What Is a Network Switch? Expand Your Wired Network with a USB-Powered 5-Port Gigabit Switch

One Ethernet wall outlet can feel limiting when a desk needs connections for a computer, printer, gaming console, and other equipment. A network switch provides a straightforward way to add wired connections without running a separate cable from every device back to the router.

The GenixLinks 5-Port Gigabit Ethernet Switch with USB-C Power expands one existing router or local network connection to as many as four additional wired devices. Its unmanaged design requires no drivers or software configuration, while USB power makes it convenient for desks, meeting areas, kiosks, and temporary workspaces.

What Does a Network Switch Do?

A network switch connects multiple Ethernet devices within a local network. It learns which devices are reachable through its ports and forwards ordinary unicast traffic toward the appropriate destination. This lets computers, printers, network storage, and other devices communicate through a shared network infrastructure.

For internet access, connect the switch to a LAN port on an existing router. The router continues to provide services such as routing, address assignment, and internet access; the switch adds more physical Ethernet connections. A switch does not create an internet connection by itself or replace the router functions required by a typical home or office.

Ethernet Switch vs. Ethernet Splitter

People often search for an “Ethernet splitter” when they need to connect several devices to one cable. The important distinction is whether the product is an active network switch or a passive cable accessory.

An active Ethernet switch allows connected devices to use the network simultaneously. Passive splitters do not provide the same switching function and may require paired accessories or impose specific wiring and speed limitations. For expanding a router port into several usable network connections, an unmanaged switch is the practical choice.

The GenixLinks product is an active, powered Ethernet switch even though its product name includes “splitter.” It manages network traffic among its ports so several devices can remain connected at the same time.

Five Gigabit Ports: How Many Devices Can You Connect?

The GenixLinks switch has five RJ45 Ethernet ports, each supporting a link rate of up to 1Gbps with compatible devices and cabling. In a typical installation, one port connects to the router or an existing network outlet, leaving four ports for local devices.

For example, a home-office installation might connect the switch to a router through a wall outlet, then connect a desktop computer, a printer, a NAS, and a gaming console. All four devices can access the network simultaneously.

The 1Gbps figure describes the maximum link rate of each compatible connection. Devices communicating through the same router uplink share that uplink’s available bandwidth. Multiple downloads do not each receive an independent 1Gbps internet connection, and actual transfer speeds depend on protocol overhead, storage performance, network traffic, and the rest of the equipment.

USB-C Power for Flexible Placement

A distinctive feature of the GenixLinks 5-port Gigabit Ethernet switch is its USB-C power input. It requires a compatible USB power source supplying 5V/0.5A. Suitable sources can include a powered USB port on a laptop, monitor, or docking station, a USB power adapter, or a compatible power bank.

The included six-foot USB-A to USB-C cord provides flexibility when placing the switch on a desk or near network equipment. A USB power adapter is not included, so select a suitable power source before installation.

The USB connection supplies power to the switch. Network traffic travels through the RJ45 Ethernet ports. Connecting the power cable to a laptop does not turn the switch into a USB Ethernet adapter; the laptop still needs an Ethernet connection to participate in the wired network.

When using a computer, monitor, or dock for power, check whether its USB port remains powered during sleep or shutdown. If that port turns off, the switch and the devices relying on it lose their network connection. Use a suitable always-on USB power source when uninterrupted access is needed.

Unmanaged Design: Connect and Start Using It

An unmanaged switch handles basic network expansion without a management interface. The GenixLinks model needs no driver installation or software configuration. Connect power, attach the existing network connection, and connect the wired devices.

This makes it suitable for straightforward installations involving Windows, macOS, ChromeOS, and Linux computers as well as Ethernet-equipped consoles, smart TVs, printers, and network storage. Each device still needs its own working Ethernet interface and any configuration required by the surrounding network.

For requirements such as administrator-configured VLANs, detailed traffic monitoring, or other managed-switch functions, choose equipment explicitly designed for those capabilities.

Where a Compact Ethernet Switch Helps

Home offices and shared desks

Expand a single wall outlet to connect computers, printers, and storage. Wired connections can provide consistent performance where wireless signals are weak or the Wi-Fi network is busy.

Gaming and entertainment areas

Connect a console, smart TV, streaming device, and other Ethernet equipment through one existing network cable. Ethernet can reduce exposure to wireless interference, although internet latency still depends on the router, service provider, remote server, and network load.

Kiosks, trade shows, and temporary workspaces

USB power can simplify deployment where a suitable USB power source is already available. A switch can distribute an approved wired connection to several devices without moving cables repeatedly.

Hotel workspaces

A switch may help share a wired connection among permitted devices, but hotel and other managed networks can restrict the number of connected devices or require individual authentication. Confirm the network’s access policy first.

Desktop or Wall-Mount Installation

The switch can sit on a desktop or be secured using the included mounting screws or adhesive hook-and-loop strips. Mounting can keep cables organized in a kiosk, behind a desk, or near a wall outlet.

Choose a position within reach of the USB power source and Ethernet cables. Leave space for connectors and avoid placing tension on the ports. When using adhesive mounting, check that the surface is suitable and that the attachment can support the switch and connected cables.

How to Set Up the GenixLinks 5-Port Gigabit Switch

1. Choose the power source. Use a compatible USB source supplying 5V/0.5A. If continuous connectivity is required, confirm that it stays on.
2. Connect USB power. Attach the included USB-A to USB-C cable between the power source and the switch’s USB-C power input.
3. Connect the existing network. Run an Ethernet cable from a router LAN port or a working network wall outlet to one RJ45 port on the switch.
4. Connect up to four devices. Use the remaining Ethernet ports for computers, printers, consoles, smart TVs, or other network equipment.
5. Check connectivity. Confirm that each device receives the appropriate network settings and can reach the required local resources or internet services.
6. Secure the installation. Place the switch on a desk or use the included mounting accessories, keeping cables supported and accessible.

Use a single uplink to the existing network for a straightforward installation. Connecting multiple cables between the switch and the same network can create a switching loop unless the equipment and configuration explicitly support that arrangement.

Understanding Gigabit Ethernet Performance

Gigabit Ethernet offers a link rate of up to 1000 megabits per second. Megabits and megabytes are different units: 1Gbps corresponds to 125 megabytes per second before network overhead. Application transfer speeds are lower and depend on the devices and software involved.

For a Gigabit link, use suitable Ethernet cabling, such as properly installed Cat5e or better, and confirm that both endpoints support 1Gbps. A slower router port, older device, damaged cable, or poor termination can reduce the negotiated rate.

A Gigabit switch also does not increase the speed of an internet subscription. A 300Mbps service remains limited by that service even when the local Ethernet connection runs at 1Gbps. For local transfers, the source and destination storage systems can become the limiting factor.

USB Power and PoE Are Different

This product is specified to receive power through USB-C. That does not establish Power over Ethernet support. Do not assume that it can power a PoE camera or access point through an RJ45 port, or that it can receive its own operating power from an Ethernet cable.

If the installation requires PoE, choose a switch or injector explicitly rated for the connected device’s PoE standard and power requirement. For this GenixLinks model, plan on the specified USB power connection.

Troubleshooting a Wired Connection

• All devices disconnect: Check the USB power source and the Ethernet uplink. Confirm that the power source did not turn off during sleep.
• One device cannot connect: Test another Ethernet cable and another switch port, then check that device’s network settings.
• The link runs below Gigabit speed: Confirm that both endpoints support 1Gbps and test with a known-good Cat5e or better cable.
• Local access works but internet access fails: Check the router, modem or gateway, and internet service. The switch relies on the existing network for internet access.
• Performance drops during simultaneous transfers: Check whether multiple devices are sharing the same uplink or internet connection.
• A managed network rejects additional devices: Contact the network administrator or venue operator about access limits and authentication.

A Simple Way to Add More Wired Connections

A 5-port Gigabit Ethernet switch is a practical addition when one router port or wall outlet needs to serve several devices. The GenixLinks USB-C-powered Ethernet switch combines five Gigabit RJ45 ports, straightforward unmanaged operation, flexible USB power, and desktop or wall mounting.

Connect one port to the existing network, use the remaining four for wired devices, and provide a compatible 5V/0.5A USB power source. With suitable cabling and network equipment, it offers a convenient way to expand connectivity for home offices, entertainment areas, kiosks, and temporary workspaces.
