I really wasn't sure what to expect. I do know some folks have success with their fermenter inside a keezer in the garage, while their router is in the center of their home, 20-25 feet away and through a couple walls. I guess I would have thought mine being 18 inches from my router would be decent. And it is actually, for the most part. But as I said, weather does seem to make a difference, but luckily we have an abundance of clear sunny days here.How strong of a WIFI signal do you expect from a Faraday Cage?
