I'd try this:
1. Right click it and delete the device AND the driver. Do this until you get a generic driver. Might take several iterations.
2. Does it work?
3. Yes--Use it.
4. No--Try the Intel driver I linked.
Approach two:
Open Intel's Driver Update Utility and let it scan. See what it finds and try that driver. Note: it might tell you that you have an OEM-specific install and it won't let you update the driver from there. Then, back to the steps above.
