I found something on the message, but it was beyond my comprehension. Contacting ASUS support may be your best bet on this one I'm afraid unless someone else on here knows.

Do you use the USB port on the router? Do you use Windows share on the PC? (Initial hunches).

It may have something to do with these settings:

https://www.asus.com/support/FAQ/1045028

Since they affect security I wouldn't change them unless it is affecting performance or if you're just curious...

EDIT- I found this document later but it is a lot of reading:

Bro, not this issue. The first thing I do when I set up a new router to disable that. What puzzle me it only appeared twice per day.
