Most of the time, devices are already pre-configured, so you don't need to configure them. That configure.me may belong to a neighbor.
What I recommend you is to take a look at the following guide where shows the most common setup to make sure the wired is ok.

If that devices is the only one having issues connecting to the network can be a Radio problem that can be adjust.
To make sure that are your devices 'configuration' ( your access points/ white boxes on your ceiling ) , we recommend connecting to your local ISP router via Wi-Fi or ethernet and scanning or tracking the IPs of your devices ( IP address or IP are logical addresses given by your router)
