When a piece of hardware goes missing, but then comes back after a period of time with the unit off, this makes me think "thermal flakey". By that I mean, when the unit warms up, things expand, and an intermittent connection is lost because of a hairline crack or a poorly mounted device.
One of the things I would do is open the device and make sure it hasn't collected a good deal of material that may be affecting proper cooling. With the unit off, carefully use a vacuum or more ideally, a can of compressed air, and remove any buildup.
Then I would re-seat all cards. This might result in sufficient mechanical flexing to make the connection reliable again.
I think you can find a driver for the adapter and your OS here:
