I'm looking for some advice here or product recommendations. Here is my situation. I live on a farm and we have wifi in the house. And I would like our whole cattle corals to have wifi access for a project I am working on. For simplicity let's say this are is a circle. The beginning of this circle is 200 ft from the house and fares point is a quarter mile from the house. We have a barn that could possibly act as a bridge point. Running 802.11 b/g/n with wpa2 personal. Any recommendations would be nice and any piece of knowledge is welcomed.
