Anybody use a mesh network in Puna?

[terracore]

My wifi coverage isn't sufficient and I'm looking at upgrading to a mesh network. So many options and prices it boggles the mind. After skimming the research I've learned I probably had unrealistic expectations of what to expect from a standard router. I'm thinking about putting a node outside in a well sheltered area (like under the eaves) to extend the range further from the house but not sure if the Puna humidity will just quickly kill it. I'm guessing whatever I choose will be obsolete in a few years anyway.
