For those who may be interested. The Wifi at our park is serviced by
pole mounted APs with a range of 1.5 miles. These are directional antennas and have to be located close the main router. Obviously, I could not service every RV in the Park. So, I installed a pole mounted Range extender and covered about 70% of the guests. I had thought to continue that technique but it was getting counter productive.
So, I decided to think a bit and realized that with my park fully on PL, I did not have to have all my APs at a central location. This is a major plus and resolves a lot of issues with trees, blockages, etc. Now I can relocate my AP towers and ensure everyone gets adequate Wifi.
Will continue to report on this if there be an interest.
