问题

超级用户读者IAmJulianAcosta想知道使用更高频率的Wi-Fi频道是否更好：

Today I had to call tech support to have my Wi-Fi channel changed because it was using channel 7, but the guy on the phone told me that channel 1 was “less powerful” than channel 11. He suggested that I use channel 11.

Using a Wi-Fi ****yzer app, I discovered that channel 1 is the least used one in my building, so I ignored his recommendation and asked for channel 1. Was he right? Is channel 11 better?

使用更高频率的Wi-Fi频道更好吗？

答案

超级用户贡献者Mokubai为我们提供了答案：

Channel numbers do not denote power “levels”, so channel 11 is not “better” than channel 1 simply because it is ten digits higher. Wi-Fi does have overlapping channels though, which means that devices do not “want” to be on a channel that is too close to another nearby station’s channel.

For the best results and interoperability (least interference), there are only three channel choices: channel 1, channel 6, and channel 11. Here is an image showing why:

If there are many networks near your location, then you want to choose the channel which has the fewest or weakest signals. If, as you mention, that happens to be channel 1, then that is the channel you should use.
