>> The major benefit of Ethernet is now gone.
Not sure about that.
Despite those content viewing content on their mobiles, the market will consume the best formats and bit rates available. And fiber to the home with Cat-6e/7 cable will deliver. Wifi tends to lag. Disagree?
The most you get out of older laptops with 802.11ac routers is 802.11n, although you get some distance boost.
In my experience, only the newest equipment will approach 1G/sec, and mostly only in the same room, or one adjoining.
The cost per megabit/sec is also not yet competitive. I have this equipment because I can write it off and I'm a gadget freak. A $400-$500 5300ac gaming router is not for most home/home office budgets, and even the "slow" 1900ac routers are pushing $200.
Finally, I would say if you do backups (I do full monthly backups and nightly differential backups of all the computers in my home and office) 1G or 10G ethernet is a better solution. Comcast routinely delivers (only) 215 Megabit/sec down, but the cable company is not my bandwidth limitation.
Since I don’t know what you’re talking about, what’s to disagree? LOL
