Sometimes, the best choice is to leave the web connection set to defaults without any changes.
No single channel number is inherently best relative to the others.
However, if neighboring networks do the same, interference and connectivity conflicts result.

Lifewire
TheWiFi Analyzerapp for Android is a good example of such an tool.
Less technical people may test each wireless channel individually and choose one that seems to work best.
Often, more than one channel works well.

Periodically monitor your environment to see if conditions have changed such that a Wi-Fi channel update makes sense.
Most router screens provide a drop-down list of supported channel numbers.
The same configuration screens can be checked at any time to verify the numbers in use.

5 GHz Wi-Fi Channel Numbers
The5 GHz band offers more channelsthan 2.4 GHz Wi-Fi.
The highest-frequency channel (165) operates on 5.825 GHz.
Neighboring Wi-Fi home networks that run over the same channel generate radio interference that can cause internet performance slowdowns.
Reconfiguring a web link to run on a different wireless channel helps minimize these disruptions.
Some Wi-Fi gear, particularly older devices, may not support automatic channel switching.
