@David-TP hi and thank you for your reply. Too bad such option is missing. I might have to return it since such feature is very basic for me. I always use this option when available and I require this feature because there is no need to have more range than you need and occupy channels interfering with frequencies that can be used by others. Also it is preferable for my network not to be able to be seen by third parties in an unwanted range. When you know the WiFi is not required over a distance why should it be available?
