Also, a ‘Realtek family controller’ or something different altogether may not be the correct adapter to have. People may have this on-board your motherboard, however a family controller is likely not the same as a NIC ethernet adapter. For anyone that has this listed in their device manager, you can always try this guide with such a family controller or what you may have on-board, but as mentioned I do not believe this particular device is the same as a NIC ethernet adapter, which allows for a true Windows waking process.
Here is a description from Quora.com that speaks of what a Family controller does-

And not to worry, if you don’t have a NIC ethernet adapter installed, there may be an easy fix for this. Below is a link that lists NIC ethernet adapter cards/and dongles available to buy online. Or you could simply head to your local computer shop and by it from them. This may be as easy as spending $20 on such a device.
In Google, simply search for keywords such as ‘Buy NIC ethernet adapter online’, and then find an adapter card or a dongle (meaning a plug and play external USB stick-like device) which looks decent and usable. And remember, you get what you pay for.
Here is Amazon US’s store on internal NIC ethernet adapter cards-

I hope this then helps anyone that may be having issues with their particular internal LAN device configuration.
