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.
