When laptops and other devices on your business network start running slowly, the issue is often linked to how your network is configured and managed. Network settings control how data flows between devices and the internet, so if these settings are inefficient or outdated, it can cause delays, interruptions, and frustration for your staff.
Slow devices impact more than just daily convenience. They reduce staff productivity, increase downtime, and can even heighten cyber risks if security settings are neglected. For example, poor network segmentation or outdated firmware can expose sensitive data to unauthorised access, conflicting with UK GDPR and Data Protection Act 2018 requirements. Additionally, slow performance can erode customer trust if your team cannot respond promptly or systems fail during critical operations.
Real-world example
Consider a UK-based SME with around 50 employees using a mix of laptops and desktops connected via Wi-Fi and wired networks. The business noticed frequent slowdowns during peak hours, affecting email, cloud applications, and file sharing. Their managed IT provider discovered that the Wi-Fi access points were overcrowded and set to default channels, causing interference. Network switches were not prioritising critical business traffic, and firmware updates were overdue. After adjusting channel settings, implementing Quality of Service (QoS) rules to prioritise key applications, and scheduling regular firmware updates, the network performance improved significantly, reducing staff complaints and supporting compliance with Cyber Essentials Plus by ensuring devices were properly maintained.
Network settings checklist for improving device speed
- Check Wi-Fi channel congestion: Use simple tools or ask your IT provider to scan for crowded channels and switch to less busy ones to reduce interference.
- Enable Quality of Service (QoS): Prioritise business-critical applications like email, VoIP, and cloud services to ensure they get bandwidth preference over less important traffic.
- Update firmware regularly: Keep routers, switches, and access points up to date to fix bugs and improve performance and security.
- Segment your network: Separate guest Wi-Fi from internal business devices to reduce congestion and improve security.
- Review IP address allocation: Ensure devices have correct and non-conflicting IP addresses, ideally via DHCP with reserved addresses for key devices.
- Monitor bandwidth usage: Identify devices or applications consuming excessive bandwidth and manage or restrict them as needed.
- Ask your IT provider: How do they monitor network health and performance? What tools do they use to detect and resolve bottlenecks?
- Audit access controls: Confirm that only authorised devices connect to your network, supporting compliance with ICO guidance and Cyber Essentials.
Next steps
Improving network settings is a practical way to enhance device speed and overall IT reliability. If slow laptops or devices are affecting your business, speak with a trusted managed IT provider or IT advisor who can assess your current network setup, recommend targeted changes, and help maintain ongoing performance and security. Regular reviews and proactive management are key to avoiding downtime and supporting compliance with UK data protection and cybersecurity standards.
