WIFI mesh leaf AP disconnected

Hi WaltDjr,

Thanks for your info.  Please keep me posted if you guys get any update from tech support.

As a workaround, we scheduled a script to de-authorize the APs and authorize them again at the midnight everyday.  It does help to keep the APs online during the daytime.

did a quick search for the error message and one found in capwap module.

 

almost all fortios daemons have debug flags that can be set "diag debug application <daemon> -1" to enable all debug type bit fields (could result in lot's of debug printout and slows down device or network hiccup) to get more details

 

the error message could be due to config download timeout, client response timeout, etc., mostly in the fsm (finite state machine) transition events timeout but not familiar with the capwap code/logic.

 

support will sent the ticket to dev responsible for the capwap module.

Hi Darwin,

Thanks heaps for your info.

I've changed the timeout values as biggest as I could, like below:

config wireless-controller global set max-retransmit 64     ### 64 is the max one

config wireless-controller timers set echo-interval 240       ### 255 is the max one, but 240 is big enough I reckon.

But it seems don't help. we still have this AP disconnect issue, even after I upgraded the Firmware of FW recently.

I am doubting it could be a bug.
