Controller also lose connection to those accespoints. But if i try to ping AP-s from any computer in company there is still ping timeout, high ping numbers.
At this time if i ping controlloer itselfe there is no problem at all.
So the main problem are those AP.
Yes there is a log, but all i have is that AP is down/unable to connect... Nothing more..
Also i have somwhere around 200 network devices (pc, laptops,printers,PLC) and they all work fine when i have this problem with those AP.
