Rock Pi 4B only 100MB Lan Speed

[Hubär]

I used iperf3 to monitor the LAN perferomance.  It seems the LAN Port only runs on 100 Mbit

how can I get a 1GBit speed ?

Hello! I am facing the same 100M ethernet speed issue. The TP-Link switch I have auto-negotiates the Rockpi 4B to 100M link speed instead of 1000M. If I manually set it to 1000M in my switch, the link stays down.

 

From ethtool

 

 

The internet speed is affected too. It used to be around 98 ~ 104 Mbits/s

 

 

I noticed this behaviour after upgrading from 23.8.1 to 23.11.1

 

EDIT: A combination of a new ethernet cable and Switch firmware update resolved the issue for me.
