Here are the steps you can take to resolve recurring Wi-Fi disconnection issues on the Ionmax+ ED12 12L Smart Industrial Dehumidifier:


✅ 1. Check Wi-Fi Signal Strength & Placement

  • Ensure the dehumidifier is within good range of the Wi-Fi router.
  • Avoid obstacles (walls, metal objects) and interference from other wireless devices.
  • If possible, place the router closer or use a Wi-Fi extender.


✅ 2. Restart Devices

  • Power-cycle the dehumidifier and Wi-Fi router.
  • Sometimes a simple reboot can restore stable connectivity.  


✅ 3. Verify Network Settings

  • Confirm the network name (SSID) and password are correct.
  • Ensure you’re connecting to a 2.4 GHz network (many IoT devices do not support 5 GHz).
  • Disable special SSID characters if the device has trouble recognizing them.


✅ 4. Update Firmware/Software

  • Check if there’s a firmware update available for the Ionmax+ app or the dehumidifier itself.
  • Install the latest updates — these often fix connectivity bugs.


✅ 5. Reduce Network Congestion

  • Disconnect unused devices from the Wi-Fi.
  • Avoid heavy bandwidth usage (streaming, downloads) when trying to maintain a stable connection.


✅ 6. Reset Wi-Fi Settings on the Device

  • Delete the saved Wi-Fi profile from the dehumidifier.
  • Reconnect to the network from scratch using the correct SSID and password.


✅ 7. Check for Router Settings That Block Connections

  • Disable MAC filtering if enabled.
  • Ensure DHCP is on so the device can get an IP address.
  • Check router firewall settings that might block IoT device traffic.


✅ 8. Ensure Stable Power

  • Check that the dehumidifier is receiving consistent power; voltage fluctuations can cause resets and Wi-Fi drops.


✅ 9. Check for App-Specific Issues

  • Close and reopen the Ionmax+ app.
  • Log out and log in again.
  • Reinstall the app if needed.


✅ 10. Factory Reset (Last Resort)

  • If problems continue, perform a full factory reset on the dehumidifier and set up Wi-Fi again.


✅ 11. Contact Support
