Is higher channel better WiFi?

For best results, it is highly recommended to keep the 2.4 GHz channels to 1, 6, and 11 , as these channel settings will allow for virtually no overlap in the WiFi signal.

When using 5 GHz, it is recommended to use at least 40 MHz channel width, as some client devices may not prefer 5 GHz unless it offers a greater channel width than 2.4 GHz.

Given the same transmitter output power, in the absence of ANY interference, the lowest-frequency channel will nearly always be the best . This is because higher-frequency radio waves do not penetrate matter (including air) as well as lower-frequency waves.

Selecting the proper Wi-Fi channel can significantly improve your Wi-Fi coverage and performance . In the 2.4 GHz band, 1, 6, and 11 are the only non-overlapping channels. Selecting one or more of these channels is an important part of setting up your network correctly.
