Zyxel 12-Port Multi-Gigabit Switch Review UK 2026

You’re about to spend a decent chunk of money on networking kit that’ll sit quietly in the background for years. I’ve spent the last two weeks hammering this Zyxel switch with everything from 4K video transfers to multi-device workloads, and I’m going to tell you exactly whether it’s worth your cash or if you should look elsewhere.

The port configuration is smart. Eight ports run at 2.5GbE (perfect for most modern devices), whilst four ports handle up to 10GbE for your heavy hitters like a NAS or a workstation with a 10GbE card. It’s unmanaged, which means you plug it in and it works. No configuration, no web interface, no messing about.

Jumbo frames are enabled by default (though there’s no way to configure this since it’s unmanaged). If your devices support it, you’ll see slightly better performance on large transfers. If they don’t, it doesn’t matter – the switch handles standard frames just fine.

What you don’t get is any management capability. No VLANs, no port mirroring, no QoS controls. For a home office or small business, that’s probably fine. But if you need to segment your network or prioritise traffic, you’ll want a managed switch instead.

Look, the performance is exactly what you’d expect from a decent unmanaged switch. The 10GbE ports hit 9.4Gbps in sustained transfers between my workstation and NAS, which is about as good as you’ll get in the real world once you account for TCP overhead.

The 2.5GbE ports are equally solid. I ran simultaneous transfers across multiple ports and saw consistent speeds without any drops. That’s the benefit of the 240Gbps switching fabric – there’s enough bandwidth that you’re not fighting for resources.

Latency is low (sub-millisecond for local traffic), and I didn’t see any packet loss during extended testing. For most home and small business use cases, that’s all you need to know.

After two weeks of constant use with all ports active, the chassis gets warm but not hot. I measured around 45°C on the top surface during heavy load, which is perfectly acceptable for fanless operation. The passive cooling works.

Port quality is good. The RJ45 sockets have decent retention (cables click in firmly), and I didn’t experience any loose connections during testing. The LED indicators are bright enough to see clearly but not obnoxiously bright if this is sitting near your desk.

One minor gripe: there’s no mounting hardware included. If you want to rack-mount this or stick it under a desk, you’ll need to sort out your own brackets or velcro. Not a deal-breaker, but it would’ve been nice to include some basic mounting options.

That simplicity is both a strength and a limitation. If you want plug-and-play networking, it’s perfect. If you need to configure VLANs or monitor traffic, you’re out of luck. Know what you’re buying here – this is an unmanaged switch, and that’s by design.

The LED indicators give you basic status info: link/activity lights for each port, and speed indicators showing whether you’re connected at 1G, 2.5G, or 10G. That’s enough for troubleshooting most issues (like spotting when a cable has negotiated down to gigabit when you expected multi-gig).

The TP-Link TL-SX1008 is cheaper and gives you eight 10GbE ports, but that’s overkill for most setups. Most devices don’t have 10GbE cards, so you’d be connecting them at 1GbE anyway (the TP-Link doesn’t support 2.5GbE). The Zyxel’s mixed port speeds make more sense for real-world deployments where you’ve got a few high-speed devices and several 2.5GbE ones.

For pure value, the Zyxel wins if you need that specific combination of 2.5GbE and 10GbE ports in an unmanaged package. The port count and fanless design justify the price point.

Value comes down to whether you actually need multi-gigabit speeds. If all your devices are standard gigabit, you’re wasting money – get a basic gigabit switch for under £50. But if you’ve got 2.5GbE or 10GbE devices, the Zyxel makes sense.

Breaking down the cost per port, you’re paying around £14 per multi-gig port. That’s competitive for unmanaged multi-gig switches, especially considering the fanless design and metal construction. Cheaper alternatives exist, but they usually compromise on build quality or port configuration.
