Hy Everyone!

We have an Omada system with 19x EAP225 with OC300. 

About 2 weeks: 2 devices randomly disconnect according to my omada application. One is connected via cable and the other to another EAP225 in a mesh network. I haved tried the 2 EAPs reset-reconfig but the problem isn't solved. 

Mesh AP: 10-27-F5-37-29-A6

Wired AP: 00-31-92-E7-12-BA <- this connected to TL-SG2008P v1.0 1000 Mbit.

I hope I attached the good log, thanks a lot:
