@AMW,

Juniper Networks is another company that creates networking solutions for businesses, ranging from routers and APs to full servers. If you do not know what device it is, we would recommend blocking the device until you can find the source.

By blocking the device, you should also be able to see if any devices cannot work anymore or lose their connection. If you have added a network switch, Access Point, or other devices recently, you should look to see if the MAC Address listed in the Deco App, matches the MAC address listed on the Device Itself.

It is possible that an existing device on your network has re-reported its name and MAC to your network after an update, causing the device to trigger e a new device notification.
