Why Your ‘Slow Internet’ Might Not Be the Internet at All
You’ve heard the complaints. “The Wi-Fi is slow again.” “I can’t upload this file.” “The video call just froze… again.”
Naturally, the first place most businesses look is the internet provider. So when a growing business upgraded to a high-speed fibre connection to solve their lagging network, they expected everything to run smoothly. But during busy hours, the slowness returned, and frustration mounted.
The culprit? Cat 5 cables that couldn’t handle modern data demands.
Here’s the thing: your internet may be lightning-fast, but if your internal data cabling can’t keep up, it’s like driving a Ferrari on a gravel road.
Data cabling is the physical network of cables that connects all your devices, computers, servers, printers, phones, and wireless access points, allowing them to communicate and share information. These cables carry electrical or optical signals that transmit your data across the office network, from a simple email to large file transfers and video conferences.
In this guide, you’ll learn 12 clear signs that your business needs a data cabling upgrade, understand why this investment matters, and discover how to move forward with confidence.
Sign 1: Frequent Network Dropouts or Slow Speeds
If employees regularly complain about slow internet or dropped connections, your cabling might be the culprit. While it’s easy to blame your internet service provider, the problem often lies in aging or inadequate cables that can’t handle current data demands.
Network performance issues manifest in several ways: files take forever to upload to cloud storage, web pages load slowly despite fast business internet, or employees lose connection during important video calls. These problems typically worsen during busy periods when more people are using the network simultaneously.
Sign 2: Visible Wear, Damage, or Tangled Cabling
Take a look at your server room or network closet. If you see frayed cable jackets, bent connectors, or what technicians call “cable spaghetti”, an angled mess of wires, it’s time for a structured cabling upgrade.
Damaged cables don’t just look unprofessional; they create real performance problems. Bent pins in connectors can cause intermittent connections, while damaged cable jackets expose wires to interference and potential short circuits. Tangled cables make troubleshooting difficult and increase the risk of accidentally disconnecting the wrong cable during maintenance.
Professional structured cabling organises your network infrastructure with proper cable management, labelling, and documentation. This organisation pays dividends when you need to troubleshoot issues or expand your network.

Sign 3: Outdated Cable Standards (Still Using Cat 5)
If your business still relies on Cat 5 cables installed years ago, you’re running on outdated technology. Cat 5 cables support maximum speeds of 100 Mbps, adequate for basic internet browsing but insufficient for modern business applications.
Cat 6 cables support speeds up to 1 Gbps (1000 Mbps), while Cat 6a cables can handle 10 Gbps over longer distances. These newer standards also provide better protection against interference and crosstalk between cables.
The difference becomes obvious when transferring large files, backing up data to cloud storage, or running bandwidth-intensive applications. Upgrading from Cat 5 to Cat6 or Cat6a can reduce the file transfer times by 80%, allowing designers to work more efficiently with large image and video files.
Sign 4: Rising Employee Complaints About Connectivity
When IT tickets about connectivity issues start piling up, or employees regularly mention network problems in meetings, it’s a clear sign your infrastructure needs attention. These complaints often increase gradually, making them easy to dismiss as isolated incidents.
Pay attention to patterns: Are complaints more frequent during certain times of day? Do they spike when specific applications are used? Are certain areas of the office more affected than others? These patterns often point to cabling limitations rather than software or hardware issues.
Document these complaints to build a business case for infrastructure upgrades. The cost of lost productivity due to network problems often exceeds the investment required to upgrade your cabling.
Sign 5: Expanding Office Space or Adding New Devices
Business growth is exciting, but it puts additional strain on your IT infrastructure. Adding new employees, devices, or office locations increases your data load exponentially. Without adequate cabling to support this growth, your network becomes unstable and inefficient.
Planning your cabling upgrade alongside business expansion prevents these growing pains and ensures your network infrastructure can support future growth.
Sign 6: Recurring IT Troubleshooting & Higher Maintenance Costs
If your IT team spends increasing amounts of time troubleshooting network connectivity issues, outdated cabling could be the hidden culprit. These recurring problems create a cycle of temporary fixes that never address the root cause.
Calculate the true cost of these ongoing issues: IT staff time, employee downtime, and the opportunity cost of delays. Often, the annual cost of maintaining problematic cabling exceeds the one-time investment required for a comprehensive upgrade.
One retail company discovered that they were spending more on monthly IT troubleshooting than they would have spent on a complete cabling upgrade. After investing in new infrastructure, their IT support calls dropped by 70%.
Sign 7: Incompatibility with New Hardware or Cloud Solutions
Modern business equipment often requires higher bandwidth and lower latency than older cables can deliver. If new servers, VoIP systems, or cloud applications perform poorly despite meeting all other requirements, your cabling might be the bottleneck.
This incompatibility becomes particularly obvious when implementing new technologies like IP security cameras, wireless access points, or advanced networking equipment. These devices often require Power over Ethernet (PoE) capabilities that older cables can’t provide reliably.
Sign 8: Poor Video Conferencing Quality
Video conferencing has become essential for modern business operations. If your video calls suffer from lag, jitter, pixelation, or dropped connections, inadequate cabling often shares the blame with insufficient bandwidth.
Quality video conferencing requires consistent, low-latency connections. Old or damaged cables introduce packet loss and interference that make real-time communication difficult. This problem becomes more noticeable as businesses rely more heavily on video meetings for client interactions and remote collaboration.
Sign 9: Increased Use of Cloud Applications & VoIP
As businesses migrate to cloud-based software and Voice over Internet Protocol (VoIP) phone systems, they demand more from their network infrastructure. These applications require consistent, high-speed connections that older cabling standards struggle to provide.
Cloud applications need reliable upload speeds for real-time synchronisation, while VoIP requires low latency for clear voice quality. Legacy cabling creates bottlenecks that result in delayed file syncing, dropped calls, and poor voice quality that can affect customer relationships.
Sign 10: Lack of Compliance with Industry Standards
Many industries have specific requirements for network infrastructure and data handling. Outdated cabling can leave your business out of compliance with regulations like GDPR, HIPAA, or industry-specific standards.
Modern cabling standards include improved shielding and security features that help protect sensitive information during data transmission. Regular audits increasingly scrutinise network infrastructure as part of overall data security assessments.

Sign 11: Physical Limitations During Office Moves or Renovations
Office relocations or renovations often reveal the true state of your cabling infrastructure. If you discover that cables can’t be easily rerouted, extended, or organised during these projects, it’s a clear indication that your infrastructure needs modernisation.
Properly installed structured cabling systems are designed for flexibility and future modifications. If your current setup doesn’t allow for easy changes, you’re likely dealing with outdated installation practices that will continue to cause problems.
Sign 12: Overheating or Electrical Interference Issues
Old or poorly shielded cables can pick up interference from nearby equipment, affecting both performance and safety. This interference manifests as inconsistent network performance, especially near electrical equipment, fluorescent lights, or other sources of electromagnetic interference.
Overheating in network closets can indicate that cables are working harder than they should to maintain connections. Modern cables include better shielding and heat management features that improve both performance and safety.
The Risks of Ignoring Outdated Cabling
Postponing a cabling upgrade might look cost-effective at first, but the risks quickly outweigh any short-term savings:
- Higher risk of data loss – Unreliable connections can cause incomplete data transfers, lost work, or failed cloud syncs.
- System downtime – Customer-facing systems may go offline during business hours, harming your reputation and losing potential revenue.
- Security vulnerabilities – Older or damaged cables may not meet modern security standards, creating points where data can be intercepted or compromised.
- Reduced productivity – Network issues slow down daily tasks, cause frustration, and disrupt collaboration, leading to missed deadlines.
- Hidden operational costs – Frequent troubleshooting, delays, and reactive fixes create ongoing expenses that add up over time.
