Sagemon Wifi router jumps to the weakest channel
I use a wifi analyzer to check the signal and channel strength for both the 2.4 G and 5.0 G. The analyzer shows the signal strengths are excellent (30 to 40 dBm) however both the laptop and cellphone will lose connectivity or show very poor signal strength. The router channel selection is set to auto for both (2.4 & 5.0), yet auto selects the weakest channel.
If I go into the GUI and manually change the channel to a strong channel, the analyzer immediately displays the new channel as now the weakest of the available channels. As you can see in this image, this is the result after the router showed 149 as the channel Auto selected and the analyzer showed it to be the weakest channel and 36 the strongest. So, I changed the channel to 36 and this is the result.
So, I'd like to know what is going on. Auto appears to default to the weakest possible channel and if I rely on setting the channel, then that channel becomes the weakest.
