All Wi-Fi network devices communicate via specific wireless channels that are indicated by a number. Under normal circumstances, you do not need to worry about these settings, but if you want to change the Wi-Fi channel number to avoid interference, you can do so.
Choose the right channel for your WiFi!
In many environments, Wi-Fi connections perform equally well on each channel. Sometimes, the best choice is to leave the network at its default settings without any changes. However, performance and reliability of connections vary from channel to channel, depending on sources of radio interference and frequencies. No channel number is inherently better than the others.
In the US, for example, some people prefer to configure their 2.4GHz networks to use the lowest (1) or highest (11) possible channels to avoid middle frequencies, as some home WiFi routers default to the middle channel 6. However, if neighboring networks do the same, this will cause interference and connectivity conflicts.
In extreme cases, you may need to coordinate with your neighbors to determine which channels they use to avoid mutual interference.
