Hi Mod,

I think we have timezone difference, so we cannot remote , Can you show me solution for this problem through email , my email is van.pa@tabviet.vn. This morning i tried update new firmware , but it still nothing happened

@Newbie151818 / Van, 

It was pleasure assisting you. 

After removing the cloud URL and using serial number we were able to onboard the device. However, device was going offline after mapping to the AP group, it found to be vlan 100 was missing and after adding it, everything went well. 

Thank you for your time.
