How does a Zyxel AP behave when encountering radar?

To utilize more available channels, Zyxel APs open DFS channels for Dynamic Frequency Selection. If the AP detects radar, the following may occur:

1. Channel Vacancy: Upon radar detection, the AP ceases use of the affected DFS channel and switches to a non-DFS channel that is available. This prevents Wi-Fi signals from interfering with radar systems.
2. Temporary Disconnection: During the DFS process, Wi-Fi clients connected to the AP may experience temporary disconnection or instability as the AP changes channels. However, modern APs and devices are designed to manage this transition smoothly.
3. Compliance Checks: Zyxel APs perform regular checks. If radar is not detected within 30 minutes, the AP resumes using the DFS channel. Otherwise, it remains fixed on a non-DFS channel.
