This process will have little impact on the WiFi clients. For this reason, DFS channels are not immediately available when an AP boots.Īs I just wrote, if the AP detects during the boot process that a DFS channel is currently used by a radar, it will mark it as non-available and exclude it from the list of available channels. The Channel Availability Check performed during the boot process can take anywhere between 1 and 10 minutes, depending on which country you’re in. This state will last for 30 minutes, after which the AP will check again if the channel can be used for WiFi transmissions. If the AP detects that a radar is using a particular DFS channel, then it will exclude that channel from the list of available channels. This process is called Channel Availability Check, and it’s executed during the boot process of an access point (AP) as well as during its normal operations. When support for DFS is enabled, it will be necessary for WiFi access points to verify that any radar in proximity is not using DFS frequencies.
