Hello and welcome to the forums.
Are you sure you have the same problem. The OP was running a release candidate of Windows 7. Hopefully you're running a more current version.
Open device manager, expand network adapter, right click the problem adapter and choose properties, select the details tab, select the drop down in the property frame and choose "Hardware Ids"
In the value box right click and choose select all, right click again and choose copy. Paste them into your next post and someone may be able to help with a driver.
Keep us posted.
