If you have an eero 6, eero 6+, eero Pro 6 or eero Pro 6E, then you may want to use it as a gateway router by connecting it directly to your modem.
To find out how to do so properly, you can take a look at this tutorial from Seeking Tech.
How to replace your old eero with a new eero 6, eero 6+, eero Pro 6 or eero Pro 6E
If you are already using an older version of the eero router that you want to replace with the eero 6, eero 6+, eero Pro 6 or eero Pro 6E as the gateway device, then you need to take the following steps:
1. Open the eero app on your phone or mobile device.
2. Make sure you are logged into your eero account.
3. After signing into your account, tap the blue plus icon, which should be located on the top right side of the screen.
4. You then need to tap the “Add or Replace eero Devices” option.
5. Next, you need to tap the “Replace eero Device” option.
6. Select the old eero router that you are replacing.
7. You then need to follow the on-screen prompts to remove the old eero and then it replace with the new eero 6, eero 6+, eero Pro 6 or eero Pro 6E. If you are using PPPoE, then you need to input your information when adding a new eero.
8. After adding the new eero, wait for the router to boot up and connect itself to your eero network. This process can take up to 10 minutes.
Afterwards, your eero 6, eero 6+, eero Pro 6 and eero Pro 6E should now act as the gateway router.
How to change the gateway eero with another eero that is already connected to the same network
If your eero 6, eero 6+, eero Pro 6 or eero Pro 6E is already connected to the eero network but is not used as the gateway router, then you need to do the following:
1. Unplug the modem from the power outlet.
2. Unplug all the routers from the modem as well as the power outlet.
3. Plug the modem back into the power outlet and then wait until it completes its connected to your internet service provider.
4. Next, you need to plug the eero 6, eero 6+, eero Pro 6 or eero Pro 6E directly to the modem and then its power adapter to the power outlet.
5. You can then plug in the other routers as secondary routers in your network.
6. Finally, you need to wait until the eero network boots back up and then reassign the gateway router to your eero 6, eero 6+, eero Pro 6 or eero Pro 6E. This process can take a maximum of 10 minutes.
Afterwards, your eero Wi-Fi 6 router should be designated as the gateway to the secondary routers.
