The TP-Link TL-SG108 is one of the most popular 8-port unmanaged gigabit switches on the market, and for good reason — it is a quiet, sturdy, plug-and-play box that simply extends a home or small office network with eight more wired ports. At around $25 it is genuinely affordable, and it has built a vast positive buyer-review base behind it. This TP-Link TL-SG108 review covers the specifications, real-world performance and value.

Throughput & Real-World Speed
The TL-SG108 is a true gigabit switch — every port runs at up to 1 Gbps full-duplex, so a wired client can theoretically push 125 megabytes per second of throughput, the practical ceiling of gigabit Ethernet. To actually hit that speed you need the rest of the chain to keep up: a CAT5e or CAT6 cable in good condition, a gigabit-capable NIC at both ends, and source storage fast enough to feed the link. With a 16 Gbps non-blocking switching fabric, the TL-SG108 can serve every port simultaneously at full gigabit without internal bottlenecks. For gaming, file transfers between PCs and a wired connection to a NAS, it is more than enough — modern online games use only a few megabits per second, so the value of a wired switch is not raw bandwidth but rather rock-solid latency and zero packet loss compared with WiFi. For the network basics, see our low-latency gaming network guide.
Managed vs Unmanaged Capabilities
The TL-SG108 is unmanaged — it has no web interface, no settings, no VLANs and no QoS. You plug it in and it works. That is the entire pitch: a $25 box that takes one upstream Ethernet cable and turns it into eight ports, with no configuration to learn or break. For most home users that is exactly the right answer. If you need VLANs to segment a guest network or IoT traffic, or QoS to prioritise gaming or streaming, you need a managed or Easy Smart switch — and TP-Link’s TL-SG105E and similar models step up to that role at a modest price increase. But for the very common task of simply adding wired ports behind a router, the unmanaged TL-SG108 is the simplest, cheapest and most reliable option.
PoE Power for IP Cameras / APs
The TL-SG108 does not include Power-over-Ethernet, so any device that needs PoE — most ceiling-mounted WiFi access points, many IP security cameras, some VoIP phones — will need a separate power source or a dedicated PoE injector. For a typical home setup of PCs, consoles, smart TVs and a NAS that is not a problem; none of those devices use PoE. If you intend to mount one or two cameras or APs you can add an inline PoE injector for each, but if you have several PoE devices it is cheaper and tidier to choose a PoE-capable switch outright. Buyers building a small camera system should consider this carefully before purchase.
Build Quality, Heat & Noise
TP-Link houses the TL-SG108 in a sturdy steel case rather than the plastic shell common at this price, which is a genuine plus — the metal shell helps with heat dissipation, gives the unit some weight so it stays put, and feels durable. The switch is completely fanless, so it is silent and well suited to a living room or bedroom desk. In normal use it runs only mildly warm; even saturating multiple ports at gigabit it does not heat up enough to be concerning. The chassis includes mounting holes for wall installation, which is helpful for tidy installations in cupboards or behind desks.

Best For – Gaming Home / SMB / Pro
The TL-SG108 is squarely a home and small-office switch. For the gamer it is ideal: take one Ethernet cable from the router and turn it into eight reliable wired ports for a gaming PC, console, smart TV, NAS, streaming box, smart hub and so on, eliminating WiFi variability from the most latency-sensitive devices. For a small office it is fine for connecting a handful of desks where no advanced features are needed. It is not the right tool for a professional environment that needs VLAN segmentation, monitoring or PoE, but it was never built for that role — at $25 the TL-SG108 is built to be the simplest, most cost-effective answer to ‘I need more wired ports’. For the wider network, see our best gaming routers guide.
Verdict
At around $25 the TP-Link TL-SG108 is one of the easiest network purchases to recommend. It is a sturdy, silent, fully gigabit, plug-and-play 8-port switch with a vast positive buyer-review base, from a brand that is the default choice in this category. Its limitations — no PoE, no management, no SFP — are honest and well understood, and at this price they are the right trade-offs for a home or small-office switch. For most readers looking to add wired ports to their network, it is the default choice. Buyers who need fewer ports can step down to the TL-SG105; buyers who want PoE or VLANs should look at TP-Link’s Easy Smart or PoE models instead.

Frequently Asked Questions
Is the TP-Link TL-SG108 a managed switch?
No. It is a fully unmanaged plug-and-play switch with no web interface or settings — you plug it in and it works. If you need VLANs or QoS, choose an Easy Smart or managed model instead.
Does the TL-SG108 support PoE?
No. The TL-SG108 does not provide Power-over-Ethernet. To power an IP camera or access point you will need a separate PoE injector or a PoE-capable switch.
Is the TL-SG108 good for gaming?
Yes. As a true gigabit switch with very low internal latency, it is ideal for wiring a gaming PC, console or streaming device for the most stable, low-latency connection.
Does the TP-Link TL-SG108 have a fan?
No. The TL-SG108 is completely fanless, which makes it silent — a useful trait for a living room or bedroom installation.
