UniFi – How to Reset the UniFi Access Point to Factory Defaults

Overview

This article describes different methods of resetting a UniFi Access Point (UAP) to factory defaults. We’ll discuss options to reset the unit via the UniFi Controller software, SSH, and physical reset. This article applies to all models and versions of UniFi Access Points, the location of the reset button in each different model may vary. Reference the specific Quick Start Guide of each product to locate it.

ATTENTION: Regardless of the method used, do not disconnect the device during the reset process.

UniFi Controller Reset

If the UAP has been adopted by the UniFi Controller, it can be reset from the controller. Do so by “Forgetting” the device.

Log in to the UniFi Controller. In the Devices page, click on the UAP you wish to reset. This will open the Properties panel.
Select the Configuration tab, and click Manage Device to expand.
Click the Forget button. This will erase all configuration and history for that device, effectively resetting it.

SSH Reset

Access the UAP via SSH, and once in, issue the commands syswrapper.sh restore-default and hit enter. The UAP should quickly reboot with factory default settings. Remember to not disconnect UAP from power source during this process. See Related Articles below if you need guidance on how to SSH into a device.

Physical Reset

On the back of the UAP there is a small hole whereby a user can use a paperclip to depress a button and reset the UAP back to its factory default settings.

Press and hold the reset button for 10 seconds while AP is connected.
Release the button (the LEDs on the UAP will stop glowing).
Do not disconnect the UAP from its power source during the reboot process.
The UAP will restore factory settings.

Once the white LED (or amber LED, depending on your model) re-appears and remains steady, you can commence with UAP adoption once more.

NOTE: The location of the reset button might vary on different UAP models, find your device’s in the Quick Start Guide.

This Knowledge Base article will show you how to set up your IOS device in order to use OpenDNS.

Note:

These instructions only work for Wi-Fi connections because iOS does not allow you to change the DNS servers when connected to cellular networks. Also, the changes are network specific, so you'll need to change the DNS servers every time you connect to a new wireless network. The good news is that iOS remembers the settings, so you won't have to repeat these changes whenever you reconnect to a known network.

Also, this works the same on all iOS devices.

Changing your IOS device DNS settings:

From the IOS device home screen, tap Settings.
Tap Wi-Fi, ensure it is enabled and your wireless network is connected.
Click the symbol next to your wireless network, as shown below.
The screen shown below appears. Tap the Configure DNS field.
Ensure Manual is selected and delete the current DNS servers by tapping on the symbol.
Tap Add Server and enter OpenDNS resolvers 208.67.222.222. Repeat this process to add another DNS server as follows 208.67.220.220, as shown below.
Tap Save to exit the menu.
