How to choose a WiFi channel?
To be able to communicate with each other, all the components of a WiFi network must use the same channel. For a WiFi network in infrastructure mode, the channel be defined by the access point. However, most people use the default channel. Multiple networks sharing the same frequencies, in the same area, can lead to several problems:
- Slow connection.
- Connection timeout.
For best results, you should configure your access point and clients based on the least used channel in your area. You can use the following softwares to list the WiFi networks and the channels being used,
