Wireless LAN problems

Okay, I'll try to explain everything the best way I can, ask if anything is unclear...

There's 2 computers connected to a wireless router. The issue is the connection between 1 of the computers and the router. The router is a D-Link DI-514 with upgraded firmware (v1.02) and the network card is a D-Link DWL-G520+ (firmware 1.0.11).

Geography: Computer #1 3 meters from the router, nothing but a fridge blocking a straight connection. Computer # 2 3 meters as well but one floor up so signal has to get through 50cm of concrete floor.

The router is tested through cable connection and there is no problem with it as far as cable connection can tell. The network card is replaced by D-Link since we thought that was the problem but no, same thing happens with both old and new card.

What happens is that when you boot up there are no connection with the network. The control program starts with Win and everything should be a go but it isn't. There are no obvious interfearance such as Win's own 'configure network settings' or such. Everything is made by the book, still no connection. It's first when you fiddle around with the antenna in the network card that you actually get connected, and when finally connected you get really high signal strength. It's either 'very high' or 'excellent'. So it looks like the antenna is damaged except I don't belive 2 seperate cards can act the same, especially since this card is brand new. It also sits perfectly in a never-been-used PCI slot. The drivers were installed before the card as well. When trying the card in the other computer you wind up with the exact same problem (so far).

Furthermore; When you finally get a connection you get an IP, subnet mask and gateway address as you're suppose to, but when trying to ping or access the router in any way all you get is timeouts. You won't get passed the router. It looks like there's a firewall interfearing, blocking you out of the network. Except, there are no firewalls enabled. The router is resetted over and over again, and the computer is carefully sweaped for hidden firewall software. Windows own is not enabled. This happens only on computer #1, not on the second.

So my problem is a bad or corrupted connection to the router and when I finally connect I get blocked out. Two separate problem it seems.

What do I try next?

Try swapping the cards out in the machines.

 

Couldn't swap cards since the second computer used a wireless lan usb adapter, wierd thing is that worked great


Anyway, after much consideration and a lotta scratching the head I decided to try something really stupid. So I swapped routers with my own. And OMG! It worked. So I've contacted D-Link and they're sending my a replacement. Christ... didn't think the router could do such circus acts but hell, I was wrong

Thanks for your effort!
