Resolving connectivity issues

Smart Terminal (WisePOS E) connectivity

Address common technical problems caused by network connectivity issues with your Smart Terminal (WisePOS E) Lightspeed Payments terminal:

  1. Access Wi-Fi Settings in the terminal.
    • Navigate to Settings and select Wi-Fi Settings to check your network's status.
  2. Ensure the terminal and register are on the same network.
    • The terminal may switch to a different network after a power outage. This can affect its ability to communicate with the register.
    • It is recommended to have the terminal forget incorrect wifi networks. This prevents the terminal from automatically connecting to an incorrect network.
  3. Ensure the terminal's Wi-Fi signal is strong. If not, move closer to the router or remove any potential signal obstructions.
  4. Compare the IP addresses of the terminal and register.
    • Note the terminal’s IP address on your Smart Terminal (WisePOS E) and compare it with the IP address of your connected iPad or computer. Matching the first three numbers indicates they are on the same network. Example: and

    • Mac OS: Use the Apple menu > System Preferences > Network to find the IP address.
    • Windows: Go to Start > Settings > Network & Internet and use Properties to find the IP.
    • iPad: Check the IP in iOS Settings > Wi-Fi by tapping the information button.
  6. Connect devices to the correct network if IP addresses differ.

Updating your Smart Terminal (WisePOS E)

As terminal software updates are made available, your payment terminal updates automatically. 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 initiate when you turn the terminal back on. To manually check for an update, reboot the reader.
