Is there a non described change in ROS from version 4.11 on ethernet for RB450G? We have the same problem on a lot of RB thist type. Link look good but with some errors described as rx-drops. Solution is downgrade to 4.10. Please Mikrotik if it is possible repair this problem. This problem is in 5.x too maybe in x86.
i haven’t seen this problem on 5.3 so far.
I haven’t seen RouterOS 5.3 at all. Where did you got it? The newest downloadable version is 5.2 on official website. Am I wrong?
