I highly recommend pfSense for home users that want some control and up to date security. Their software package has been continually updated for I believe 10 years or more and it still runs on the same hardware you could run it on in 2006. These janky systems that D-Link sell often stop getting software updates very soon after release (inside of 24 months or so).
This leaves users vulnerable and as has been shown by the FTC they ship from the very beginning with open flaws that put people at risk. Don't use this junk, turn an old PC you have (or laptop) into a router instead or buy a ready-made pfSense appliance.
