Re: 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
intrepid


Try this: open TCP/IP properties of the wireless connection, Advanced button, Options tab, TCP/IP Filtering properties. Verify that Filtering is not enabled, and if enabled, set all ports/protocols to Permit All and not Permit None.
