20/40 coexistance
Can somebody please explain me what exactly is happening when "20/40 ceoxistence" is sheched, and when it is not? If it is unchecked, is that means that only 20mhz works, or only 40mhz?
Just leave the option checked. The router will conform to Wi-Fi standards. Besides, iPhones will always insist on using 20 MHz, so the router will comply. You can use Wi-Fi Analyzer for Android or Acrylic Wi-Fi for PC. I'm sure there are other programs.
I WANT to use only 20 mhz, but I thought if I uncheck this coexistence, then it will use only 20 mhz. So basicaly if this is checked, router will use 20 mhz mostly, and 40 mhz when air is clear, and if it is unchecked, then it will use only 40 mhz? So there is no way to tell the router to use ONLY 20 mhz, no matter what?
And is there any way I could check what frequency is on at the moment? I have iPhone, android and desktop pc.
