Wireless Device Configuration#

WiFi Configuration#

On the Ubuntu desktop, click the network icon in the upper-right corner. Select the WiFi network, enter the password in the dialog, and click Connect.

WiFi Troubleshooting#

Issue 1: The wireless network driver is not detected after the WiFi module is installed.#

Check 1: Check the Hardware#

Step 1: Confirm that the WiFi model is supported by MIIVII.#

Find the supported models in the user manual. AD10 example: https://doc.miivii.com/Apex-AD10-User-Manual-CH/wiki/Apex-AD10-WIFI.html.

  • If the model is not supported by MIIVII, replace it with a supported WiFi module.

  • If the model is supported by MIIVII, continue to Step 2.

Step 2: Confirm that the WiFi module is seated correctly in the PCIe slot.#

  1. Run ifconfig -a to check whether the WiFi interface is detected.

  1. sudo lspci

  • If the module does not appear, the hardware connection may be faulty or the module may be damaged. Check the module and its hardware connections.

Check 2: Check Service Status#

Step 1: Check the NetworkManager.service status.#

Open a terminal and run: sudo systemctl status NetworkManager.service

  • Reflash the image to determine whether the system environment is causing the issue.

Check 3:  Flash the Image Again to Check for a Software Environment Issue#

Step 1: Flash the Image#

Image flashing instructions: https://wiki.miivii.com/pages/viewpage.action?pageId=182034027.

After flashing the image, check whether the WiFi connection works.

  • If WiFi communication works after reflashing, the issue is caused by the system software environment. The customer must investigate that environment.

  • If the WiFi connection still fails after reflashing, continue to Step 2.

Step 2: Collect Logs#

Connect the device to the Internet, open a terminal, and enter:

curl -sSL https://doc.miivii.com/scripts/run_miivii_diagnostic.sh | bash -s wifi

Export the logs and the files under /var/log, upload them to the support ticket, and submit them to MiiVii Technical Support.

Issue 2: The device cannot connect to the network after the WiFi module is installed.#

Check 1: Check the Hardware#

Step 1: Confirm that the WiFi model is supported by MIIVII.#

Find the supported models in the user manual. AD10 example: https://doc.miivii.com/Apex-AD10-User-Manual-CH/wiki/Apex-AD10-WIFI.html.

  • If the model is not supported by MIIVII, replace it with a supported WiFi module.

  • If the model is supported by MIIVII, continue to Step 2.

Step 2: Confirm that the WiFi module is seated correctly in the PCIe slot.#

  1. Run ifconfig -a to check whether the WiFi interface is detected.

  1. sudo lspci

  • If the module does not appear, the hardware connection may be faulty or the module may be damaged. Check the module and its hardware connections.

Step 3: Check the Antenna Connections#

Required accessories: IPEX-to-SMA antenna adapter cable ×2.

  • Check that the required number of antennas is installed.

  • Check that the antennas are connected correctly.

Check 2: Cross-test the Connection#

Step 1: Cross-test WiFi Operation#

Connect another WiFi-capable device to the same WiFi network and check whether the network works.

  • If the other device connects successfully, continue to Check Service Status.

  • If the other device also cannot use the WiFi network, investigate the WiFi module itself.

Check 3: Check Service Status#

Step 1: Check the NetworkManager.service status.#

Open a terminal and run: sudo systemctl status NetworkManager.service

  • If NetworkManager.service is not running, try restarting it manually: sudo systemctl restart NetworkManager.service

    • If the service still fails to start, upload the error information to the issue ticket system for MIIVII analysis.

    • If the service starts after a manual restart, investigate why it did not start automatically.

Step 2: Check the wpa_supplicant.service status.#

Open a terminal and run: sudo systemctl status wpa_supplicant.service

  • If wpa_supplicant.service is not running, try restarting it manually: sudo systemctl restart wpa_supplicant.service

    • If the service still fails to start, upload the error information to the issue ticket system for MIIVII analysis.

    • If the service starts after a manual restart, investigate why it did not start automatically.

Check 4: Flash the Image Again to Check for a Software Environment Issue#

Step 1: Flash the Image#
