SmartFill network connection issues

June 4, 2025

For 3G SmartFill units

  1. Check SIM is correctly in module. The SIM holder is a simple spring-loaded slot. Just push the SIM to remove or load.

  2. Check antenna is firmly affixed to module. Antenna must be firmly screwed in to connector on module.

  3. Does SIM have PIN requirement removed? Place the SIM into an appropriate mobile phone and turn on to check this. You can use the phone menu to change this setting.

  4. Is SIM a data SIM? Can it download a website from a phone? Check with your service provider for details on the SIM provided.

  5. Install menu/9-more/2-network – Is access point correct?

  6. If you change settings then reboot SmartFill to ensure that settings are kept. Menu/5-unit/3-restart.

For Wifi SmartFill units

  1. Install menu/9-more/2-network – Are SSID & password correct?

  2. How far away is the SmartFill from the wifi router? (More than 30m not acceptable)

  3. Are there any metal obstacles between SmartFill and router? This will seriously degrade operating range.

For Ethernet SmartFill units

  1. Install menu/9-more/2-network – check IP settings

  2. Dynamic? If not, what is IP & gateway?

  3. Check firewall.

  4. Debug menu/1-system/2-network – is server IP set?

At the unit, press and hold the key for a couple of seconds to bring up the network status.
