GL-AR750S dropping regular "kern.warn kernel"

Hi,

Had a look about the forum, but couldn’t see a solution for this.

GL-AR750S is in Repeater mode, repeating a open wifi network (captive portal that requires un and pw where I have a bash script running fine to do).
It just seems to drop our every few hours with the following error recorded in the log:

Sorry I don’t have a clue.
