Wireless puzzler...NIC will send, *not* receive

I have a homebrew PC with a DLink DWL-G510 wireless NIC. This PC
suffered from an OS corruption problem earlier this week, and I'm in
the final stages of getting it back on it's feet - a WinXP Pro box
w/SP2.

With the OS now back on its feet and happy, I'm down to the last step -
getting this blasted NIC working.

The problem is that with a good signal and an apparent connection
message from the card's management utility, it will not receive
*anything* from the network. I have used the manufacturer's
configuration utility AND MS WZC to configure the WEP encryption key
multiple times to no avail (and this key works properly for the other
wireless clients using this network). The network shows up in the card
utility's site survey app on the proper channel with encryption turned
on, but so far it will send, but still not receive.

I've verified that the Windows Firewall is turned off; the machine has
no antivirus or other programs (it's used primarily as a DVR), it can
ping itself, and the routing table is correct (proper outbound routes,
etc). But nothing ever comes back; pings time out (names are never
resolved and hard IP addy's just time out), tracerts never make it to
the gateway, names never get resolved by my DNS server, so something is
obviously still wrong.

I've uninstalled and reinstalled the card drivers, verified that my
external firewall isn't (via some sort of weird misconfiguration)
seeing and dumping packets from this box, and verified that it is
getting the proper IP address -- and all is as it should be.

I'm beginning to wonder if the antenna itself is physically broken; but
it would seem that idea is less likely given that it tells me it has
established a connection. Given that all other wireless clients in this
network are functioning perfectly, and I've checked what I know to
check several times, I'm afraid I'm at the head-scratching point. I'd
love to find out it was something stupid I've just overlooked.

If anyone has any suggestions, I'd be most appreciative.

Thanks

It *tries* to send, like talking out loud when you're alone.

Try it with encryption turned off temporarily.

p.s. Strongly advise using WPA instead of WEP, which is easily cracked.

John,

Thanks for the tip.

I originally tried to configure all my wireless clients to use WPA, but
the version of the firmware for my router that supported WPA is buggy
and never worked correctly. I was more or less forced back to WEP. I
certainly appreciate the relative "hackability" of it, but given that
there are a minimum of five other wide-open networks in the area that
show up on my laptop's site-survey, I suspect those provide an open
door where mine at least has a chain-lock...

Thanks again,

WEP has been demonstrated to be able to be cracked, at 64 bit, within 3
minutes by a US Govt agency not all that many years ago.

Is DNS forwarding turned on in the router? Try entering the router IP as DNS
server in your wireless adapter configs. Alternatively you can use your ISPs
DNS server address(es). Set gateway IP to match.

Thanks for your input.

The router is really only being used as an access point and isn't used
to go to the Internet. Outbound Internet access is handled through a
separate, dedicated box that serves as the gateway for all clients
(wired or not). This particular wireless client can't even ping that
box (or any other machine on the local network) either via hostname or
hard-IP address. I have no doubt the outbound packets are being sent,
but no data ever comes back. As far as the box is concerned, the
requests simply time out pending data that never arrives.

The network address, mask, and gateway are manually defined and have
been triple-checked and verified to be correct. The routing tables also
confirm that there is a correct route available to the other machines
on the network (subnet).

At this point, I have all but concluded the card to have some type of
hardware fault, and have rigged up a conventional hardwire connection
to my local network, and that worked immediately. In that vein, I've
overcome the problem, but I'd still like to know precisely what's wrong
with the wireless card...or what I've done incorrectly (which is
obviously more likely).

Thanks for your input anyway,

Intrepid
