A number of ways you can find drivers:
1. Run windows update. It should find most missing drivers. They may show up under optional updates.
2. You haven't listed your computer specs so I can give only a generic answer, but most manufacturers have installed apps to keep drivers updated. eg:Lenovo Vantage, Dell Command Update, etc)
If you have an Intel machine Intel Driver and Support assist tool can also help.
3. Go directly to your manufacturers site.
4. Right click on device and select update driver.
5. Research drivers by device id. Right click on device in device manager, select properties. Select Details tab. It may give you a name in descriptive value. Under 'Property' click down arrow and select Hardware Ids. You can take the value you find there and do a web search. Personally I use
PCI Lookup
The first four digits in device id is the vendor, the last 4 digits is the device.
From what you show is missing I would suspect it is related to chipset.
