Why can't you plug the eero into a router?

The documentation says that the eero needs to be the "first" device plugged into you Ethernet jack (or modem, I guess), but it doesn't really say why that's the case.

I have a router plugged into my Ethernet jack, and then the eero (and other devices) plugged into the router. I also have the 2nd eero plugged into the router as well (via a MoCA bridge). I've disabled the wifi on the router.

This *seems* to work fine, so I have to wonder why the docs are so explicit that the eero has the be the first thing connected.

My reasoning for not wanting to put eero first is that I'd like to support IPv6, and it appears Eero can't do that fully (could that be implemented as a firmware patch in the future?).

Also, I tried to put the eeros in bridge mode but that made things significantly slower for some reason, so the eeros are in router mode (still seems to work fine!). Anyone know why that is?

Anyone have any insights into this setup and why it's not recommended? Or what topology I should be using here?

  • Hi  ssylvan

    Thanks for reaching out and welcome to the eero community!

    In most traditional setups, the eero should be the first networking device plugged into your modem. For this reason, it is the recommended way for setting up your eero network.

    However, you can absolutely double-NAT or bridge your eeros with another router should you need or prefer to. In your case, since you'd like to use IPv6 on your network, you would need to bridge your eeros to the existing router. It sounds like the configuration you have may cause issues, and I'd suggest that you contact our support team so they can take a look and ensure everything is setup as it should. We can get this setup and ensure everything is working to your expectations.
