FWIW, Xfinity provided me an "xFi" modem/router combo that performed great. I replaced it with a standalone modem + a Unifi Dream Machine from Ubiquiti, and my wifi speeds are significantly slower now. Still worth it to regain control of my network, though.

That makes no sense. That device is almost bleeding edge and should be just as fast if not faster than your router. Only thing I can think of is the ethernet port out of the modem isn't gigabit and that's why it's slower.

I get full gigabit when wired in, it’s definitely the WiFi that is the bottleneck.

With the Dream Machine built-in AP I get 400-500mbps down, compared to the xFi which got nearly full gigabit speeds. This is with direct line of sight to the access point, maybe 8 feet away.

Similar situation here. The AT&T-provided router for gigabit fiber performs significantly better than my new Ubiquiti "frisbee" access point that's mounted on the ceiling.

At a previous house, I was equally impressed with the WiFi speed and propagation with the stock AT&T router (a different manufacturer), which performed at nearly the theoretical max.

Perhaps ISPs are learning to provide higher end equipment? Of course, gigabit fiber already necessitates better than average equipment, lest you expect complaints from customers.
