Hi I am new to this forum, I am using a CCR2004-16G-2S+ from past 4 months everything was good, but today I seen ethernet port 2 enabled and disabled with in few seconds, IMPORTANT THING IT IS NOT IN USE. Can anyone help me out why this happened? I am attaching screenshots here and sorry for my English.
which version of RouterOS you have installed?
have you updated RouterBoot on system->routerboard ?
I have seen the same problem on a device too close to the “air conditioner”…
Inside, moisture settles on the ethernet port and causes problems…
I solved it by directing the airflow elsewhere.
Thank you for the reply, here is my rb version
