Hi Mike,
 
I understand that every situation is different, and, one of my key points
on versatility ot good tools is that even your situation is different today
than it might be five years from now (where you can repurpose stuff you
bought if it's versatile).

Understood. The beauty of the switch (or router) being separate from the
access point is that you can place the access point anywhere you like.
 
One thing you might consider, Mike, which works GREAT for me because I
don't want to 'climb through walls' is you can position the access point
OUTSIDE the house pointing back at the house!
 
This idea works GREAT for me!
 
I'm nestled into the side of a hill, which helps, as I can see the roof
from my back yard, where every instance is different topographically, but
even on a flat yard, you can still paint the entire house with WiFi simply
by snaking a cat5 cable to the clotheslines pole, so to speak.
 
The geometry works out such that one side of the house only has a wall and
windows to penetrate (out here, windows are solar reflective/absorptive by
code).

Understood, Mike, where it's refreshing to converse with someone like you
who has real needs and thinks of real solutions instead of having to deal
with the too many trolls who outnumber us 20:1 who simply post on Usenet
for their own amusement.
 
Given your needs are simply that the antenna needs to be in a different
location from the router/switch, I'm curious of you've looked at those
routers where the antenna itself is easily detachable and relocatable?

This is where Usenet potluck sharing shows its value:
<https://prd-www-cdn.ubnt.com/media/images/product-features/edgerouter-x-versatile-poe.jpg>
 
So I looked up those suggestions for Mike, where the first Amazon hit was:
 
$61.84 & FREE Shipping
o Ubiquiti EdgeRouter X Advanced Gigabit Ethernet Routers ER-X 256MB Storage 5 Gigabit RJ45 ports
<https://www.amazon.com/Ubiquiti-EdgeRouter-Advanced-Gigabit-Ethernet/dp/B00YFJT29C>
Where it was interesting, in the picture to see not only a POE in (which I
have on my switches also), but also a POE out (which is useful as I feel
good tools should be versatile to fit many situations over the years)
o Marketing: <https://www.ui.com/edgemax/edgerouter-x/>
o Specs: <https://dl.ubnt.com/datasheets/edgemax/EdgeRouter_X_DS.pdf>
 
Here's a review of the EdgeRouter X (aka ER-X):
<https://www.mbreviews.com/ubiquiti-edgerouter-x-review/>
 
The first hit of the ER-X-SFP was this:
$92.99 & FREE Shipping
o Ubiquiti Edgerouter X SFP - Router - Desktop - Black (ER-X-SFP)
<https://www.amazon.com/Ubiquiti-Edgerouter-SFP-Desktop-ER-X-SFP/dp/B012X45WH6/>

This is what I love about the idea of coupling a fast but inexpensive
switch to a separate access point, such as is shown in this picture:
<https://www.mbreviews.com/wp-content/uploads/2017/06/ubiquiti-edgerouter-x-6-1.jpg>
 
Note: You can put that NanoBeam NBE-M5-16 either on the POE out port, or,
you could put it on ANY port if electricity is near the location of the
transceiver, where the advantage of the POE out port is that you the
transceiver can be placed in a location that doesn't have mains power.

The one nice thing about all this Ubiquiti equipment is that they're like
hammers and screwdrivers, in that whenever you have a need, they seem to be
versatile enough to do the job well.
 
I don't have the speed needs that Mike has, but I love plugging "stuff"
into a switch where, for example, this is a radio I'm erecting outside that
is connected to a switch inside, which will paint the house from the sides:

Thanks for that purposefully helpful advice on considering this breaker:
o Square D QOB235 2 Pole Circuit Breaker
<https://www.superbreakers.net/2-pole-circuit-breakers/square-d-qob235-35-amp>
 
It would be nice if the circuit breaker fits reasonably well in the front:
<https://i.postimg.cc/63Z0x60t/generac-circuit-breaker-panel.jpg>
 
Where, in the rear, it's less important how things bolt together:
<https://i.postimg.cc/ryNkQQvY/breaker03.jpg>
Where the Carling uses four 10-32 terminal bolts (lug type).
 
I thank you for not trolling, since it takes zero energy for the trolls to
troll while you went to the trouble to find a decent fit, where what I'll
do is trace out a paper cutout on the generator and take it with me to Home
Depot or Ace to see if the $30 "Square D QOB235 2 Pole Circuit Breaker" can
be retrofitted into that front panel hole.
 
Thanks for spending energy to bring items of value to the Usenet potluck.

Bob:
 
That accretion of slime that is calling itself Arlen G. Holder (this week) should not be trusted with anything sharper than a rubber spoon, much less an electrical part carrying lethal voltages and connecting in any way, shape or form to a residence, or anything else of any value.
 
Further to this, you did its work for it, as it is entirely unable muster the time to find the most obvious information on its own, but will engage in endless blather about the getting of it.
 
Put another way: Don't Feed The Troll.

The main difference between antique & modern violet rays is the oldies use a self-oscillating relay, new ones use electronics to drive the coil.
