POS Network Issues: Tips to Get Back Online Quickly

POS network issues can hit retailers hard. According to a Gartner study, businesses lose an average of $5,600 for every minute of unexpected downtime.

Both internal and external networks are required to keep a company running. These networks support your point of sale (POS), email, phones, and web-connected devices.

Therefore, network issues don’t just prevent you from processing credit card transactions; they also prevent ecommerce integration, CRM access for loyalty programs, inventory management data collection, and remote POS access.

So, what can business owners do to reduce the impact of POS connectivity and network issues?

First, if you are experiencing a network problem with your POS right now, start by diagnosing the source of the problem. Determine if it’s a network issue or a POS issue and then follow basic troubleshooting steps.

If you aren’t experiencing issues, there are steps you can take to prevent POS downtime or create a failover system to protect yourself. This guide walks you through all of these points, including tips for diagnosing a POS connectivity issue, troubleshooting problems, creating a failover system, and performing regular preventative maintenance on your POS network.

Common POS Network Errors

If your POS is not connecting to the Internet, the No. 1 cause is hardware failure;

Did you know that hardware failures are behind more than half of all IT downtime incidents? According to CommandLink, they account for about 53% of the cases – making them one of the biggest disruptors for systems like POS networks.

However, issues you face with your POS system can take many forms. Some of the most common types of network errors resulting in downtime include:

1. Spotty Connectivity – Your POS system’s internet connectivity will be sporadic. This can be caused by network congestion, faulty hardware, or software issues.

2. Complete Loss of Connection – If your POS is not connecting to the Internet, you will not be able to process any transactions. Common reasons the POS can’t get online include network outages, power outages, hardware failure, or incorrect network settings.

3. Slow Network Speed – If your POS can connect to the Internet, but the network speed is too slow, credit card processing can be delayed or transactions will time out. This is often caused by slow internet connection, congestion, or hardware issues.

4. Software Issues – Sometimes POS software can cause network issues. This can be caused by compatibility issues, configuration issues, or bugs in the software.

Ultimately, these issues can generally be remedied by building a strong network and conducting regular maintenance.

Pro Tip. When considering POS software solutions, be sure you explore how reliable a system is and if data loss prevention systems are available.

How POS Downtime Impacts Your Business

When your POS network goes down, it manages to cause mayhem to your entire operation. From sales to customer satisfaction, every part of your business feels it.

Direct Revenue Loss

Every minute your POS system is down, you’re losing potential revenue. Transactions stall, checkout lines grow, and customers walk away frustrated. Even short outages can lead to hundreds—or thousands—of dollars in lost sales, especially during peak hours.

Poor Customer Experience

Imagine a customer ready to pay, only to hear, “Sorry, our system isn’t working right now.” That’s a break in trust. When POS connectivity fails, shoppers often choose convenience elsewhere, and it’s not easy to win them back.

Operational Disruptions

When your POS is offline, your team can’t process returns, access product data, or check inventory. These interruptions slow down your employees and create confusion. Without access to key systems, simple tasks turn into time-consuming manual work.

Inventory and Data Inconsistencies

A POS network issue can lead to mismatched data. Sales not syncing, stock counts going off balance, and reports becoming unreliable. Without real-time updates, you risk overselling items you no longer have or missing low-stock alerts that keep your shelves full.

Brand Reputational Damage

Customers remember how a business handles a POS system failure. Frequent outages can make your brand look unprepared, no matter how great your products are. Reliability builds loyalty, and consistent downtime erodes that trust faster than any bad review.

Hidden Labor and Recovery Costs

Downtime eats into productivity. Staff spend hours troubleshooting, calling support, or processing transactions manually. Meanwhile, IT teams scramble to restore the POS server or trace the cause of failure, diverting time from higher-value work.

Customer Loyalty Decline

When customers repeatedly face checkout problems, they stop returning. Modern shoppers expect reliable experiences. Especially when they’re used to quick, cashless transactions. Persistent POS connectivity problems make your business seem outdated, and that perception can quietly push loyal buyers toward competitors.

Missed Competitive Advantages

Stable POS operations give you access to valuable data. What’s selling, who’s buying, and when. If your system keeps going offline, you lose those insights. Without them, forecasting trends or running personalized promotions becomes guesswork instead of strategy.

Step 1: Determine the Cause of the POS Connectivity Issue

If you’re currently experiencing a network failure, answer this question first: Is this a network issue or a POS issue?

Knowing this will help you troubleshoot the problem and know where to look to get your system back online. Here are some differences:

Network Issue

If you know the failure is due to an internet outage, then you can take measures to get back online. Some steps you can take:

• Restart your modem and router
• Contact your ISP
• Resetting your router

Ultimately, if it’s an internet issue, your Wi-Fi network will be down, and no devices will be able to connect to the Internet.

POS Failure

Alternatively, if you have confirmed that the internet connection is sound, but you’re experiencing a POS network failure, here’s what to do.

First, determine if all the POS terminals are affected or just one.

If only one terminal seems affected, you are likely dealing with a hardware issue. Check for a loose cable at the POS switch/router and also at the terminal itself. You may need to replace faulty hardware, but you’ll be able to continue to operate using other terminals.

If all terminals are affected and it’s not an internet outage, contact your POS provider. You are probably facing an issue with the POS server or the associated routed.

Another Option: POS Offline Mode

You can try to operate your POS in offline mode, which will keep you online and allow you to continue processing credit card transactions.

This is a feature of our FTx POS, our retail POS software solution. Offline mode is a temporary fix. In offline mode, you won’t be able to perform internet-supported verification processes (e.g., checking if funds are available). You’ll still want to get your POS connected to the Internet as quickly as possible.

Troubleshooting Network Connectivity Issues on POS

When a connectivity issue strikes, there are simple steps you can take to respond. Often, the issues are caused by simple-fix errors, e.g., a loose cable or a quick reset.

If you’ve determined the cause to be your network, troubleshoot your network devices (modem, router, etc.). If it’s POS-related, you can troubleshoot POS connections and devices. Here are some troubleshooting tips to follow:

1. Check Physical Connections – Ensure all cables are properly connected. This includes network cables, power cables, and any other cables connected to your POS system.

2. Check Wi-Fi Connections – If you’re using a wireless connection with your cloud POS, check that the Wi-Fi is turned on and that your POS terminal is within range.

3. Restart the POS System / Network Devices – A simple restart oftentimes can resolve connectivity issues. Turn off your POS and network devices (router or modem), wait about 1 minute, and then turn them back on.

4. Contact Your POS Provider – If these quick, simple fixes don’t work, contact your POS support team. A support team will protect you from data loss and can help diagnose and fix the problem faster.

5. Check Network Settings – Ensure that the network settings allow your POS to connect to the correct network. You’ll also want to check the internet protocol (IP), domain name system (DNS) server, and other network settings.

6. Check Firewall and Security Settings – Security software or a firewall may prevent the POS from connecting to the network. Check settings for these tools. Note: This can happen after a software update or system restarts.

7. Update Your Software – Running outmoded versions of software can disrupt your connection and result in downtime. Make sure you’re running the latest version of your POS software and that the firmware settings on network devices are up to date.

8. Test with a Backup Internet Connection. Switch over manually and confirm your failover system works as intended.

9. Check for Signal Interference. Devices, thick walls, or nearby networks can affect performance—adjust placement as needed.

10. Update Drivers. Regular updates for routers, modems, and terminals prevent unexpected network hiccups.

Best Practices to Prevent POS Network Issues

Keeping your POS network stable is more than essential. A few smart precautions can keep your business running smoothly even when technology falters.

Use Dual Internet Connections

A single internet connection leaves your business exposed. Consider a dual-connection setup—primary broadband backed by a cellular network. If one fails, the other keeps your POS system online, ensuring your checkout never stops moving.

Enable Automatic Failover Routing

Failover routing automatically switches your network to a backup connection the moment your main one drops. This small step eliminates downtime during outages and protects your POS system from going down at critical sales moments.

Separate POS Traffic from Guest Networks

Mixing your POS traffic with customer Wi-Fi is a common problem of point-of-sale system security. It slows down transactions and increases vulnerability. Keep POS devices on a dedicated, secure network to prevent congestion and reduce risks.

Encrypt Local Data and Backup Securely

Even with perfect uptime, security should never take a backseat. Encrypt sensitive data and back it up regularly—preferably in multiple secure locations. This practice protects you from data corruption, one of the leading causes of POS connectivity issues.

Integrate AI-Powered Predictive Monitoring

Modern systems can alert you before things go wrong. Predictive monitoring tools analyze your network POS performance and flag unusual activity early—slow speeds, packet loss, or device disconnections—so you can fix them before they become full-blown outages.

Pro Tip. These are just general steps, and they’re dependent on how your network and POS are set up. Contact Customer Support from your POS provider early in the process.

Preventative Steps for Reducing POS Network Issues

Neglecting regular system maintenance puts you at greater risk for downtime and network errors. If you’ve waited to update your smartphone operating system, and apps started crashing, you’ve experienced this effect firsthand.

Ultimately, there are several quick system maintenance tasks you can do to protect your POS system:

1. Physical checks – Check your POS system devices and network equipment for physical damage or wear-and-tear. Replace any damaged components (e.g., mouse-chewed cables are a common culprit).

2. Invest in a reliable ISP – Regularly conduct speed tests on your network. Upgrading your service or switching ISPs will reduce slow-speed or network-related risks.

3. Regular software updates – Run the latest version of your retail POS software, and regularly update network device firmware. Updates protect from bugs and include performance improvements.

4. Upgrade network equipment – High-quality equipment (routers, switches, and cables) costs more because it’s more reliable. Upgrade your system if possible.

5. Perform monitoring / backups – Monitoring your system is important for spotting issues before they arise (e.g. speeds starting to slow or sporadic connectivity). You should also backup your POS data regularly.

6. Employee training – You and your employees should understand what to do when a POS system fails. Every preventative plan should include training to ensure your employees know what to do.

In addition to these measures, you should also consider developing a POS failover system. This is a complete, wired secondary system that your POS switches to when your primary system fails.

Setting Up a Failover POS Network

The best failsafe is having an alternative system in place already as a backup. In terms of POS systems, a failover is a backup POS that kicks into place as soon as the primary network fails.

This is one of the best solutions that will reduce your need for data recovery following an outage.

Often, these systems might be completely mobile and automatically connect to a 5G or LTE network. Therefore, in the case of an outage, these systems support a backup operational mode that supports all system functions, such as processors, servers, networks, and databases. You might have heard of this referred to as “redundancy.”

Failover Network for Your POS: Key Features

When looking at failover systems that will prevent POS data loss, you should find a solution that retrofits your existing infrastructure for cellular network access. Here are four key features to look for:

1. Simplified Integration – Choose a network failover solution that calls that can be easily located and mounted where cellular reception is the strongest.

2. Certified Connectivity Options – Your failover system should come with cellular extenders that support multiple carriers and also multiple WAN connectivity options such as Ethernet or cellular. By including load balancing and failover capabilities, your backup system should offer 5G LTE.

3. Upgradeable with 5G LTE Plug-In Modems & Dual Sim Support – No matter the size of your business or the amount of transactions at your store, you need network failover that can handle supporting the breadth of your data, which means you need the best, fastest technology, i.e., 5G.

4. Centralized Device Management – Choose a failover that offers a centralized management platform. You need easy setup, configuration, and support, so look for a solution provider that can assist you before, during, and after deployment.

Power outages and network connectivity issues will happen. A failover in place at your retail store so that you can access your network and process credit and debit cards during the outage. Consider this statistic: According to CloudControl, 96% of businesses with a disaster recovery solution in place are able to fully get their operations back on track.
