I have an Asus F3s notebook with Vista Home Premium installed.  It works perfectly with the onboard wireless network adapter.  I have installed a DWA-643 and the computer will not sleep, hibernate or shut down with the DWA-643 enabled.

Windows update has updated the driver from version 7.3.1.42 which was the version downloaded from the Dlink website and used in the installation to version 7.3.1.127 but this has made no difference.

In device manager I have set up the DWA-643 to not be able to wake the computer.  There are no wake on LAN, modem or PCI device options in the BIOS (AMI BIOS v.207).

I have read reports of others having the same problem so I hope there is a known fix!

In the advanced options for the card, in device manager, are there any options for power saving features? Just a thought.

There is an option to allow the computer to turn off the device to save power.  I have tried with this enabled and disabled, it makes no difference.

Well I returned the DWA-643 as the problem has not been fixed despite trying all sorts of things which Dlink support suggested.  It will be interesting to see if this sort of problem crops up again - I have certainly seen references to it elsewhere.

I did some rudimentary comparisons of file transfer times using the DWA-643 and the Intel 3945ABG which came installed in the computer.  When in close proximity to the DIR-655 router the transfer speed of the DWA-643 was noticeably quicker, over twice as quick.

At distance however, the 3945ABG was much quicker.  I put this down to the antenna attached to the 3945ABG being much better (runs around the screen) than that of the DWA-643.  There was certainly no point battling on with the DWA-643 for better range.  This was an issue I had not considered prior to purchase, I had expected improved range.

Good for you that you returned it.  Got the same problem with the DWA-643, my HP notebook won't shutdown.  It will just restart.  Tried everything  as DLINK suggested but no avail. In the end, the are blaming my laptop to be the issue.  So much for DLINK support, so disappointing.

I have the same problem.  I have 2 sony vaio laptops and a bunch of these cards all not able to shutdown.  I am using windows 7 ultimate 64.  If any solutions please post in this thread.
Thanks

Hi all I just got this little card and love it but I too had this problem and I played around and finally fixed it.
First you need to completely remove the DLINK program so in Vista go into control panel->programs and features look for the DWA-643 program and unistall it, leave the card in while you do this. After this is done go to control panel->device manager->network adapters and uninstall the DWA 643 you will be prompted if you want to remove all drivers check the radio box and say ok or yes sorry forgot what is was. Now after that's all done pull out the DWA 643 and restart your laptop.  Now I downloaded the latest drivers from DLINK and unzipped them to a location I knew, you will need to know where they are so put them somewhere easy to find. I used desktop its easy to find.  Now once your system back to desktop put the DWA 643 back in wait for windows to say it failed to install the device then go control panel->device manager you will see an unknown network controller listed. That is the DWA 643 right click on it and pick update drivers.  You will get a pop up pick browse my computer for drivers now here is where you need to remember where you put the drivers.  Click on browse, now navigate to the folder for the DWA 643 and open up the drivers folder then pick your OS only 2 there, xp of vista. Now install the drivers. You card will work and you will be able to get your laptop to sleep. Now be warned do not use the DLINK provided Network manager that is what is preventing our systems from staying in sleep mode.  I hope this helps good luck.
