TABLE OF CONTENTS:
Modern businesses rely heavily on seamless connectivity to drive operations, enhance productivity, and deliver exceptional customer experiences. However, traditional networks often fail to meet the demands of today’s dynamic environments. Common network performance issues, such as latency, poor connectivity, and inconsistent performance, disrupt workflows, hinder cloud-based applications, and increase operational costs. Network outages and performance bottlenecks further aggravate these challenges, impacting both business continuity and user satisfaction.
Software-Defined Wide Area Network (SD-WAN) has emerged as a revolutionary solution to address these persistent challenges. By leveraging intelligent traffic management, enhanced visibility, and built-in security, SD-WAN empowers businesses to overcome common network connectivity issues and optimise performance across multiple locations. It simplifies network management while ensuring resilience, cost-efficiency, and adaptability for modern enterprise needs.
This blog explores the top 10 common network issues businesses face and demonstrates how SD-WAN provides effective solutions to these challenges, enabling organisations to transform their networks for enhanced reliability and performance.
Reliable networks are critical for supporting modern business operations, but many organisations struggle with recurring issues that disrupt workflows and affect productivity. Below, we detail the most common network issues businesses face, explaining their causes, impacts, and examples.
Network latency, a key factor in network quality problems, refers to the time it takes for data to travel from the source to the destination and back. This delay, often measured in milliseconds, can significantly impact real-time applications like video conferencing, financial trading platforms, and online gaming. Latency is not a single issue, but a collection of common network performance issues influenced by various factors.
Causes:
Impact: High latency can frustrate users, especially when using collaboration tools like Microsoft Teams or Zoom. For example, a global enterprise could face severe delays during client presentations due to latency issues in accessing cloud-hosted files, affecting client satisfaction.
Connectivity issues occur when devices or users cannot access network resources due to disruptions.
Causes:
Impact: Connectivity disruptions halt communication, delay workflows, and often lead to financial losses. For instance, a retail chain might experience a significant drop in online sales due to connectivity issues that made their e-commerce platform inaccessible for hours.
Bandwidth bottlenecks occur when network demand exceeds available bandwidth, causing slowdowns and congestion. This results in slower data transfer rates, increased latency, and poor network performance.
Causes:
Impact: Bandwidth bottlenecks severely reduce network performance and slow down critical applications. For example, an architecture firm using cloud-based rendering software might face significant delays in delivering projects due to insufficient bandwidth during peak hours.
Routing issues occur when data takes inefficient paths through the network, often caused by suboptimal configurations.
Causes:
Impact: Slow application responses and increased latency are common results. For example, a logistics company may face delays in processing customer orders due to poor routing that increases the time needed to retrieve data from cloud-hosted ERP systems.
Cybersecurity attacks occur when unauthorised entities gain access to the network, compromising data integrity and confidentiality. These vulnerabilities expose networks to risks such as data breaches, downtime, and compromised business operations.
Causes:
Impact: Security breaches result in downtime, reputational damage, and financial penalties. For instance, a healthcare provider may fall victim to ransomware, paralysing their network for days and delaying critical patient services.
Application performance issues occur when critical software runs slowly or fails to respond. It occurs when critical software, such as cloud-based applications, collaboration tools, or enterprise resource planning (ERP) systems, runs slowly or becomes unresponsive, significantly impacting productivity and user satisfaction.
Causes:
Impact: Degraded performance hampers productivity. For example, an e-learning platform could suffer because the students face disruptions due to frequent interruptions during live online classes or exams caused by application traffic being deprioritised.
Packet loss and jitter are common network performance issues that degrade the quality of data transmission, particularly in real-time applications such as VoIP calls, video conferencing, and online gaming.
Packet loss occurs when data packets travelling across a network fail to reach their intended destination. Jitter refers to the variation in packet delivery times, caused by inconsistent network performance. When packets do not arrive in the correct sequence or experience delays, it results in distorted audio or video quality, especially noticeable in time-sensitive applications.
Causes:
Impact: These issues often lead to distorted audio during VoIP calls or choppy visuals in video conferencing. In the past, several companies have reported frequent miscommunication during client meetings due to packet loss on their corporate network.
A lack of network visibility and monitoring is a significant challenge for IT teams relying on traditional WANs. Without centralised tools to track network performance and identify bottlenecks, organisations often operate reactively, addressing issues only after they disrupt operations. This approach increases downtime and complicates troubleshooting, particularly in large, distributed networks.
Causes:
Impact: Without visibility, identifying and resolving problems becomes reactive and time-consuming. For example, an IT service company may experience delayed resolutions to frequent outages due to a lack of real-time analytics.

Integrating new technologies with existing legacy infrastructure is a common hurdle for organisations undergoing digital transformation. Legacy systems are often outdated and lack the flexibility needed to accommodate modern network solutions, making the integration process both complex and error prone. These challenges can disrupt operations and lead to inefficiencies, especially in hybrid or multi-cloud environments.
Complexities:
Impact: Hybrid networks often experience disruptions during the integration phase. For example, a manufacturing firm transitioning to a hybrid cloud environment could suffer and face reduced production efficiency due to conflicts between legacy systems and cloud platforms.
Frequent network downtime is one of the most critical issues businesses face, as it directly impacts productivity, revenue, and customer trust. Downtime occurs when the network becomes entirely unavailable, halting all dependent activities and creating a cascade of operational challenges.
Causes:
Impact: The cost of downtime can be staggering, with some industries reporting losses of thousands of dollars per minute. For instance, a financial services firm estimated losing over £50,000 in revenue during a three-hour outage caused by an overloaded network switch.
These common network issues highlight the urgent need for modern solutions that proactively address these challenges. In the next section, we’ll explore how SD-WAN technology provides effective resolutions to these problems, helping businesses achieve reliable and high-performing networks.
