# Resolve UniFi Access Point Blinking and Hidden Base Unit Location

## Problem

A dental office reported a UniFi access point that blinks on and then goes off by itself. The office staff believed they only had one UniFi device (the blinking access point) connected via ethernet to a modem near the front desk PC. However, the UniFi portal showed WiFi was still active and devices remained connected to the network even when the visible access point was disconnected. The office could not locate any UniFi base unit or controller.

## Resolution

1. **Identify the actual network topology** - The UniFi Network Controller interface shows an **AC Pro** access point serving clients, indicating there is a functioning UniFi system beyond the visible blinking device.

2. **Locate the hidden UniFi controller** - Check for:
   - A UniFi Cloud Key or Dream Machine in network closets, server rooms, or mounted in less visible locations
   - Software controller running on a server or workstation (accessible at `127.0.0.1:8080/manage/` as shown in the portal)
   - UniFi base station that may be wall-mounted or ceiling-mounted in areas not immediately visible to office staff

3. **Verify the blinking device identity** - The circular white device with the "C" logo appears to be a different brand (possibly Cambium Networks) rather than a UniFi access point, which would explain why disconnecting it doesn't affect the UniFi network.

4. **Check the UniFi controller for device status** - Use the online clients view to identify which access point is actually serving the network and locate it physically based on signal strength or client connections.
