Event message:
- [Interface]: connection speed goes to [100 Mbit / 10 Mbit] 
Explanation:
The data transfer rate has changed. The cause for the status [10 Mbit] can be a defective plug, a defective cable or the pulling or plugging of the network connector.
Corrective measures:
- Ensure that with an Ethernet connection, the network cable and the network connector are not damaged and that the network connectors are correctly plugged. 
- Ensure that the DHCP server (router) and any network switches are signalizing correct operation.
