¶ 1. Check if the "Bind Account" section has a QR code on the interface.
On the main interface, click the "Settings" icon, then click "Cloud Platform" and check if there is a QR code in the "Bind Account" section.

If there is no QR code on the interface, provide a detailed explanation of the situation and supply pictures of the device's cloud platform interface.
¶ 2. Check if the WiFi icon in the upper right corner is properly connected.
¶ 2-1. When Connected:
¶ Troubleshooting:
¶ Step 1: Check Firmware Version
Open the device, Go to "Settings," - "More Settings," - "About Machine," and check if the firmware version has been successfully updated.
If the current version is below 2.3.9, it's possible that DNS issues may prevent connection to the Anycubic server network in some regions.
Follow the steps below to update the device firmware to the latest version.

¶ Step 2: Provide a Hotspot from a Mobile Phone
Turn on the hotspot on your mobile phone and let the device search for the corresponding hotspot signal.
Observe if it can connect to the Anycubic server network.
① If the device can connect to the Anycubic server network using the mobile hotspot,
it indicates that the home network is restricted by the carrier, and you need to contact the carrier to lift the restriction.
② If using the mobile hotspot still cannot allow the device to connect to the Anycubic server network,
it's possible that both the home network and the mobile network are restricted by the carrier, and you need to contact the carrier to lift the restriction.
¶ 2-2. When Not Connected:
¶ Troubleshooting:
¶ Step 1: Check WiFi Signal Strength
Use a device like a phone to check the nearby WiFi network list, ensuring that you can find and connect to your desired WiFi. If not, try the following possibilities:
① Manual WiFi hiding: If you manually hide your WiFi network, this could be one of the reasons for not being able to find it.
② Device too far: Make sure your device is close enough to the WiFi signal source to find and connect.
¶ Step 2: Confirm WiFi Frequency and Channel
The device only supports the 2.4GHz WiFi frequency. If the router only opens the 5GHz channel WiFi, it will result in a connection failure.
Confirm in the router settings whether the 2.4GHz frequency is also enabled.
¶ Step 3: Verify WiFi Account and Password
Ensure that the entered WiFi account (SSID) and password are correct. Possible issues include case sensitivity errors, special character errors, etc.
¶ Step 4: Check for Router Anomalies
If other products can connect to the same router normally, it might be an anomaly in the router causing the current device not to join.
You can try restarting the router or contacting the router manufacturer for further support.
¶ 2-3. When Already Connected and Able to Connect to the "Anycubic" but is Unstable or Unable to Reconnect to the Network After Disconnection:
¶ Troubleshooting:
¶ Step 1: Check WiFi Antenna Contact
Ensure that the device's WiFi antenna is well-connected. Check if the antenna is loose or broken and ensure proper antenna contact. Poor antenna contact may sometimes be related to unstable connections.
¶ Step 2: Check WiFi Signal Strength
On the main interface, click the "Settings" icon, then click "Cloud Platform," and select the corresponding WiFi signal source to view the signal strength.

Typically, signal strength in the range of -40dBm to -80dBm is quite common and falls under the normal signal strength level.
When the signal strength is less than -80dBm, the signal is relatively weak. To optimize the connection,
it is recommended to place the device as close to the router as possible to reduce the likelihood of signal penetration through walls or interference from other objects.
We strongly recommend placing the device in a location close to the router to improve signal quality.
¶ Step 3: Check the Stability of the Home Network
It could be an issue with the home network itself causing instability.
Check if other devices also experience similar issues.
If so, try optimizing the home network, which may involve restarting the router or contacting the internet service provider for a resolution.
¶ How to Export Device Logs:
Note: The function to export device logs is available after version 3.0.3. Please ensure that the device is updated to the latest firmware version.
Connect the device to the power supply and turn it on. Insert a USB drive into the device's USB port.
Note that the Kobra 2 series device base has three USB ports on the front, with the leftmost one being for the camera,
and the other two for USB drives. Be sure to insert the USB drive into the correct USB port for files.
On the main interface, click the "Settings" icon, select "More Settings," then click "Export Logs to U-disk" (confirm that the device version meets the requirements).
If you cannot find the "Export Logs to U-disk" option on the current interface, please look on the next page.
Click "Confirm" to export logs to the USB drive and then click "Confirm" to finish.
