Ethernet Issues

I just setup and started running my Jetson Nano, and everything works fine except the ethernet. It is supposed to be 1Gb, and I have 500Mbps in the internet connection, but it won’t run any faster than 40-50 Mbs, and when I use the same ethernet on my other computers I generally get 400+ Mbps on the same cable. I ran a command and ethernet 1000 is enabled but for some reason it just won’t deliver the speed. How can I fix this to be able to use all the bandwidth available ??




What is your method for measurement? From iperf?
