RB220 - 100 mbps not working

Hello,

I have a RB220, where the only functional ethernet speed is 10Mbps. It is running the latest ROS and the latest firmware.

What can I do to get 100 Mbps back ??

Thanks in advance for your input…

  1. Use default-settings for Ethernet configuration,
    ‘auto-negotiation=yes full-duplex=yes speed=100Mbps’.
  2. What kind of equipment switched at the other end (supported standarts, how long is Ethernet cable) ?
  3. How did you perform speed tests ?

Sorry, I didn’t make my self clear:

If trying to connect to the clean, updated and reset RB220 via ethernet, you don’t succeed.

Then you connect via serial interface and change speed settings on the RB220 to 10 Mbps. When this is done, you can connect via ethernet.

The problem happened when it was sitting in a tower. Now it is on my desk…

I think it is a hardware problem, but everything else looks normal ???

What configuration you have for ‘interface ethernet’ ?
What equipment routerboard is connected to ?
