I cannot find that exact model Acer (are you sure it's a model "720"?) but
apparently some of the Acer models use the ath9k driver and some freeze
under certain conditions. You listed some specific distros that did and
didn't work, but the other distros may use a different version of the
driver. (Could be newer OR older.)

Here is one of several results from a Google search.

You might want to check to find the EXACT model information of your laptop
and search for it. There may be some more up-to-date recommendations and
workarounds.
