Hi team, 

 

I have the Unifi CloudKEy Controller and a couple of Unifi AP. 

 

https://www.gowifi.co.nz/wireless/uck-g2-plus.html

 

 

 

Recently I'm getting alerts "UniFi Alarm: AP Radar Detected"

 

Device name: (any one of the 4 AP Names)
Site: Home
Message: AP[80:2a:a8:50:be:b5] detected radar on channel 112 (5560 MHz)

 

I get an app notification and email for these, and some times get one every fre days, and sometimes I get 30-40 alerts in the space of half an hour. 

 

 

 

Is it just picking up other AP's from neighbours houses, or something else?

 

Can I adjust a tolerance on these alert?

 

 

 

Thanks

Looks like you may be using DFS channels - with DFS, if an access point detects radar, it switches off the radio for a short time.

 

If you're running close to the latest UniFi software on your Cloudkey you can use WiFi AI to fix this - pop into your UniFi settings and go to Wi-Fi AI, first turn it on (if it isn't already) and adjust the schedule. I personally have it run weekly on a Sunday:

 

 

Scroll right down the bottom to Advanced and under Exclude 5GHz add the DFS channels:

 

 

Hit Apply and run a scan (you may have to wait a few hours for AI to learn your network if you didn't already have AI activated). It'll switch your access points to the best non-DFS channels for your location.
