Why Reliable POS Network Connectivity Matters
A stable and responsive POS system is essential for smooth restaurant operations. Cambodia’s hot, humid climate—combined with occasional power cuts, unstable Wi-Fi, and high temperatures—can easily disrupt your POS system and daily operations.
Whether you’re running a café in Phnom Penh or a hotel restaurant in Siem Reap, understanding how to identify and solve common network problems will help reduce downtime and keep your customers happy.
1. Identify the Type of Network Problem
Not all POS network issues are the same. The first step is to understand where the problem lies. Is it:
- 🧭 A local network issue (LAN/Wi-Fi)?
- 🔌 A power-related issue affecting routers or POS terminals?
- 🌐 An internet outage affecting online services (cloud backup, remote access)?
- ⚙️ A software configuration issue?
By identifying the root cause, you can apply the right fix without unnecessary delays.
2. Use Wired Connections Where Possible
In humid or high-traffic environments, wireless routers can be unstable. We always recommend:
- Using LAN (Ethernet) connections for main POS stations and kitchen printers
- Reserving Wi-Fi for mobile tablets or customer devices
- Keeping cables protected and off the floor to avoid wear and corrosion
A wired connection ensures that your core POS functions like order taking and printing remain stable, even during poor Wi-Fi performance.
3. Invest in Surge Protection and Battery Backup (UPS)
Power instability is common in many parts of Cambodia, especially during rainy season. Voltage fluctuations can damage routers and POS terminals. Protect your hardware with:
- Surge protectors for all network equipment
- Uninterruptible Power Supplies (UPS) to keep your POS system running during brief outages
- Regular equipment checks to replace aging or overheated routers
4. Monitor Humidity and Heat
Humidity can cause network equipment to overheat or fail prematurely. We recommend:
- Placing routers and switches in cool, ventilated areas away from kitchens
- Using moisture-resistant enclosures if your hardware is installed near cooking areas
- Performing regular maintenance and cleaning of network ports and fans
5. Set Static IP Addresses for POS Devices
Many POS issues stem from devices losing connection due to changing IP addresses. To prevent this:
- Assign static IPs to your POS terminals, printers, and KDS screens
- Label each device and its IP for easy reference
- Avoid changing routers without first backing up your network settings
This small step can eliminate random disconnects between devices and printers.
6. Isolate POS Traffic from Guest Wi-Fi and Third-Party Interference
A common mistake we see in Cambodian hospitality venues is running the POS system on the same Wi-Fi network as customer devices or staff phones. This setup can cause congestion, packet loss, or printer delays—especially during busy service times.
To prevent this:
- Create a dedicated network (or VLAN) exclusively for your POS system
- Use a separate SSID and password not shared with guests or general staff
- Ensure POS devices connect to the router via LAN wherever possible
This gives your POS system a clean, stable channel to operate on—unaffected by streaming, downloads, or other internet usage.
📌 Important Note: Your POS system may still need to connect to the internet for cloud backups, online orders, or remote support—but this should be done through a securely routed connection that doesn’t compromise the POS network’s internal stability.
Additionally, we’ve seen many issues caused by internet providers or technicians making changes to the POS network while troubleshooting unrelated connectivity problems. This can lead to disconnected printers, broken IP assignments, or SambaPOS services going offline unexpectedly.
At POSFlow Solutions, we configure your POS network for maximum performance and reliability. Any updates to this network should be handled by our technicians—not by third-party providers—so we can ensure:
- Static IPs are preserved
- Printer and kitchen display routes stay intact
- SambaPOS services remain uninterrupted
If your internet provider needs to resolve Wi-Fi or connectivity issues, that can be done independently of your POS network setup.
7. Use SambaPOS Offline Capabilities to Stay Operational
With SambaPOS, your core POS operations continue even if the internet goes down. Orders, bills, and kitchen prints will still work because the system stores data locally on your POS server.
Cloud services like backups and reporting will resume automatically once connectivity returns.
8. Know When to Call Support
Sometimes the problem is deeper than a cable or setting. At POSFlow Solutions, we offer remote troubleshooting and network setup services as part of our monthly support package.
If your team is unsure, it’s better to get expert help to avoid causing bigger issues—especially during service hours.
