Expand Your Router With an Ethernet Switch That Works

Why an Ethernet Switch Beats Your Router’s Limited Ports

An Ethernet switch expansion is a small network device that connects to one port on your router and breaks it out into several additional Ethernet ports so you can hardwire more devices and improve wired network performance without replacing your router or mesh system entirely.

For most people, the Netgear 5‑Port Gigabit Network Switch (GS305) is the right answer because it is a reliable, plug‑and‑play way to turn one router port into five Gigabit ports in a compact, fanless metal case. Modern routers and mesh kits perform well but often ship with only a few Ethernet jacks, so you quickly hit router port limits when you plug in a TV, console, smart hub, and maybe a NAS. A switch fixes that in one move and lets you keep your core devices wired for maximum speed, efficiency, and security. If your Wi‑Fi drops even briefly, you feel it as buffering or lag, whereas Ethernet gives a stable link that is far less prone to interruptions.

When to Add a Switch: TVs, Consoles, and Busy Homes

You should add an Ethernet switch as soon as you have more wired‑worthy devices than your router can handle. Smart TVs, gaming consoles, desktop PCs, work laptops, and NAS drives all benefit from hardwiring. Ethernet cuts Wi‑Fi interference, which means more stable, low‑latency performance for streaming and gaming, and far fewer drops or slowdowns when your network gets busy.

Hardwiring a TV is a clear win: Ethernet gives it a more stable connection that is less prone to drops, so movie nights avoid random pauses and buffering. At the same time, plugging in the TV removes it from the Wi‑Fi pool, freeing bandwidth for phones, tablets, and laptops so the wireless side feels less congested. The same logic applies to consoles and PCs that stay in one place—if it does not move, it deserves a cable. Use the switch at your router or at an entertainment centre to fan out short patch leads to everything there.

Managed vs Unmanaged: Why Simpler Wins at Home

The key choice is managed vs unmanaged switches. Managed models expose advanced controls such as VLANs to segment networks and QoS (Quality of Service) rules to prioritise certain traffic—handy for complex home labs or pro‑style setups. Unmanaged switches are the opposite: plug‑and‑play devices that work out of the box without any configuration and at a lower cost. For typical home Ethernet switch expansion, unmanaged is the better choice because it keeps your setup simple while still lifting wired network performance.

The Netgear GS305 is an affordable unmanaged switch that “is nice and straightforward” if you only need a few extra ports. It offers five Gigabit ports in a compact metal shell, runs silently thanks to its fanless design, and only needs power and a single uplink cable to your router to start working. According to the reviewer who has used several switches from this brand, they have proved reliable and well made over time. That combination of reliability, silence, and zero setup is exactly what most households need.

Our Top Pick: Netgear GS305 Specs, Strengths, and Drawbacks

If you want one switch recommendation that fits almost every home, pick the Netgear 5‑Port Gigabit Network Switch (GS305). It gives you enough headroom for a TV, console, streaming box, and a work PC, with one port left for expansion. The metal housing feels solid, it stays quiet thanks to fanless cooling, and the LEDs show at a glance which ports are active and linked at Gigabit speeds. You can wall‑mount it or hide it in a cable box near your gear.

The main downside is capacity: power users or large homes might eventually want more than five ports, and unmanaged design means no VLANs or advanced QoS. It also lacks PoE, so you cannot power cameras or access points over the same cable. Still, if you are focused on stabilising a few key devices and beating router port limits, this one box solves the problem with minimal fuss.

Practical Placement and When a Switch Is Not Worth It

Placement matters more than most people think. Position switches near clusters of devices—under the TV, in a home office, by your NAS rack—so you run a single longer cable back to the router and then short patch cables to each device. This keeps cable runs tidy while preserving throughput across the wired network. For high‑end setups, pairing Gigabit switches with multi‑gigabit backbone gear (2.5GbE, 5GbE, or 10GbE models) gives you room to grow as internet speeds and local file transfers climb.

There are times an Ethernet switch is not the answer. If your TV or console is far from the router, dragging a long cable across your home can be a hassle or a tripping risk. Some TVs also fail to take full advantage of higher Ethernet speeds due to their own hardware limits, meaning Wi‑Fi can be similar or even faster unless you adjust the setup. In those cases, you might keep Wi‑Fi for that device and reserve the switch for gear that is closer or more latency‑sensitive, like gaming rigs and NAS drives.

Buy if / Skip if

• Buy the Netgear GS305 if you have run out of router ports and want a simple way to add five reliable Gigabit connections without configuration.
• Skip the Netgear GS305 if you know you need VLANs, detailed QoS controls, or other managed‑switch features for an advanced home network.
• Buy the Netgear GS305 if you want to hardwire a TV, console, and work PC to reduce drops, buffering, and latency compared to Wi‑Fi.
• Skip the Netgear GS305 if your main streaming devices sit far from the router and you are unwilling to run any Ethernet cabling.
• Buy the Netgear GS305 if you prefer fanless, silent hardware that can hide in a cable box or mount discreetly on a wall.
• Skip the Netgear GS305 if you require Power over Ethernet to run cameras or access points from the same switch, as this model does not provide PoE support.
