True. I know a number of average users that also do what I am doing, however.

Only if the 5Ghz and 2.4Ghz networks are on the same SSID.

I don’t do that… I maintain separate 5Ghz and 2.4Ghz SSIDs. This allows me to know
which one I am on and force when desirable (usually forcing 5Ghz is desirable).

Customer devices will see the higher signal on the 2.4GHz AP and simply connect to that, especially as they roam 
through the house. Most don't pay attention to SNR at all.

I think that was Josh's point, that 5 GHz will likely deliver better RF performance than 2.4 (despite physics) due 
to the amount of interference in 2.4.

Count in oversubscription rates for residential, and consider that most
people, despite what they say or think, will end up on 2.4GHz wireless in
the home due to 5GHz sucking more than a room away - that ends up being a
very scalable solution for residential service.

Um… 5GHz works a lot better from one end of my house to the other than 2.4Ghz
due (in large part) to this fact… Almost every one of my neighbors is using
various 2.4GHz devices including about 45 external SSIDs visible from the
center of my house using the on-board antenna of an ESP8266 board from Adafruit.

The noise floor and congestion on 2.4GHz in many urban settings, especially here
in Silicon Valley makes 5Ghz a much better option in any home where people are
smart enough to pay attention to the difference.

OTOH, since the WiFi consortium took away the ability for consumers to easily
differentiate (it’s all “n” or “ac” now regardless of frequency) and you have
to really read the fine print on the side of the box to find a 5Ghz capable
WAP at your local big box store, most consumers end up on 2.4Ghz because those
are the least expensive routers on the shelf.

Personally, I don’t mind this, but I think the 2.4Ghz prevalence has more to do
with consumers not knowing what they are buying than it does with performance.
