sunday PDQs (Handheld) require a high-quality network connection for most operations. A fully updated and well-connected PDQ (Handheld) resolves most common issues.
1. First things first: Run the network diagnostic
On the PDQ (Handheld), go to Settings (the cogwheel icon in the top right corner of the home screen).
Press "Test Network".
Once the test is complete, take a photo if you need to contact sunday support.
If there’s an issue, change the configuration (as described in this article) and run the test again to check if the results improve.
Understanding the test results
Network: The name of the Wi-Fi network your PDQ (Handheld) is connected to at the time of the test. We recommend using a dedicated Wi-Fi network, rather than one open to customers or shared with many other devices.
Connection: A general rating of your connection quality. If it’s poor, try changing the setup (new network, signal booster, etc.).
Internet connection test: sunday checks whether the PDQ (Handheld) can access the internet (e.g. google.com).
Connection to sunday servers: The PDQ (Handheld) must not only be connected to the internet but also able to reach sunday’s servers. Firewalls or other settings might block access to required sites.
Wi-Fi / Mobile Data: Indicates which type of network your PDQ (Handheld) is using at the time of the test.
Signal strength: Even with good internet and server connection, a weak signal in certain areas—such as outdoor seating or upper floors—can cause issues. Consider installing signal boosters (devices that amplify the Wi-Fi signal to help it pass through walls and floors).
Speed test (server to terminal): The higher the number, the smoother the PDQ (Handheld) will operate. A Wi-Fi network using modern standards and a fibre-optic internet connection provides the best performance. Too many devices on the same network, weak signal strength, or a low-quality internet provider can significantly impact speed.
2. Possible Issues
Slow or unstable connection
Wi-Fi: Check for interference, restart the router, install signal boosters, or disconnect unused devices from the network.
4G: Enable 4G mode on the terminal if Wi-Fi is not working.
Connection drops
Test Ethernet cables.
Switch to 4G if needed.
Tables cannot be retrieved
Ensure both the POS and PDQ (Handheld) are connected to the internet.
Restart the terminal and check network settings.
If the PDQ (Handheld)'s IP address has changed, update it in your POS (for payments pushed from the till).
Proactive Maintenance
Regularly test your connection speed and critical equipment.
Keep your routers and PDQs (Handheld) updated with the latest firmware.
Monitor network stability using dedicated tools.
