As far as I know, in earlier versions on WING (pre 5.8.4) there were some problems with gui after adoption. It was displays some error messages.
What is the WING ver?
Hello Tuan Nguyen
As we see, you have link drops at AP "DF4-164" with mac ends with 03-63-E4.
I advice you check your ethernet to the AP if it's not connected with MCX.
