Dark tinted windows are aluminized mylar. The aluminum acts as a
great RF shield. Very little RF of any frequency (including cellular)
will go through that.

Plastic or metal electrical boxes? Big boxes or small boxes. More
than one box? Any big block of metal will cause problems. However,
there shouldn't be anything radiating from any electrical box that
would affect connectivity or signal strength.

That's a good indication that the electrical box was not at fault.

Numbers please, not descriptions. How far away in feet (or meters)?
How big an obstruction? Have you checked the Fresnel zone clearances?
What type of antennas?
Dry wood does not normally cause a problem with 2.4Ghz. Wet wood is
another story. It's quite a good shield.

Not really. I work with numbers and you've supplied none. Check your
signal strength and your signal to noise ratio. If you don't have
enough signal, it's because you're either too far away, too many
obstructions, or insufficient antenna gain. If possible, add some
external directional antennas which always improve the situation. If
you're using the stock antennas, start with these reflectors.

If the noise level is too high, then it's possible you're hearing some
interference. Look around with Netstumbler or Kismet for other
wireless systems that might be causing inteference.
