on your laptops i/face.

Ok. I'll do this once I get home. I think I already tried and there is
actually a checkbox for that when setting up the PPPoE connection but
it is always disabled. I'll try looking around for it and will return
some feedback. Also, a neighbor of mine may stop by with two laptops
and I'll troubleshoot things further.

I called D-Link support and got disconnected three times.
The person I spoke with told me that there is no way to disable the
firewall and that the NAT service is there by default if using PPPoE.
Sounds kinda weird to me, especially the firewall is always on part.
Anyways....... I have wasted enough time on this and will probably buy
the router/modem supported by AT&T.
I guess my curiosity on this matter will never be satisfied.

I'd just like to point out that very few of the D-Link support people
were actually helpful in some way or knowledgeable.
Overall, the support was quite bad. Long wait times, lots of
disconnects, and lots of blaming the ISP or "your modem is
malfunctioning".
I don't know if the problem is a combination of the router/ISP/network
card/OS, but I have wasted enough time on it.

Thanks guys for trying to help me out.
