How to correctly configure your network for Mews POS

Mews POS

To use Mews POS effectively, you configure your network during system setup at your property. Mews POS is a cloud-based point-of-sale system that includes a web application for back-office tasks and an Android application for on-site order handling. Each device connects directly to the cloud and requires a stable internet connection. Mews POS does not support offline mode. A correct network configuration ensures device communication, maintains performance, and reduces connectivity issues in both wired and wireless environments.

 

In this article you can learn the following steps to configure your network to Mews POS:

 

Step 1: Create a dedicated network segment

Set up a separate network segment for Mews POS.

  • Use a subnet of 255.255.255.0
  • Separate it from guest Wi-Fi and the main administrative network

Note: A separate network segment helps isolate traffic and improve reliability.

 

 

Step 2: Provide reliable internet access

  • Ensure a guaranteed internet bandwidth of 10–20 Mbps download with 5 Mbps upload for the dedicated POS network segment
  • Prioritize Point of Sale traffic using Quality of Service rules on the router

 

Step 3: Configure network settings

  1. Enable DHCP for automatic addressing.
  2. Set DNS to Cloudflare’s (1.1.1.1 and 1.0.0.1) or Google’s (8.8.8.8 and 8.8.4.4) public DNS service.
  3. Configure DHCP reservations in your router for printers. This ensures they always receive the same IP address without manual device configuration.

 

Step 4: Adjust firewall settings and rules

Note: Mews transitions to new cloud hosting on 24th February 2026. To prevent service disruption, review your network setup with your IT team.

Allow outbound internet access on ports 80 and 443.

If your network setup restricts access, ensure it covers the following URLs and IP addresses:

  • Main server URL: pos.mews.com
  • Destination IP addresses – before the transition:
    • 75.2.54.226
    • 99.83.158.192
  • Destination IP addresses – after the transition on 24th February 2026:
    • Whitelisting is no longer recommended in this direction.
    • A complete list of IP ranges is available at IP Ranges | Cloudflare.

If your setup requires on-premise PMS submissions:

  • Source IP addresses – before the transition:
    • 52.209.124.16
    • 34.251.40.50
    • 34.241.171.234
  • Source IP addresses – after the transition on 24th February 2026:
    • 4.184.103.73
    • 4.184.103.103
    • 4.184.103.135

 

Step 5: Set up the wireless network

  1. Create a dedicated SSID for Point of Sale devices
  2. Use the 5 GHz frequency band
  3. Ensure signal strength is greater than –65 dBm across all service areas
  4. Place wireless devices on the same network segment as wired devices
  5. For on-premise PMS integrations, disable client isolation to allow direct communication between wireless devices

Note: Disabling intra-BSS blocking is critical for communication between Point of Sale tablets and payment terminals.

 

Step 6: Install wireless access points

  • Mount access points on ceilings in central locations
  • Overlap access point coverage to avoid dead zones
  • Enable roaming to support uninterrupted device movement
  • Conduct a professional site survey to verify optimal placement

 

Step 7: Set up the wired network

Use wired connections for fixed-location devices such as printers.

  • Connect Point of Sale devices to dedicated Ethernet ports
  • Label all Point of Sale ports clearly
  • Ensure all ports belong to the same network segment as the wireless devices

 

Step 8: Enable wireless-to-wired communication

Configure your network to allow seamless communication between wireless and wired devices.

  1. Unified network (required): Ensure all tablets, printers, and payment terminals are on the same subnet (for example, 192.168.10.x).
  2. Disable isolation: Disable Client Isolation, AP Isolation, or Guest Mode to allow local device communication.

 

Step 9: Avoid common network issues

  • Keep wireless and wired devices on the same network
  • Disable client and access point isolation
  • Allow discovery protocols such as Bonjour and mDNS through the firewall

 

Step 10: Complete the POS pre-installation checklist for your network

  1. Confirm internet bandwidth meets requirements
  2. Define and document the static IP address range
  3. Set up the dedicated network segment
  4. Enable and test DHCP
  5. Install wireless access points
  6. Enable Wi-Fi roaming support
  7. Check signal strength in all areas
  8. Disable Client Isolation
  9. Label Ethernet ports for Point of Sale use
  10. Test wireless and wired device communication
  11. Document the full network setup for onboarding

 

Step 11: Review checklist

  • Strong wireless coverage across all service areas
  • Consistent communication between tablets, printers, and payment terminals
  • No unnecessary device isolation
  • All configuration details shared with the Mews onboarding team
  • All communication paths tested before going live

This completes your network configuration for Mews POS. Monitor and maintain your network regularly.
