Hi Folks!

Know this is going to have answers with "could be" which is better than
what I'm coming up (and so why posting).

Was playing with two Raspberry Pi's, one the 3B (only the 2.4 GHz bnad) and
the other a 4B (2.4 and 5 GHz bands).  The WiFi dual band Access Point is
up here in the Computer Room, essentially top-center of the house.  Both
Pi's connected fine when testing up here.  Both Pi's had troubles
connecting/maintaining a connection when downstairs, so one story down
and 1« rooms over, through wood.

Test the signal strength with an app on my cell phone.  Up here pegging
(better!), downstairs a little over half -- 60%?  Should be more than
enough signal, plus was notably stronger than the neighbours' signals.
Wandered a bit looking for dead spots or dips - nothing.  The 2G signal 
is sometimes slightly better than the 5G at time, usually 5G better.

I'm not seeing anything giving me a reason why works fine up here and
spotty downstairs.

On a whim switched to the WiFi from the ISP's ONT (? essentially their 
router) -- no connection problems!  Only tried wih the RPi 4B (at that 
point in trials and testing I thought the problem was the RPi 3B was too
slow and/or the data stream was overwhelming the critter).

So any ideas/suggestions as to why the connection issues?  TIA!
