Action camera owners DJI Osmo Action 3 (often mistakenly called the X3 Plus) periodically encounter a situation where the wireless connection stops working correctly. This may manifest itself as an inability to connect to the app. DJI Mimo, constant signal drops, or a complete loss of network connectivity on your smartphone. In such cases, the most effective solution is a complete reset of the device's network settings to factory defaults.
Restoring the original network settings doesn't require complex equipment or extensive technical knowledge. Simply follow the correct sequence of steps in the camera's menu. It is important to understand, that after performing this operation, the camera will forget all previously paired devices, and you will have to re-enter passwords to connect.
In this article, we'll detail a step-by-step process that will help you quickly restore your camera's wireless module. We'll also cover common errors that occur during setup and how to resolve them without calling a service center.
Preparing for the factory reset procedure
Before changing system settings, make sure your device is ready to use. Charge the battery. DJI Osmo Action 3 to at least 50% to avoid sudden shutdown at a critical moment. A low battery can interrupt the module initialization process.
Make sure the memory card MicroSD It's installed correctly, although it's not critical for the WiFi reset itself; the system may check the drive's status during a reboot. If the memory card is damaged or locked, the camera may behave erratically, which is sometimes mistaken for a problem with the wireless module.
It is also worth installing or updating the application in advance. DJI Mimo Update your smartphone to the latest version. Older software versions may not work correctly with the new data transfer protocols used by the camera after a reset.
Step-by-step instructions for resetting via the camera menu
The primary method for restoring factory network settings is performed directly through the camera's touchscreen. This is the most reliable method and doesn't require a computer connection. First, turn on the camera and wait for the main interface to load.
Swipe from left to right on the screen to open the quick settings menu and select the gear icon to go to the section SettingsIn the list that opens, find the item Net or Wireless Connection, where the WiFi and Bluetooth parameters are located.
In the network menu, scroll down to the very bottom of the list. There you will find the option Reset network settings (Reset Network Settings). Clicking this button will prompt the system to confirm the action. This is a protective measure to prevent accidental deletion of important data.
☑️ Factory reset algorithm
After confirmation, the camera will automatically restart the wireless module. The screen may go blank for a few seconds. Don't panic; this is normal system behavior when updating network interface configurations.
⚠️ Attention: After the reset, the WiFi network name and password will return to the factory defaults. These are located on the sticker located on the bottom of the camera body or on the device box.Using a button combination for Hard Reset
In situations where the touchscreen is unresponsive or the system is frozen, you can use a hardware reset. This method is also known as Hard Reset network modules. This is especially useful if the software interface is unavailable.
To perform this procedure, simultaneously press and hold the mode button and the power button (or the action button, depending on the firmware version) for 10-15 seconds. The camera should vibrate or beep, confirming that it has entered reset mode.
Release the buttons when you see the status indicator flash in a specific pattern. This means the camera has cleared the temporary network configuration files. After this, the device must be completely powered off and then back on.
What to do if the buttons do not respond?
If the camera is completely frozen and unresponsive, try removing the battery for 10-15 seconds, then reinsert it, and immediately try the button combination. In rare cases, connecting to a USB-C power source is required to activate the controller.
This method doesn't always reset all camera settings, such as video resolution or frame rate, but it does clear the Bluetooth and WiFi connection cache. This can resolve the issue where the phone "sees" the network but can't connect.
Setting up a connection after a reset
After successfully completing the reset procedure, you will need to re-establish the connection to your smartphone. Open the app DJI Mimo and enter camera connection mode. Since the old data has been deleted, the phone will detect the device as a new one.
Select your camera from the list of available WiFi networks. By default, the network name contains the device model and the last digits of the serial number. Enter the password found on the camera's housing. Be careful when entering it: the password is case-sensitive.
Once connected, the app may request permission to use the local network. Be sure to agree to this request, otherwise video streaming and camera control will be impossible. In some cases, you will need to disable mobile data during the initial setup.
Table of typical errors and ways to solve them
Even after a proper reset, specific errors related to device compatibility or interference may still occur. Below is a table to help diagnose the problem based on the error code or symptom.
Symptom / Error Code Probable cause Solution WiFi won't turn on (gray icon) Module driver failure Factory Reset Error 1002 when connecting Incorrect password Check the password on the sticker, reset the network The phone does not see the camera network. 5GHz band is not supported Switch the camera to 2.4GHz in the settings Connection lost during transmission Interference from other devices Move closer, remove sources of interference If the error persists after following the recommended steps, the issue may be hardware or software version conflict. In this case, it's worth checking for firmware updates.
⚠️ Attention: The menu interface and item layout may vary slightly depending on the firmware version installed. If you don't see a menu item, check for updates in the sectionAbout the system.Firmware update as a method for fixing bugs
Often, WiFi problems are caused by software errors in the current version of the camera's operating system. DJI regularly releases updates that fix vulnerabilities and improve connection stability.
To update, connect the camera to your smartphone via the app or use a computer and card reader. Download the latest firmware file from the official website and copy it to the root of the memory card. The camera will automatically detect the file when you turn it on and prompt you to update.
The update process may take 5 to 15 minutes. During this time, do not turn off the camera or remove the battery. Interrupting the data transfer to the ROM may prevent the device from turning on.
Frequently Asked Questions (FAQ)
Will setting up WiFi reset my videos and photos on the memory card?
No, the network settings reset operation (
Reset Network Settings) affects only the configuration files of the wireless modules. All media files stored on the memory card or internal memory (if applicable) will remain intact.What WiFi standard does the DJI Osmo Action 3 use?
The camera supports dual-band WiFi, operating in both frequency 2.4 GHz, and in 5 GHzFor high-resolution video transmission (4K/60fps and higher), 5 GHz is recommended, but 2.4 GHz is better for long-distance stability.
What should I do if the camera doesn't see the 5 GHz network on my phone?
Some smartphones, especially older models or versions for certain regions, may not support the 5 GHz channels used by the camera. In the camera's WiFi settings, force the band to 2.4 GHz for maximum compatibility.
Is it possible to reset the settings without accessing the menu if the screen is broken?
Unfortunately, without access to the touchscreen, performing a precise reset of just the network settings is difficult. However, if the camera powers on, connecting it to a PC via USB and using software utilities to reset it is possible, although this is less reliable than using the menu.
Does cold weather affect the operation of the WiFi module?
Yes, at extremely low temperatures, antenna efficiency and battery life are reduced, which can lead to a weakened signal. Under these conditions, the WiFi range can be significantly reduced.
