It's late now, and I'm getting tired, but I'll try and do some additional debugging over the weekend.
Regarding Ubiquiti... I had wanted to upgrade my WiFi for a while, because although I like the two Apple Airport Extremes that I had, I was having some odd behaviour switching between access points as I moved through the house, and neither of them supported 11ac. This need is what switched me on to Ubiquiti, because I'd heard their WiFi stuff was good.
To be honest, I also REALLY like learning new things, and had wanted to dabble with VLAN for a while, so an EdgeRouter Lite and at lease one UAP-AC-PRO were ordered, along with an Engenius POE switch (to power the AP), and a couple of Netgear low cost managed switch for other parts of my house.
It took quite a bit of time to set it all up, though simply replacing the AirPort Extreme Router functionality was very quick indeed, the firewall, VLAN and IPv6 stuff took a bit longer. Having said that though, maybe I'm crazy but I found it so much fun, and now that it's all done, I'm itching to do something similar and am looking doing an IP camera setup around our housing community!
In summary, the Ubiquiti stuff has been great. A single UAP-AC-PRO has replaced two Airport Extremes and I get better coverage throughout my (3-floor town) house, and the EdgeRouter feels faster than the AirPort Extreme whilst providing me with greater functionality. I'd say go for it, but maybe get the EdgeRouter POE rather than the EdgeRouter Lite.
