I recently added a TP-Link Archer C7 v2 w/gargoyle version 1.9.0 as a wireless ap to my existing wired network. everything is working except web monitoring.
my phone/tablet/roku all connect wireless and work, I have web usage monitor checked w/the default values, but both sites and searches are empty.
here is a settings screenshot and network map in case my setup is the problem: http://imgur.com/nIqColo
Helpful screenshots.
Gargoyle needs to operate through the WAN port for any of its useful functionality to work. Having it work as a LAN->WIFI AP doesn't fulfill these requirements.
In your network map, you should reverse the roles of the existing router and the gargoyle router.
