Multiple Eeros with wired connections to the internet
Community, In searching for what I was looking to do, I was unable to find any CLEAR discussions so I thought I would share what I learned here.
I have a large house with many floors, built long ago (1900) and luckily added cat6 in the last go around of renovations. Being an old house, meshing these eeros was a non-starter, I needed to use my wired lan for backhaul to my egress to the internet.
Additionally, I have an existing network and advanced firewall which I wanted to keep, so this write up is assuming bridged mode, which disables a lot of advanced features with regards to policy and user controls.
Step 1: Setup your first eero in a place that you plan to leave it, connect it with ethernet to your lan, set it in bridge mode and update the software to the most current.
Step 2: Plug in your next eero in the vicinity of the first. In the app/network select add eero and follow the steps for placement and upgrade again to current. Once this step is complete you have two eeros in the same "network" using wireless to extend from the first. At this point, you can power down your second eero and move it to where you really want it, where you have a wired connection back to the house lan (and the other eero). Once this second eero is powered and booted, your app will show it as in network and online, using wired as it's connection.
Step 3: Repeat until you are done.
In my case I have 4 eeros and 1 beacon all performing very well but this would not be the case if I were trying to mesh without a wired lan. I also have other devices connected to my wired eeros and they are performing well via the switch/bridge in the eero's themselves. Overall I am very impressed with this platform and look forward to playing more with it!
I should have done an update to this thread sooner but I have been very busy, sorry.
One thing of note, it seems that the eeros are a lot happier if they are all wired to a unique switch or vlan and then egress to the network via a main eero, that main unit having an ethernet link to both the northern switch (wan) and the eero switch or vlan (lan). By happier, it seems that devices can roam from eero to eero more fluidly, I assume doing this masks all wireless devices' arp entries behind the main eero.
To answer kash80's question, adding an eero to an existing "network" while being hardwired in is fine when the new eero can connect to the existing eero wirelessly. My assumption is that the app and the algo that eero use for placement does not look at the wired connection when adding an eero, only focusing on the wireless. Once "added" to the network, the new eero will make use of the wired connection. In my deployment, adding aa new eero to the network would not occur when the new eero was not able to connect wirelessly to the existing eero and the ethernet did not allow it to. I would think the eero folks should add wired eero discovery as a network feature because for me, it never worked. I had to move the new eero closer to the existing network eeros, add it, update it and then unplug it and move it to where I wanted it with a wired connection.
I hope this helps.
