Shopify POS Go: QoS Settings Diagnostic Report - Solar... | terminalfaults.org

Technical Background:

QoS relies on packet prioritization based on ToS/DSCP fields in IP headers. This requires the Shopify POS Go to have configurable software settings to tag packets and the network infrastructure (router/switch) to honour these tags. Insufficient bandwidth or misconfigured network devices can negate any QoS settings on the POS Go. DHCP option 43 or 60 can be used to provision QoS configurations, but requires software support on the POS Go.

Symptoms:

Reported inability to configure or verify Quality of Service (QoS) settings on the Shopify POS Go device, leading to inconsistent network performance for transactions.

Possible Causes:

1. Lack of QoS configuration options within the Shopify POS Go operating system.
2. The network router or switch does not support or is not configured to prioritize traffic based on QoS settings.
3. Insufficient network bandwidth, rendering QoS ineffective.
4. Incorrect network configuration preventing the POS Go from communicating with the network using QoS.
5. Outdated firmware on the POS Go or network equipment lacking QoS support.
6. Interference from other network devices or applications consuming excessive bandwidth.

Solution:

1

Verify the Shopify POS Go software version and check the Shopify help documentation for QoS settings.
2

Examine the network router/switch configuration to confirm QoS is enabled and configured correctly for the POS Go's traffic.
3

Use a network analyzer (e.g., Wireshark on a connected computer) to check if the POS Go is tagging network packets with the appropriate QoS markings.
4

Contact Shopify support to inquire about the availability of QoS settings or potential software updates that might enable QoS functionality.
5

Assess network bandwidth utilization to ensure sufficient capacity for prioritized traffic. Upgrade internet plan if needed.
6

Reduce network congestion by limiting non-essential network activities during peak transaction times.
7

If the router supports it, assign a static IP address to the POS Go and prioritize traffic based on that IP.

Safety Warning:

Handle the Shopify POS Go with care to avoid damage to the screen or internal components. Do not attempt to open the device. Ensure proper cable management to prevent tripping hazards and strain on the power cable. Safe Handling: Unplug the device from the power source before performing any external maintenance.

Prevention:

Regularly update the Shopify POS Go software and network equipment firmware. Monitor network bandwidth usage. Ensure the network infrastructure is configured for optimal performance. Conduct routine network assessments.

Expert Tip:

Check the router's QoS settings for application-specific prioritization. If 'Shopify POS' or similar is an option, prioritize it. If not, prioritize based on the POS Go's IP address or MAC address. A ferrite choke placed on the POS Go's power cable may mitigate some EMI.

Frequently Asked Questions

•What version of the Shopify POS Go software is currently installed?

Check the device's settings menu under 'About'.

•What is the model and firmware version of the network router/switch?

Log into the router's admin interface to find this information.

•Is there other network congestion occurring during peak transaction times?

Use a network monitoring tool to assess bandwidth utilization.
