Performance :: Slow Internet Reconnect After Wakes From Sleep

My new Asus Win10 machine with a solid-state hard drive wakes up from sleep refreshingly quickly -- just a couple of seconds. But it takes between 15 and 40 seconds before the Internet connection is re-established. Once the connection is re-established, it works fine. But that delay is annoying. Can I do something to speed up the re-connection?

I don't know where the delay is coming from. My NIC is plugged directly into my Comcast cable modem -- no other routers or the like involved. The NIC on the machine claims to be an "Intel Ethernet Connection (2) 1219-V", running driver version 12.13.17.4, which is claimed to be the current version. The "Power Management" tab in Device Manager for the NIC lists three power-saver options, all of which are enabled (that is, the boxes are checked):

Respond to ARP requests without waking system
Respond to NS requests without waking system
Energy Efficient Ethernet

(I am attaching a PNG of the Power Management tab.) These options suggest that the NIC should be able to keep the Internet connection alive, even during sleep. So I don't know why I am experiencing a delay in re-establishing the connection.
