**To factory reset a Ubiquiti UAP-AC-Lite access point**, you have **two primary methods**: **Hardware Reset (Physical Button) and Software Reset (via UniFi Controller)**.

**Method 1: Hardware Reset (Physical Button)**

This is the most straightforward method and works even if you cannot access the UniFi Controller.

**Locate the Reset Button**:

The reset button is typically located near the Ethernet port of the UAP-AC-Lite.

It's a small, pinhole button that you'll need a paperclip or pin to press.

**Power On the Device**:

Make sure the access point is powered on (connected to a PoE injector or a compatible PoE switch).

**Press and Hold the Reset Button**:

**Press and hold the reset button for at least 10 seconds (sometimes up to 20 seconds to be sure).**

Release the button once the LED indicator starts flashing or **turning off briefly**.

**Wait for Reboot**:

The device will reboot, which can take a couple of minutes.

After rebooting, the device will be reset to factory defaults.

**Method 2: Software Reset (via UniFi Controller)**

If your AP is already adopted and you have access to the UniFi Controller:

Log into the UniFi Controller.

Go to the "Devices" tab and find your UAP-AC-Lite.

Click on the device to open its properties.

Go to the "**Settings**" tab.

Click "**Forget Device**".

This will remove it from the controller and reset it to factory defaults.

**Factory Default Settings**

After resetting, the UAP-AC-Lite will have the following default settings:

**IP Address:** **Obtained via DHCP** (Check your DHCP server or use Advanced IP Scanner or nmap to find it)



**<wrap hi>Username: ubnt</wrap>**

**<wrap hi>Password: ubnt</wrap>**

  ssh ubnt@<IP_DEL_AP>
  set-default
  reboot
  ssh ubnt@<IP_DEL_AP>
  syswrapper.sh restore-default
  reboot
  ssh ubnt@<IP_DEL_AP>
  set-inform  http://10.210.108.66:8080/inform
  reboot

----


**WLC:**

  service unifi restart
  systemctl restart unifi

----


Default Web Interface IP: If no DHCP is available, **the default IP is usually 192.168.1.20.**

**Re-adopting to Controller**

**After resetting**, the access point will appear as "**Pending Adoption**" in your UniFi Controller dashboard. You will need to **re-adopt and re-provision it to make it functional again within your network**.


----
----

**Access the UniFi Controller**

Log into your UniFi Controller dashboard. This can be:

  * UniFi Cloud Key
  * UniFi Network Application running on a local computer or server.
  * UniFi Dream Machine (UDM / UDM-Pro)

----
----

**Check for Pending Devices**

Go to the "**Devices**" tab on your **UniFi Controller dashboard**.

Look for your UAP-AC-Lite under the “**Pending Adoption**” or “**Disconnected**” section. It should show up with its MAC address.

If it doesn't appear, make sure:

**It’s properly powered and connected.**

**The network segment is reachable by the UniFi Controller.**


----
----

**Adopt the Access Point**

Click on the** device’s row** to open its properties.

Click on the “**Adopt**” button.

**The device will start provisioning**. This process can take a few minutes.

Once completed, the status will change to “**Connected**”.


----
----

**Re-Provision the Access Point**

After adoption, the UAP-AC-Lite may require a firmware upgrade. You can do this from the “**Devices**” tab by selecting the device and choosing “**Upgrade**” if an update is available.

Configure your wireless networks (**SSIDs**) and ensure the AP is part of the correct Wireless Network Group.

**Apply** the settings and wait for the AP to provision.

Check the device status to ensure it is “**Connected**” and functioning properly.


----
----


**Test Connectivity**

Connect a client device to the Wi-Fi network and check Internet access.

Optionally, use the UniFi Controller Dashboard to monitor client connections and signal strength.


----
----

**Troubleshooting Tips**


If the device does not appear for adoption:

Check if it's powered correctly (**PoE port should be providing power**).

**Ensure the AP is on the same network segment as the UniFi Controller.**

Make sure port **8080** and **8443** are open on your network for communication with the UniFi Controller.

If adoption fails repeatedly, consider performing a hardware reset again and retrying.
