Hello . Please tell me how to limit the range of WIFI my router (GL-AR750S or GL-E750) ? For example, I want my router to have a distance for WI-FI of 1-2 meters. What settings in luci allow me to do this?
You need to reduce the Wi-Fi tx power. If you only need a signal within 2 metres, try minimising it in LuCI.
You need to set the wifi txpower to 0, which is 1mwatt
Wi-Fi networks have a range that’s limited by the frequency, transmission power, antenna type, the location they’re used in, and the environment. So the exact calculation is very complex. You can refer to: Understanding Wireless Range Calculations.
But I think it may be more easier for you to try it more times.
