RouterOS General
1

Hi
After update RouterOS to 6.40 on Mikrotik RouterBoard RB 2011 UiAS-2HnD-IN LCD screen after boot is blinking.
Dont matter is ON or is OFF
Blinking with status led of ether1 alternately
If I unckeck or ckeck “Enabled” option - blinking stoped.

If I unplug UTP cable from ether1 and put in other ports then blinking stopped. If i plug in back then blinking started again.
