This article covers the essential aspects of setting up your network for optimal use with Lightspeed Restaurant. We’ll discuss recommended hardware, network setup, and how Lightspeed communicates within your network. Understanding these elements will help you create a stable and efficient environment for your Lightspeed system.
Choosing the right hardware
Optimizing your network’s performance begins with your hardware. This includes network hardware, such as routers, but also POS hardware, such as printers. Here are some considerations to make during the hardware purchasing phase.
- Purchase your network hardware directly from Lightspeed if possible. Our Support team receives training for supported networking products that we can remotely access.
- Use a dedicated router for your Lightspeed POS devices, printers, and payment terminals to avoid interference with other internet-connected hardware (for example, security cameras).
- We recommend purchasing network hardware made by UniFi or IgniteNet.
- LAN-based receipt and kitchen printers are the most reliable due to their hardwired connection to your network.
- Avoid using Wi-Fi or Bluetooth printers in a kitchen or other environment containing interference-causing devices (for example, electric motors or cordless phones) or large physical barriers (for example, large metal appliances).
Consider purchasing a payment terminal with 4G capability. If your main internet goes offline, you’ll be able to process standalone payments via the cellular connection.
Setting up your network
This section explores best practices for the setup and configuration of your network for use with Lightspeed Restaurant. Physical setup focuses on hardware placement and connections, while network configuration involves setting up protocols for secure and efficient communication.
If you don’t know how altering the physical setup of your network will affect it, consult an IT professional before making changes. Lightspeed Support cannot troubleshoot or assist with network hardware purchased outside of Lightspeed
Set up your router in an open, central, elevated area. This area should be:
|Internet speed||POS devices must have a minimum connection speed of 512 Kbps. Perform a speed test from each device to verify this.|
Test Wi-Fi coverage on each POS device at peak times to ensure signal strength stays between -67dBm and -30dBm when at full customer capacity. For roaming POS devices, ensure there is sufficient coverage in every part of the restaurant. You do not need to test POS devices that are connected via Ethernet.
If necessary, add additional access points to your network or move existing ones to increase signal coverage and connection reliability for all devices.
|iOS / iPadOS settings||
Configure the network settings on each iOS or iPadOS device to our recommended standards. This can help prevent potential disruption to certain POS functions.

|Firewall||Configure your firewall to allow open communication between your devices and Lightspeed. For more detailed guidance, continue reading.|
|Ports||Open networks ports 22, 80, 443, 7373, 8080, 8883, 9140, 8443, 9100, and 9880 to allow devices and hardware to communicate with each other and with Lightspeed’s cloud servers.|
Whitelist network traffic to and from:
|IP addresses||There are no specific IP addresses you need to whitelist.|
|Features to disable||Turn off wireless isolation, access point isolation, client isolation, or any other features that limit the ability of devices on your network to communicate with each other.|
Understanding network communication
This section discusses how the Lightspeed network works, including the different types of POS devices and how data moves around. This will help you understand the network activity caused by Lightspeed, which can be useful for managing your system.
Role of active and passive POS devices
Active and passive POS devices serve crucial roles within your network. They operate on OSI Layer 2, which ensures reliable device-to-gateway and device-to-device communication in unicast or broadcast mode.
- Active POS devices function as local servers, store financial transactions, keep track of open orders, and transmit data to the Back Office.
- Typically only one active POS device is recommended. For optimal performance, connect this device directly to your router using an Ethernet adapter.
- Before adding more active POS devices, try improving the connection of your existing active device by using Ethernet or moving it closer to the router. One active device with a strong connection will outperform multiple active devices with weaker connections.
- Active POS devices must remain connected to your network and powered on with the Lightspeed app open during service. If an active device disconnects, other devices running the Restaurant POS app won't be able to function properly.
- Passive POS devices relay data to an active device, which then sends it to the Back Office.
- Use passive devices for any POS devices in your restaurant after your initial active device, especially those that may frequently turn off or disconnect from your network.
- Passive devices must be connected to the same network as an active device with the Restaurant POS app open.
Flow of data to and from POS devices
Active POS devices communicate with:
Active POS devices transmit encrypted blocks of financial data to the Back Office, providing a detailed record of transactions.
Active POS devices receive sales data and other information from passive devices. The active device then processes the data and sends it to the Back Office.
Active devices send technical data such as logs, crash reports, and error messages to our servers. This data is used to optimize performance and troubleshoot issues.
Active devices send and receive data to and from Lightspeed Payments payment terminals to facilitate card payments and refunds. A POS device signals the payment terminal to initiate a transaction, then the terminal communicates with Lightspeed Payments to obtain approval. Active devices also receive error messages from payment terminals when issues arise.
Active devices send print commands to connected printers and receive error messages if printing fails, ensuring receipt and ticket generation.
Active devices can interact with third-party software through API, both sending data to and receiving data from these programs. This enables additional features such as inventory management and customer relationship management.
Active devices communicate with Apple's servers to receive software updates.
Passive POS devices communicate with:
Passive devices relay information to active devices, which then process the data and send it to the Back Office. They depend on active devices to act as intermediaries for information flow.
Passive devices send and receive data to and from Lightspeed Payments payment terminals to facilitate card payments and and refunds. A POS device signals the payment terminal to initiate a transaction, then the terminal communicates with Lightspeed Payments to obtain approval. Active devices also receive error messages from payment terminals when issues arise.
Passive devices send print commands to connected printers via active devices and receive error messages if printing fails. This ensures proper generation of receipts and tickets, even from non-active devices.
Passive devices communicate with Apple's servers to receive software updates.
