D-Link DWL-G510 Rev C (RT61/RT2561) in Win7 x64  

bump.

I have also rev.C2.
Well I posted some kind of solution (worked for me) on Hardware Canucks. It seems to me that the DLink drivers are quite finicky. I got my drivers from the DLink UK FTP. They are version 2.1.2.0 I believe.
1. Device manager, click on the interface (driver not installed) update driver and point to the Vista64 drivers. Drivers Install correctly (or so it seems).
BUT if you leave like that, you are bound to have problems. For me downloads were throttled to 1 mbps and from a friend's experience, she was losing connection altogether until she rebooted.
2. Device manager, right-click on the wireless interface (seemingly working correctly) and then UNINSTALL .At the bottom there is a tick box saying something like 'Do you want to remove the driver files from the computer?'. DO NOT TICK THE BOX. Click Apply (or next or whatever).
3. Still in the Device manager: rescan for new hardware. It will see the interface and install the driver, but this time correctly.

Hope that helps.

I've tried that but my rate still is stuck at 3Mb/s instead of 8Mb/s with laptop. You sure you got 2.1.2 ? Thanks.

I'm sure about the driver.

The problem is, and this is driving me nuts, I can't seem to reproduce the 'successful install', i.e. full transfer speeds and so on. Now, if you are already on 2.1.2, Windows Update will give you 3.0.1 or something (it showed up as an update 2 or 3 days ago), but for me it doesn't change anything in terms of speed.
I thought it had something to do with the card being not seated properly (I had to take it out/ set it back in to access the wires of my graphics card), but last night I installed ubuntu 9.10 and I had transfer rates at least 6 or 7 times higher than on Windows!! And this with default ubuntu drivers!!! What the hell is going on?

I'm going to try again from scratch and see if I can successfully install the drivers again. Will keep you updated. Feel free to tell me if you have discovered something new.

I understand, it is very frustrating. Especially when Microsoft says that the D-Link card is officially supported by Windows 7. Now to come back to my ubuntu setup, even there the transfer rates are not stable... So is it a hardware problem?

Hello,

Dlink seems to have make an update to its installation package for the DWL-G510, I downloaded it and it includes the 3.0.1 driver from ralink and miracle, things are working fine apparently, I got a 10Mb/s test of my connection.
Now I need some time for stability evaluation.

I have just purchased & installed a G510, based on the promise of Win 7 (32) compatibility. Initially I installed the CD drivers in the box: did not work. I downloaded latest from D-link & installed: did not work. I then found this thread and downloaded the dwl-g510_C2_v5.20s0037_EU_S0038_Win7 package and installed it (using setup). Appeared to install fine, makes no difference to the problem. I deinstalled / reinstalled, then deinstalled, removed the card, reinstalled drivers & card - trying to get a complete clean reinstall. Still same problem.

Win7 diagnostic says "Windows couldn't automatically bind the IP protocol stack to the network adapter".

Driver files are:
rt61.sys - Ralink 3.00.01.0000
vwifibus.sys - MS 6.1.7600.16385
RaCoInst.sys.dll - Ralink 1.0.6.1

I know the G510 card is OK because the machine has WinXP dual boot, installed & worked first time with the original CD drivers.

Without the wireless working it has no net connectivity in Win 7 so I cannot use any auto-updates.

Any advice - please !!!

I have had loads of problems with this card in Vista 64, Win7 32 and Win7 64. But nothing like what you are experiencing. You sure it's Rev C2 you got?
