How to tell if the ethernet connection is trained at gigabit?

How can I tell if the ethernet connection to my modem is gigabit or if it downtrained to something slower?

When I direct connect a laptop to my cable modem, I get download speeds in the 140-150 Mbps, but through my Eero that drops to 60-80.  I'm wondering if I am only getting 100Mbps ethernet to the modem, but can't find a way to tell in either the Eero or the cable modem.

  • Here's a link that walks you through the steps. Hopefully the external link is allowed.



  • Thanks for the link, JTswift !  cheezedawg let us know if that link is sufficient or if you need further assistance... and thanks for joining the eero community!

  • Actually, no, that is not what I am looking for.  I'm looking for the speed of the connection between the cable modem and Eero, not the speed that my PC is connected to the internal network.

  • cheezedawg My apologies, but after reading your original message and your response I am not sure I understand exactly what you're looking for.

  • Cheese,

    I don't know of any way to see the link speed between the gateway eero and your modem.  I do see what you're asking now, though.

    The speed difference you're seeing shouldn't happen with that kind of direct connection. I think your best troubleshooting bet would be to swap Ethernet cables around. You may have an old or bad cable if your speed is dropping like that.
