Those channels are dfs channels. If you have radar in your area, they're required to move off those channels.

    Hi, plemans.

    Thanks a lot.

    No WiFi AP working with W53 channels is around here as far as seeing the scan result of WiFi Analyzer app..
    So, a DFS rader must be the most possible reason, as you mentioned.

    However, as far as seeing DFS rader location on google map, the nearest DFS rader is 32km away from here. 
    Does a DFS rader affect or cover such a wide range?
    Otherwise, does an informal DFS rader exist around here ?

      Thanks, plemans.


      OK, I understood. You are right.

      Approx. 5km away from US Army base with air port...
      So, a DFS rader, unregistered on google map, must be in the base.

        Fairly likely. Because it includes military radar, weather radar, and satellite communication.
