Before hacking out insulation, I'd try the attic approach first.

Too late. I already did it and without moving the wifi module to be
near the hole, the signal already improved from marginal (a red
indicator LED) to OK (the LED is now yellow). Tomorrow, I will move
the wifi module to be near the hole. I expect a green LED after that.

Final update: I moved the wifi device to right in front of my RF
hole. The LED is green and everything is back to normal. I replaced
the old insulation with non-foil type and covered the hole with the
$15 cover plate a mentioned in previous posts. All is well. Thanks.

Good job.

I will say the metal is on the insulation for a reason. It may be
moisture barrier. Is that important with your shed?

It can't be very important since none of it was there until the new
siding was added. The siding was added for aesthetic reasons - not to
solve any other problems. However, I did add a plastic sheet over the
hole before replacing the fiberglass batt insulation in the stud wall.
I will keep an eye on it in extreme weather (hot or cold) to make
sure.
