How to setup Frequency correctly

Hello,

I am trying to scan for wireless networks around and then set up Frequency for my Router, which will not interfere with other access points around.

Which value should i look at in the scan results?

-Signal strength?
-Noise Flor?
-Signal to Noise?

Also if the number (for ex. “signal strength”) is higher does it mean it interferes more or less with my router?


Please i was trying to figure it out, but still am new to this and don’t know where to start.

Thanks for your help

Yes i also want to know how to measure these values…i know about ccq if it is less than the throughput is not soo good coz of many reasons but i dont know on what condition do we need to set tx and rx power rate ??

Also what does it mean
Signal to noise
Noise floor
how to measure these two value…i know about the strengh the less value we gain and the large value we lose.
