Forti AP : Control Message Maximal Retransmission Limit Reached

20 odd AP's

all fine

network dropped out yesterday for 5 mins and since then one of the AP's wont come back online

 

FortiAP 231G

Fortigate version 7.2.9

FortiSwitch 124F-FPOE

 

Just get a solid Amber light on the AP for power.

AP 'left' and Control Message Maximal Retransmission Limit Reached

 

Things i have tried

 

1. rebooting the Fortigates

2. rebooting the FortiAP 

3. changing the cable from the patch panel to where the AP is plugged into the fortiswitch

4.running this....

config wireless-controller global set max-retransmit 3 <<<< default - please input integer value (0-64) ---> increase to 25 config wireless-controller timers set echo-interval <1-255> ---> increase to 100 end

 

Still no change.

Plugging the AP directly into the Fortiswitch brings it back online - but need it back out in prodcution round the building.

 

Any ideas please?
