By default, it seems that the ethernet port on RPi 2 is 100 Mbit.

Is there a way (via software) to enable 1000 Mbit ethernet?

I also have the same question for RPi 3, and RPi 4.

  • The best place is to see the specifications on the RPT/RPF product pages at raspberrypi.org/products. Here they detail the Ethernet connections such as on the 3B+ Gigabit Ethernet over USB 2.0 (maximum throughput 300 Mbps) The quickest throughput so far I've seen (Nov 20) is the Compute 4 board running an external network card youtu.be/a-0PeuPINiQ - As this data is readily available (inc many max vs actual articles on the web) I'm voting close on this. – user115418 Nov 15 '20 at 14:12

    I’m voting to close this question because data rates readily available via web search and subject to change as new models / adapters tried with software tweaks (e.g. MTU / Jumbo Frames / Kernel Drivers) – user115418 Nov 15 '20 at 14:13
  • @Andyroo Indeed raspberrypi.org/products/raspberry-pi-3-model-b-plus shows Gigabit Ethernet over USB 2.0 (maximum throughput 300 Mbps); what does this mean exactly? – Basj Nov 15 '20 at 15:38
  • @Andyroo "Available via web search" is true for many many many SE posts, but evil is in the detail. As said before, even in the official spec page raspberrypi.org/products/raspberry-pi-3-model-b-plus/…, it is not very explicit: is "Gigabit Ethernet over USB 2.0 (maximum throughput 300 Mbps)" about using an external USB ethernet adapter? Then what about the built-in ethernet cable? It is not written on this page. – Basj Nov 15 '20 at 15:40
  • The max through put means you can get a maximum of 300 Mbs though the link - the port follows the Gigabit cabling and electrical standards (OSI Physical Level) lifewire.com/layers-of-the-osi-model-illustrated-818017 As for external adapters - that depends on the adapter see the video for max throughput – user115418 Nov 15 '20 at 16:23

Only the Pi4 can do 1 Gbit over the built in ethernet.

  • Thank @CoderMike for this answer. Can you add an authorative source to your answer with links? For example raspberrypi.org/products/raspberry-pi-3-model-b-plus/… is not very precise ("Gigabit Ethernet over USB 2.0 (maximum throughput 300 Mbps)"). – Basj Nov 15 '20 at 15:42
  • @CoderMike - That is such a wooly answer that its virtually pointless. Do you mean physical connection of data speed? Also the Pi 400 has a Gbit adapter :-) – user115418 Nov 15 '20 at 16:25
  • @Andyroo The question only asked about Pi2,Pi3 and Pi4. – CoderMike Nov 15 '20 at 18:06
