Wireless upstairs or downstairs

I overheard someone saying either wireless traveled better UP or
Down. I moved my wireless modem upstairs and am not getting an
excellent reception. I got better reception upstairs than I am
getting downstairs when the modem was downstairs. Reason the modem
was moved is because desktop is hardwired to router and we moved it
into my son's room.

So does anyone know if the wireless modem works better for the full
house located down stairs versus up stairs? Thanks.

If the antennas are mounted straight up, the radiation pattern looks
like a fat donut, so they work better if all in the same horizontal
plane.

Last time I checked, RF and electromagnetic waves are not affected
(much) by gravity (ignoring gravitational lenses and relativistic
effects).

Well think about what you're going through going up and down. Going
down, you're probably going through the desk or table that the
computah is sitting on. That's not the case going up. Similarly,
there may be differences in what's stuffed in the ceiling and floor.
One may have aluminum backed fiberglass insulation, which is fatal ot
RF propagation. You may also have an open stairwell, which is closer
to either up or down. Hard to say without a site survey (walk around
with a signal strength indicator).

It would stand to reason that since the RF waves are lighter than
air, then they'd travel upward effortlessly.

Not true. You see them 200 ft tall cellular towers? The radio
waves fall down to reach your cellphone.

That's because the waves are specially designed to bind with
carbon dioxide in the higher atmosphere, causing them to drift
downwards and get into those low-lying areas between peaks more
effectively, helping to prevent dead spots.
