Could you please expand the Network Adapter part in the Device Manager and resend. From the screenshot that you have sent everything seems to be fine.
Please run "Services.msc" and check the state of network services. A screenshot from my Desktop is below.
If any of the services are not running you should restart them.
In case the Services are in order and if you have the concerned Drivers
handy, you may try and uninstall the current drivers and then reinstall them.
