Eero already registered on the network<br /> In case you are trying to add an eero, which is already registered on the network, then that could cause problems as well. You need to erase the router’s data by pressing the ‘reset’ button for 5 seconds to reset the device. After that, configure the router again.<br /> <br /> Poor Connection<br /> Once you configure your router on the network, you should conduct a speed test to check the ideal location for your eero router. In case, the eero is placed far away from the modem, then poor connectivity issues may arise. You can take the help of eero customer service to solve poor internet connectivity issues.<br /> <br /> If you have questions or need any assistance troubleshooting, just visit: Eero Installation - https://www.therouterhelp.com/eero-router-setup/
