8. Troubleshooting

If you encounter issues with your Foxconn T99W175 DW5930e module, consider the following troubleshooting steps:

• Module Not Detected:
  • Verify that the module is correctly seated in the M.2 slot.
  • Ensure the M.2 slot supports WWAN modules and PCIE mode.
  • Check your device's BIOS/UEFI settings to ensure the WWAN module is enabled.
  • Confirm that the correct drivers are installed.
• No Network Connection:
  • Ensure a valid and active 5G-enabled SIM card is inserted correctly.
  • Verify that the antenna cables are securely connected to the module.
  • Check your operating system's network settings for correct APN configuration.
  • Confirm that mobile data is enabled in your OS settings.
  • Test the SIM card in another compatible device to rule out carrier issues.
• Slow or Unstable Connection:
  • Check the signal strength indicator. Weak signal can lead to slow speeds.
  • Move to an area with better network coverage.
