To troubleshoot Lightspeed Payments, use the following common scenarios to help diagnose the issue:

Check connectivity

To check connectivity go to settings, then select Wi-Fi settings. This will display all available Wi-Fi networks. To see more details about the connection, tap on the connected network name.

  • Make sure the network is connected and has internet access.
  • The signal strength is good.
  • The device has an IP address assigned.
  • The subnet matches the one that your application is connected to.

Updating issues

If you terminal does not update, itʼs possible that it cannot connect to Lightspeed Payments.

As terminal software updates are made available, update your terminal to the latest available version to continue using Lightspeed Payments. Failing to install a required update can prevent a terminal from accepting payments.

Leave your terminal on and connected to power to receive automatic software updates. This ensures that updates happen at midnight (in the timezone of the assigned location) to avoid interruption to sales.

If you unplug the terminal at night, an update could start when you turn it back on. To manually check for an update, reboot the reader.
