Troubleshooting UniFi and Ubiquiti networking
Ubiquiti's UniFi gateways, switches and access points are managed in the UniFi Network app, which shows each device's status, firmware and port statistics. Restarts and firmware updates are done from the app; a device that will not adopt may need a reset with the pinhole button for about ten seconds. Switches that restart or overheat need airflow and the right PoE budget, and a slow Ethernet link is checked by testing another cable and port and looking at the port's negotiated speed.
