Right, plus having a spare isn't a bad thing.

Easier to line up/orientate. And I should look up to see what position
the four antennae on my access point should be. Right now straight up,
which probably is good for everything up here but not necessarily down- stairs,
especially as one moves away from underneth -- I half-remember a radiation
pattern like an ice cream cone: rounded at the top and
extending to a point at the bottom.

I'll have to refresh my brain on the various 802.11 protocols. I'll
admit my thinking is "get the newest proven" (bleeding edge isn't bad,
just sometimes doesn't work as expected in real life -- let others take
the chance).

Around here I use wireless where required so not as experienced. The
wired distribution was done years ago and works, plus originally at 1
GHz was a lot faster then the wireless back then.

I also order occasionaly from China (AliExpress, occasionally AliBaba);
miss the old postage prices, though shipping three ELP (brand) cameras
for $18.13 ay around the world isn't bad! The overall cost was much less
than what I could find for domestic purchase,
As for subsidizing China Post, originally interpreted that as meaning the
US Postal Service, later thinking maybe US Government. Read where the
various postal authorities get together, determine pricings, and so
agree to deliver one another's parcels at no additional charge. ...Bet
the final carriers love delivering boxes marked with less postage than
for a post card!

Right -- it didn't make sense. OTOH there is a dead zone: pull the car
in the driveway to beside the house and the FM station I'm listening to
in the car fades out. Isn't a local station, but does happen with
several. Haven't experimented if the same effect with a portable radio. Anyway,
the location of the RPi (the original 3B and 4B) were
potentially in this zone. The other RPi (the one running MythTV) is
roughly on the edge of the Dead Zone -- I've never really defined it.
Did find the "Network Connection" utility I have installed on the MythTV
RPi: it's a built-in utility loaded by various clickings of the top menu
bar. Gives a nice GUI; found a command line version also. Will have to
experiment again -- this time seeing what the RPi sees the app on the
cell phone doesn't.
