It sounds to me they are abandoning wireless routers all together. It doesn't make sense to me they would only build AIO router-accesspoint-ATV.
I can't say I'm entirely surprised. There equipment is becoming dated and has always had a substantial price tag over mainstream networking brands. Furthermore, a lot of ISPs at this point give out their "wireless gateway" (modem/router/access point).
MESH networking appears to be all the rage. I just discovered the Ubiquiti offshoot brand Amplifi. I used their commercial/prosumer line of UniFi products at my work and love the results.
Ubiquity had been around for a few years now and are target towards the big house/SOHO/medium biz/education sector. They're products tend to have great design, user interface, extensive functionality, and are priced well below that of companies like Cisco, Aruba, etc or even commercial grade Netgear.
They're a quirky British company but have top notch support community. Their UniFi controller software has a built in support chat client with actually pretty knowledgable people on the other end. I will say their product supply line seems a bit inconsistent and at times it's hard to find a specific product anywhere. In my experience/obsveration you usually have to shop around at least a couple stores to get what you need at the best price.
I'm pretty interested in their new MESH Amplifi lineup. It looks gorgeous (who ever thought a wifi system would be asethically pleasing). For $199 you get a base station with two mesh antennas ("10,000sqft"). $299 provides the same thing with long range antennas. $349 buys you the "high density" antennas ("20,000sqft"). PC World did a review on it and had great things to say- excellent coverage and overall faster speeds then Luma and Eero.
Bad news is currently Amplifi is only shipping the 3 afforementioned kits. The additional MESH nodes/access points are not yet available. Typical Ubiquiti silliness. I'm sure they'll be out eventually.
There you have it, one elegant base station and two additional MESH antennas that conveniently plug into wall outlets. $199-349 depending on how powerful your antennas.
I sound like a salesman here... Maybe I need to invest in this company? I will say they make some innovative products. I'm consider this as a Hanukkah gift to my parents as their 5000sq ft house is still using old school Linksys WRT54 2.4ghz b/g antennas. In terms of consumer MESH systems it's the best I've found.
