What is Interference Monitor and how to use it?

Wireless transmission is limited resource. Wireless connection and performance, as well as searching SSID will be easily affected by the congestion of the channel. Since firmware version 1.2.0, VigorAP supports Interference Monitor (AP910C will support this feature in further version). Users could refer the information of this tool to understand the performance and stability of their wireless environment.

Interference Monitor can scan the channel that AP is using currently, or to scan all the available channels. We can refer to Channel Utilization and Channel Energy to distinguish the less crowded channel. Both of these two value can represent the congestion of the wireless environment, but with the different meaning.

  • Channel Utilization indicates the congestion of the channel, it can be understood as how heavy the traffic is through this channel currently.
  • Channel Energy points out the strength of electromagnetic field, it can be transmitted from other APs or background noise in the environment. Background noise will come from wireless devices and all of electric appliances around us, like the air conditioner, microwave, TV, even the electrical wire may make the noise.


Here is the example to scan the Current Channel which the AP is currently using:

We can click "All Channels" tab to scan all the channels available in your country. Vigor AP will provide the recommended channel to use which is calculated with the values of Channel Utilization and Channel Energy. Please notice that VigorAP needs to switch and listen to different channels for a while, no station is allowed to connect with the AP during scanning process.
