Spent hours on this problem. I have the F5D7000 v3 and none of the 'install drivers in compatibility mode' solutions worked.
This card actually uses the Ralink RT2500 chipset, and Ralink provide Windows 7 drivers for this chipset (both 32- and 64-bit).
Go to their site (www.ralinktech.com) and click on the Software section. Download the drivers for PCI/mPCI/CB (RT2500) and install them. When I did this the link was verrry slow (8Kb/s), but be patient and it will get there.
Once the drivers are installed, go into Device Manager and select the card. Click 'update driver' and select from a list of devices. There will now be a section called "Ralink Inc." or something. In there there will be an option for the RT2500 card. Select this and it installs and runs perfectly.
Hope this helps someone.
