Probably about time for an MT staff comment...I received one today and opened it, updated it to 5.20 run for about 3 hours and BOOM lights blinking. Should i get another type router.
Done. Thank youplease contact support@mikrotik.com and write the Serial numbers of thos board so we could check if they could be affected by that problem....but only temporarily, unfortunately. Went into seizure mode after 2 days in service.
