Have you guys seen this behavior before? Unifi is disconnecting and reconnecting itself, also devices that were connected are being kicked out... already restarted AP twice.

is the controller up to date?

Tech A 2024-11-11 19:08

it was not when i got in to the server, but i updated it... and still acting like that

Tech C 2024-11-11 19:08

are the ap up to date as well? o3o

Tech D 2024-11-11 19:09

People is saying that sometimes the poe injector is the one that causes problems, not sure if it's connected by that way

Tech E 2024-11-11 19:16

i would flag that as a power issue

Tech E 2024-11-11 19:17

like its overloading a poe circuit

Tech E 2024-11-11 19:17

and then it turns off then turns back on again

Tech E 2024-11-11 19:17

u6LR is a big one with powerful radios needs poe+ with a good budget

Tech A 2024-11-11 19:22

thinking kind of the same way... that's for Green Mountain Pediatric Dentistry PLLC

Hey guys, I tried to help them with this, we are trying to connect the TV to the wifi, I see the tv as a client at the AP, but they do not have internet when they try to use it. I asked her to check at her phone, and she told me that she's getting kicked from the wifi. I see that there's another U6 LR Unifi device, but they said that probably that device is not there anymore after they rebuilt the office. We already tried to reboot the devices, and still doing the same thing, I also noticed that the U6 gets grayed ouy, clients get kicked, and then they get connected again. Should we do an onsite visit? If I check the logs of the device, it still restarting by itself.

@all 👀

Tech B 2024-11-12 19:13

Vermont is 6 hours away by car

Tech B 2024-11-12 19:13

Onsite is a VERY last resort

Tech D 2024-11-12 19:33

Any advise?

# Resolve UniFi U6 LR Access Point Cycling and Client Disconnections

## Problem
A UniFi U6 LR access point was experiencing continuous disconnect/reconnect cycles, automatically restarting every few minutes and dropping connected clients from both PD-MAIN and PD-GUEST SSIDs. The UniFi event logs showed repeated automatic readoptions, restarts with varying client counts (0-3 clients), and devices like LGwebOSTV and SCANNER being disconnected from the network. Connected clients experienced intermittent internet connectivity issues and were frequently kicked from the WiFi network. The access point would appear grayed out in the controller interface during these cycling events.

## Resolution
This issue is typically caused by insufficient power delivery to the U6 LR access point, which requires PoE+ with adequate power budget due to its high-powered radios.

1. **Update the UniFi controller** to the latest version if not already current
2. **Update the access point firmware** to the latest version
3. **Check power delivery method**:
   - If using a PoE injector, verify it provides PoE+ (802.3at) with sufficient wattage for the U6 LR
   - If using a PoE switch, confirm the port provides PoE+ and has adequate power budget remaining
4. **Replace or upgrade the power source** if it does not meet PoE+ requirements
5. **Verify power distribution unit switches** are functioning properly and providing stable power to network equipment

The cycling behavior indicates the access point is losing power intermittently, causing it to restart and drop all connected clients before reconnecting.
