ethernet 1 shows disconnected after working for few days.

RouterOS General
1

Hi there i have a rb411 that is connected to a 8port switch. After working great for weeks it began to give me this problem.

Sometimes it will show that the ethernet port 1 is not connected, and then after waiting for hours then it will go back showing the ‘R’.

I tried to change the switch, also replacing the rj-45 connectors. But then it only works for a few days without any trouble.

The current ros was 4.10 and now i tried to downgrade to 3.30.

But still no luck

Does anyone knows if this is hardware or software problem?

The router’s ethernet 1 connected after 5 hours, now i will test it with the auto negotiation unticked.

I have read it in http://forum.mikrotik.com/t/rb411-ethernet-freezes-no-receive/22193/1

realy hope this will work
