The MS105GS is a sturdy, unmanaged gigabit switch designed to upgrade wired networks in homes, small offices, dorms, or entertainment setups. With five 10/100/1000 Mbps RJ‑45 ports featuring auto‑negotiation and Auto‑MDI/MDIX, it delivers a total switching capacity of 10 Gbps—enough to support simultaneous high-bandwidth activities like 4K streaming, gaming, and backups
Design & Build
- Steel housing: Provides durable, EMI-resistant, fanless operation, and supports both desktop and wall‑mounted installation
- LED indicators: Show power/status and link activity, using green (Gigabit) and amber (Fast Ethernet) flashes for quick diagnostics
Key Features
- Plug‑and‑Play simplicity: No setup required—just connect power and Ethernet cables
- Energy efficiency: “Green Ethernet” technology reduces power usage by adjusting based on cable length and connection status (up to 82% power savings claimed)
- Reliable switching: Store-and-forward architecture, IEEE 802.3x flow control, and a MAC address table with 2K entries ensure stable data transfers, even with jumbo frames up to 9 KB

Benefits
- Great value: Often available for under $25–30, delivering full Gigabit performance on a budget
- Green and efficient: Lower power consumption compared to older models.
- Quiet and compact: Fanless design ensures silent operation; the metal enclosure is both sturdy and thermally efficient.
- Versatile use cases: Perfect for expanding wired connections to PCs, consoles, IP cameras, smart TVs, printers, NAS, and more
Considerations
- It’s unmanaged, meaning no VLANs, QoS, link aggregation, or management interface—pure plug-and-play.
- No PoE support; powered devices need separate adapters.
- Some users report occasional long-term reliability issues: one Amazon review noted that ports started degrading months after the warranty ended . While not universal, it’s something to be aware of.
Final Verdict
The MERCUSYS MS105GS is a compact, reliable, and energy-conscious switch ideal for anyone needing to expand gigabit wired networking without complexity. It’s a strong pick for gaming setups, home offices, or media rooms, offering silent operation and rock-solid performance at a low price. If you require advanced management features, PoE, or worry about durability over time, you might consider investing in a managed or more premium model—but for simple, everyday networking, this one punches well above its weight.
