i think it is the dlink dwl g520

[kinglingping]

Hello
I just installed a DWL G520 (H/W Ver:B3 and F/W Ver:4.20) into my computer after swapping out my old DWL G510. My wireless signal (AP) is a DI 624 (Ver:C and F/W:2.53) and then is repeated by a DWL G800AP(F/W 1.04). I can no longer connect to the network and signal strength is only one bar (ie weak). It has nothing to do with the firewalls on the computers including the windows firewall because even with them all disable it doesn’t work. I swapped out my DWL G510 because it stop working complete last week, wouldn't detect a network at all. Hope you guys can help me out.
Thanks KlP

cnet review for g510

gone through 2 cards both would not be recognized , were tried on 4 different system/chipsets/OS and not once would the systems recognize the card.​

and znet review for G520 may be useful.

Znet also notes

it's compatible only with Windows. If you don't mind its laborious installation, the DWL-G520 is a solid wireless solution for your PC. Otherwise, we suggest an easier-to-install USB wireless adapter.​
