When setting up office computers, a common question is whether to connect them using wired Ethernet cables or rely on wireless (Wi-Fi) networks. Both options allow devices to access the internet and internal resources, but they differ in speed, reliability, security, and how they impact day-to-day business operations.
Why connection type matters for your business
Choosing between wired and wireless connections affects your business's productivity and security. Wired connections generally offer faster, more stable speeds and lower latency, which means fewer interruptions during important tasks like video calls, file transfers, or cloud application use. Wireless connections provide flexibility and mobility but can be less reliable and more vulnerable to interference or cyber risks if not properly managed.
For Australian small and mid-sized businesses (SMBs), downtime caused by poor network performance can lead to lost sales, frustrated staff, and damaged customer trust. Additionally, wireless networks without strong security controls may expose sensitive business data to hackers, increasing compliance risks, especially if you handle customer information or financial data.
A practical example
Consider a 50-person accounting firm in Melbourne. Their staff need to access large financial files and cloud-based accounting software throughout the day. Initially, the firm used Wi-Fi for all PCs to allow easy desk moves. However, they experienced frequent slowdowns and occasional disconnections during peak hours, delaying client work and causing frustration.
After consulting their managed IT provider, they switched most fixed desks to wired Ethernet connections, reserving Wi-Fi for mobile devices and meeting rooms. This change improved network stability and speed, reducing downtime and boosting staff productivity. The IT team also implemented strong Wi-Fi encryption and regular password updates to secure the wireless network.
Checklist: What to consider and ask your IT provider
- Network speed and reliability: Ask about the expected performance differences between wired and wireless for your office size and layout.
- Security measures: Check what encryption standards (e.g., WPA3) and access controls are in place for Wi-Fi.
- Device usage patterns: Identify which roles or departments need mobility and which benefit from stable wired connections.
- Infrastructure readiness: Confirm if your current cabling and switches support the desired wired speeds (e.g., Gigabit Ethernet).
- Support and monitoring: Ensure your IT provider offers ongoing network monitoring to quickly spot and fix connectivity issues.
- Backup connectivity plans: Discuss options for failover connections or guest Wi-Fi to maintain business continuity.
Next steps
Balancing wired and wireless connections in your office depends on your specific business needs, physical space, and security priorities. A trusted managed IT provider can assess your current setup, recommend the right mix, and help implement solutions that minimise downtime and protect your data. Consider scheduling a network review to ensure your office connectivity supports your business goals effectively.
