If all AP's are on switch, then check switch is not running into problem etc..
Check for power outages..
check in the AP support for the reason for AP reboot...

unknown

the reason of AP reboot is " error heartbeat lost"
all the switch is running on Poe and the switch is specifically for AP only
the problem keep happening on peak hours 8 to 5 office hours..
i already upgrade the zd to latest version firmware..
please help..

unknown

Please Mohd, are you using 1106 or 1112?

unknown

Heartbeat loss is indication of potential network issue between AP/ZD.
Ensure that during peak hours switch is NOT failling...
During peak hours, run a ping test from laptop hooked to that same switch to controller and see how things..
Upgrading will NOT help unless its determined that code is causing problem..
btw how do you recover from the issue? do you reboot switch?

unknown

zd1106 as mentioned in subject of the thread...

unknown

i recover it by reboot the ZD..
sometimes i need to reboot it 2 or 3 times to make all AP connected

I also had the same problem using ZD3000 and T300 APs. The solution to the issue is upgrading the firmware of ZD3000 from version 9.8.3 to 9.12.2.0.101. Since your AC model is ZD1100, perhaps you can upgrade it to version 9.10.2.0.11. Good luck!

Does your switch have logs? If so, look for any PoE messages.

unknown

It looks like you have a building with ground floor, first floor and 2nd floor. What is the maximum and typical length of your data cabling from your AP switch to the APs?

unknown

thank you for the suggestion, i will try and let you know if it works

unknown

i am using unmanaged switch, does it have logs?

unknown

Probably not. What is the manufacturer and model of the un-managed switch? Do you have access to another PoE switch? If so, try swapping the switches and see if the Ruckus disconnect symptoms change.
