推荐测试信号强度的APP
2.2 信号延时
有时候明明信号强度很好但延时却很高可能是当前信道的网络较多。
要判断哪个信道不拥堵可以考虑以下几个因素
信道的使用情况观察每个信道的使用情况特别是附近的WIFI网络和其他无线设备。如果某个信道上有多个网络同时使用那么该信道可能会拥堵。相反如果某个信道上没有或只有少数网络使用那么该信道可能不拥堵。信道的干扰情况除了WIFI网络还要注意其他可能引起干扰的设备如蓝牙设备、微波炉等。这些设备可能会占用特定的频段导致信道拥堵。因此选择一个与这些设备干扰较少的信道可能更好。信道的频率不同信道的频率可能会有所不同。一般来说较高频率的信道可能会有更高的带宽和速度但在传输距离上可能较短5G。因此如果你的设备距离WIFI路由器较近可以考虑选择较高频率的信道。
综合考虑以上因素你可以选择一个较少拥堵、干扰较少且适合你的设备的信道。在给定的信息中你可以观察每个信道的频率和可能的干扰源并根据这些信息来判断哪个信道可能不拥堵。
使用iwlist命令来列出无线网卡支持的所有信道
