I have a DWL-G510 Rev.C
I stumbled across this link (D-link DWL G510 pci rev C [HELP] - openSUSE Forums) and I followed this;
You do not need and should not use ndiswrapper. What you need to do is
install the firmware that the driver is asking for.Go to http://www.ralinktech.com/ralink/Hom...ort/Linux.html,
download the RT2501 firmware, unzip the file and copy (as root) the
rt*.bin files to /lib/firmware. After you do that, your device should
work.Larry
But it didn’t work. What’s wrong?
Okay, an update so this makes more sense…I’ve added the outputs of the following commands;

looks like you are using ndiswrapper & got it working, just needs setting up to acces your wireless router/modem
Andy
p.s. would have also been better if you posted this in the wireless section,may have gotten quicker results 
Anyone Explain this? Usual Suspect DWLG510
