Wi-fi is something I think about every day. I have a low end enterprise wi-fi (unifi) and high end enterprise wi-fi (Xirrus) in my home office network. Six access points, open source firewall appliance (Pfsense/Gateway), and two cable modems allow me to experiment, test and develop solutions for a better gateway.
To give you an idea how hard it can be to figure out how this stuff works check out this Arstechnica article where they found out what they didn't know about testing wi-fi mesh network solutions and how "easy" means different things to the vendors.
Xfinity announced xFi its home wifi solution.
The one company I think will make an interesting Home Gateway move is Amazon. They have Amazon Echo and Fire TV as home hardware. And even bigger is they have AWS with all that cloud experience. There are AWS hardware devices like Storage Gateway.
Google has Google Wifi as a home gateway. Apple has Apple TV.
There is a battle going on for who will own the home gateway to connect all the devices.
My choice is to build my own and have complete control. The trouble is once you go with the home solutions all too often you give up control for easy of use.
