USB to 4-Port Gigabit Ethernet Switch - Compact Network Sharing

Our review of this USB to 4-Port Gigabit Ethernet Switch finds it best for users who need a compact, bus-powered way to share wired network access between multiple devices. The single biggest reason to buy is its combined design: it acts as a USB 3.1 Gigabit Ethernet adapter for a laptop or console and also functions as a 4-port Gigabit Ethernet switch, letting one wired uplink feed up to four devices without an external power brick. For anyone wanting reliable wired connections for a laptop, TV, or game console where no port exists, this unit solves that need cleanly.

Key Features

• Combined adapter and switch: Works as a Gigabit USB Ethernet adapter and a 4-port switch so a single dongle converts a host and shares a wired link with additional devices.
• Four gigabit ports: Provides three downstream ports plus one uplink port to connect to a wall jack, router, or wired network for shared access.
• Bus-powered operation: Draws power from the host USB connection or from a USB wall outlet when no host is present, eliminating the need for a bulky external power supply.
• Performance features: Supports Wake on LAN, full duplex, auto-sensing, jumbo frames, and IPv6 for better compatibility with modern networks.
• MAC pass-through support: Full support for MAC address pass-through with the included utility makes it practical for environments that require preserved device identities.
• Portable accessories: Includes a drawstring pouch and mounting strip to use the unit either as a mobile adapter or a semi-permanent mounted switch.

Who It's For

This device is aimed at laptop owners, streamers, and console players who need a reliable wired connection but lack a built-in Ethernet jack; it is also useful for small office or home setups that need a simple four-port switch without extra power. Reviewers found it especially handy for devices like the Nintendo Switch and small form-factor computers where adding a physical port is otherwise impossible.

Those who need managed switch features, PoE, or enterprise-class port configuration should look elsewhere; this is an unmanaged, bus-powered solution intended for convenience and compatibility rather than advanced network management or high-density deployments.

Pros & Cons

Pros

• Small, easy to tuck away or mount and simple to set up on Windows and Linux systems.
• Acts as both a Gigabit USB Ethernet adapter and a four-port switch, reducing the number of adapters needed.
• Powered from USB so no dedicated power brick is required for typical use.
• Includes practical accessories like a pouch and adhesive for flexible placement.

Cons

• Not a managed switch, so it lacks advanced features found in business-grade network switches.
• Relies on host USB power unless a USB wall outlet is used, which may limit scenarios with many high-power devices.
