Most UK ISP routers (like those from BT, Sky, or Virgin Media) only feature four ethernet ports on the back. As you connect smart TVs, game consoles, security systems, and mesh nodes, you quickly run out of physical ports.
⚙️ Technical Standards & Reference Guide
What is a Network Switch & Why Do You Need One?
A network switch acts like an electrical extension lead for your network. You connect one port on the switch to your router, and the other ports on the switch become available to expand your wired network. A switch directs data traffic specifically between devices, maintaining high speeds.
Managed vs Unmanaged Switches: Simple Comparisons
Unmanaged Switches: These are completely plug-and-play. They have no software interface, require no setup, and automatically negotiate connection speeds. They are cheap, reliable, and ideal for standard home entertainment systems.
Managed Switches: These offer advanced control over your network traffic. They allow you to configure VLANs (Virtual Local Area Networks) to isolate smart home devices or IP cameras from your main computers, improving security. They also support QoS (Quality of Service) to prioritise gaming or video call traffic.
PoE Switches: Calculating Your Power Budget
A PoE (Power over Ethernet) switch sends power down the network cable to devices like security cameras, wireless access points, and VoIP phones. When buying a PoE switch, check its 'PoE Power Budget'.
If a switch has 8 ports but a total power budget of only 60 watts, you cannot connect 8 cameras that consume 10 watts each. Exceeding the power budget will cause the switch to shut down ports, taking your devices offline.
Switch Speeds: Gigabit, 2.5Gbps, and Future-Proofing
While Gigabit (1000Mbps) switches are the standard in 2026, 2.5Gbps and 10Gbps switches are becoming popular as UK broadband speeds exceed 1Gbps. If you have a fast fibre connection, using a 2.5Gbps switch for your main PC and network storage (NAS) ensures you don't bottleneck your local transfer speeds.
Always choose switches with metal casings. Metal casings dissipate heat much better than plastic, extending the lifespan of the internal capacitors and preventing lockups under heavy network loads.
