As home networks become more complicated -- and more wireless -- it can seem like wired networking is old hat. Who needs a hard-wired connection from one of the best network switches when you can get Gigabit speeds or better from a shiny new Wi-Fi 6E router? Then again, a wireless connection can introduce many variables. Protocol compatibility, wireless interference, signal-obliterating wall materials, or just poorly-designed radios/antennas can all slow a speedy gigabit connection to a comparative crawl.

Conversely, a good, solid wired connection can cut out these and other shortcomings of an over-the-air signal, while providing higher speeds and a reliable, stable connection. With typical routers only offering no more than 4 Ethernet ports -- or sometimes fewer -- the best network switches step in to fill the gap, giving you more ports to plug your wired devices into. Not only that, but they can also spread out some of the load on your network, freeing your router up to carry out its primary mission of getting internet service to all the wireless devices on your network that need it.

Like the Ethernet hubs that came before them, one of the best network switches can add ports to your network, allowing you to hardwire more devices to your router than would otherwise be possible. What’s more, they can filter your LAN traffic, moving prioritized packets to the front of the line to keep things running smoothly. And most normal networks don’t require more than the simple solution of an unmanaged switch.

We did some hands-on testing with several different (mostly unmanaged) network switches to see which ones are the best for most people. This is by no means an exhaustive list, but we believe these network switches are solid options for each given use case. 

Shopping Tips for Best Network Switches 

When looking for the best network switches, consider:

Number of Ports: You can get anywhere from four all the way up to 48 or more Ethernet ports. Some also have USB ports.

Managed or Unmanaged: If you just need to get wired internet access to a few devices, then you’ll want an unmanaged network switch, which we recommend for most users. This doesn’t mean the switch has no features -- unmanaged switches can often do plenty of fancy things, from traffic prioritizing QoS to loop detection. 

Managed network switches are more secure and can monitor traffic for troubleshooting purposes or separate chunks of your network into their own virtual local area networks, or VLAN. If going this route, you’ll also want to make sure your router is compatible with VLANs -- a non-bridged setup using Amazon’s eero mesh routers, for instance, makes VLANs unusable.

Power Needs: Most won't need it, but certain devices can get power over Ethernet if your switch supports it. 

Network Speed: Gigabit Ethernet is the minimum speed, but you should consider going with 2.5 GbE or higher, even if you don't need it right now, because future devices may benefit.

TP-Link TL-SG108, Best All-Around Budget Network Switch  (Image credit: Tom's Hardware)

Best All-Around Budget Network Switch

Ports: 8 | Dimensions: 158×101×25 mm | Status Lights: 2 per port (Speed/Link/Activity) | Power Supply: External | Cooling: Fanless | Warranty: Limited Lifetime

Nice build quality
Dim LEDs
Lifetime Warranty
No Loop Detection

When it comes to 8-port network switches for the home or small office network, it’s hard to beat the TP-Link TL-SG108. It’s compact, has a fanless metal enclosure, plus dimmer-and-less-distracting LEDs than some of its competitors (Don’t worry; there are still two per port, each informative based on color and/or blinking pattern). The TL-SG108 also features traffic-prioritizing QoS, full duplex flow control, auto-negotiating ports for choosing transfer speed up to a gigabit, and simple, plug-and-play setup. This best network switch performed at rough parity with other 8-port switches we tested and ran cool.

The one notable omission from this network switch is loop detection, which prevents your network being slowed to a crawl or disabled entirely by looped network traffic. This can be a very important troubleshooting tool in a complicated network, with visual indicators on a switch that tell you which Ethernet ports to investigate for issues. 

If loop detection is a requirement, we recommend either the ProSAFE Netgear GS108 or the Cisco CBS110-8T-D. However, each of those switches, at $40 and $68 respectively, is also significantly more expensive than the less-than-$20 TP-Link. And we do not feel that, for most people, loop detection justifies the extra cost. 

Lastly, the TP-Link features a nice limited lifetime warranty, providing a nice peace-of-mind that you wouldn’t get from, say, the similarly-inexpensive Netgear GS308, which only has a 2-year warranty. On the whole, even if you only need 5 extra ports, we recommend this switch for its price, feature set, and build quality to expand the wired capability of your network now and in the future.

QNAP QSW 1105-5T, Best 5-Port Network Switch  (Image credit: Tom's Hardware)

2. QNAP QSW 1105-5T

Best 5-Port Network Switch

Ports: 5 | Dimensions: 180×145×35 mm | Status Lights: Ports: Speed/Link/Activity Loop LED: Loop Per System: Power/Status | Power Supply: External | Cooling: Fanless | Warranty: 2 years

All 5 Ports are 2.5 GbE
Inexpensive relative to other 2.5 Gb switches
Nice feature set
Very large for a 5-port switch
No status LEDs opposite the ports side
No QoS

This network switch from QNAP seems pricey at first blush, but its 5 ports each offer 2.5 Gbps throughput over Cat 5e or better cabling -- something you would expect to pay significantly more for than the QSW 1105-5T’s $109 MSRP (D-Link’s DMS-106XT for example, due later this year, will cost 3 times that for the same port count). And opting for 2.5 GbE now will give you a fair amount of future proofing, as motherboards, laptops, and other devices move to supporting faster throughput. 

Other than that, the QNAP QSW 1105-5T delivers everything else you should expect in one of the best unmanaged network switches: plug-and-play setup, solid metal housing and fast, silent operation thanks to its fanless design. This network switch is fairly large compared to other 5-port switches, making even many 8-port models seem small by comparison. So you’ll want to take a look at the dimensions before buying one. 

The QNAP QSW 1105-5T also expectedly draws more power than your average 5-port switch: We recorded 6.8 watts with minimal traffic and 8.1W when all the ports were in use, which is in line with QNAP’s stated max of 12W. Speaking of power, its external power supply plugs into the front, which can be nice if, say, this switch will be on your desktop and you’d rather all the cables face toward the back. However, there are no status LEDs on the other side if you situate it this way.

Beyond being fast, the QSW 1105-5T features loop detection and full-duplex flow control -- meaning it can slow traffic going to a device if that device seems to be having a hard time keeping up, preventing things like packet loss. There is no apparent QoS feature, though with 25 Gbps maximum switching capacity, you may never miss it. In testing with a 2.5 GbE Thunderbolt 3 Ethernet adapter, we got a little above 2,000 Mbps transfer speeds using Cat 6 cable. For reference, that’s a transfer of a 4.5 GB file in about 17 seconds.

This switch is often questionably posited as good for gamers. But while it will mean faster game downloads if you have a fast ISP, there is no reason to believe it will help with latency. (Imagine bandwidth being the width of a highway, and latency the speed limit). 2.5 GbE’s more apparent benefits come for those who transfer large amounts of data locally, say to a NAS. Additionally, since improvements brought by the 802.3bz protocol make 2.5 Gbps data transfers possible with Cat 5e cables, there is no need to upgrade an already gigabit-equipped network when adding this switch to it. All told, for just a touch over $100, the QNAP QSW 1105-5T switch really is a boon for anyone who wants to boost the hardwired speed of their local network. 

Best Small Power Over Ethernet (PoE) Network Switch

Ubiquiti Unifi USW-Flex, Best Small Power Over Ethernet (PoE) Network Switch  (Image credit: Tom's Hardware)

3. Ubiquiti Unifi USW-Flex

Best Small Power Over Ethernet (PoE) Network Switch

Ports: 5 | Dimensions: 122.5×107.1×28 mm | Status Lights: 2 per Port: PoE, Link/Speed/Activity System: Status | Power Supply: PoE | Cooling: Fanless | Warranty: 2 years (if purchased from Ubiquiti), 1 year from authorized reseller

802.3af PoE power
Small Size
Weather Resistant
Gigabit Speeds
Can run hot
No real SSH capability
Some features are too obscure
USW-Flex Settings are somewhat obscured in the UniFi Controller software

This is a complicated recommendation. Recent news concerning a privacy breach at Ubiquiti notwithstanding, we believe the Unifi USW-Flex to be the best network switch for anyone looking to bring PoE to the edge of their network. This affordable, 5-port wonder can supply up to 15.4 watts of power to each of its four output ports. Note the use of “up to” here; once you’ve got all ports occupied, the 46-watt power budget will prevent 15.4 watts going to all four ports at once. So if you are using up all of that power at every port, the fourth port gets reduced priority and lower wattage. The PeE features also only apply provided the Unifi USW-Flex is powered itself by a proper PoE injector. If you’re uncertain which injector to buy, Ubiquiti sells a fairly inexpensive one

Although it’s a managed switch, the Unifi USW-Flex lacks certain key features like Spanning Tree Protocol, which helps prevent switch loops, or the ability to use SSH for extensive command-line-management (although you can SSH in for some basic functionality like firmware updates), it works well as an edge-of-network device to power things like IP cameras or sensors that you may want to have minimal wiring going to.

Additionally, the USW-Flex is built for outdoor use and comes with multiple mounting options - either magnetic or pole/wall mounts - as well as a hood that can be affixed over the Ethernet ports to help prevent moisture ingress when it rains. As a quick aside, part of this switch’s outdoor-friendly design is its recessed ports, which can be hard to remove an RJ45 connector from, as there isn’t much room for your fingers to squeeze the connector’s release clip.

In testing, we found that, when using the Flex without configuration, it worked about as well as any other in this list: Transfer speeds were solid, and faster than other gigabit switches tested under load. It’s worth noting here, however, that the Ubiquiti does get quite hot, sitting easily over 100 degrees Fahrenheit at idle and getting as warm as 118.7 degrees F with every port in use --  and that’s in a cool room, with plenty of air movement. It’s rated to operate in temperatures up to 149 degrees F (at 25W output - 131F at 46W), but it would still be a good idea to keep it in a shaded area if using outside, as direct summer sun could shorten its lifespan or impact performance. 

The USW-Flex comes with other caveats, too. The switch is managed via a browser-based GUI (the same general-purpose interface that is used for all other UniFi gear, which is nice if you have an all-UniFi network, but irritating and confusing if you only have this switch. And though it can function without ever touching its settings, there are some you’ll have to change to access promised capability. For instance, the switch does not default to the 802.3bt protocol that provides for the full 46-watt power budget, so you must change the power source under settings to PoE Injector. 

You’ll want to be certain that the device powering it is outputting with the 802.3bt protocol, or you will not be able to get all 46 watts. The final note is applicable to managed switches in general: If setting up and using a virtual LAN, you would do well to first ensure that your router supports VLANs -- Amazon’s eero, for instance, currently does not. In spite of all of this, the convenience of bringing both Gigabit Ethernet and 802.3af PoE power from four ports to anywhere in-or-out of your home for a hundred bucks is quite a weighty item in the “pro” column in our opinion.

Zyxel XGS1010-12, Best Versatile Network Switch  (Image credit: Tom's Hardware)

4. Zyxel XGS1010-12 (Unmanaged)

Best Versatile Network Switch

Ports: 10 (8 Gigabit, 2 2.5 Gb), 2 SFP+ | Dimensions: 250×104×27 mm | Status Lights: Gigabit Ports: Link/Activity (Green Gb, Amber Fast ethernet) 2.5 Gb Ports: Sky Blue: 2.5 Gbps 10 Gb SFP+: Blue: 10 Gbps | Power Supply: External | Cooling: Fanless | Warranty: 5 years

Options for both 2.5 Gb and 10 Gb connections
Great all-around performance
Warranty is decent, but not great
Can run a little hot

In between 8-and-16-port switches, you have some funky units like this ZyXel XGS1010-12. It’s billed on the box as a desktop switch with 8 gigabit ports and four bonus ports in the form of two 2.5 GbE and two 10 GbE SFT+ uplink ports. The latter fiber Internet customers would recognize as the data port on a fiber ONT (Optical Network Terminator -- think of it like a Fiber modem for customers without last-mile copper). 

Physically, the XGS1010-12 has a solid metal enclosure, a fanless design, an external power supply, with all the ports on one edge while the power supply connects in the back. Each port has two LEDs for power and status, with colors to indicate the speed of connection being provided. It boasts QoS, Auto MDI/MDIX in all ports, and flow control.

The switch did well in testing, putting up numbers slightly better than the QNAP on its 2.5 Gb ports, while its gigabit ports performed very well. Under heavy traffic, we saw no performance loss, which is to be expected given its total bandwidth of 66 Gbps. The ZyXel was the second-hottest of the switches tested, peaking at 100 degrees Fahrenheit under load - which is definitely going to be warm to the touch, but not concerningly so. Just make sure the box has a bit of ventilation. 

Though the ZyXel XGS1010-12 will run you $150 when bought at its MSRP, the addition of two 2.5 GbE ports and two 10 GbE SFP+ uplink ports makes this a very good deal relative to similar switches, which typically go for hundreds of dollars and lack this much versatility. If you have a high-speed NAS or need a super-fast connection between a couple of your computers, this switch lets you do that on the cheap, while still serving as a great hub for your other devices. 

Lastly, it is somewhat unclear what the warranty terms are for this switch (the included documentation only refers the buyer to the website, where it’s not explicit under which warranty it falls, Standard or Limited Lifetime). But we contacted Zyxel and were able to confirm that while XGS1010-12 falls under the 2-year Standard Warranty, this particular switch is among those that have had their term extended to 5 years. That still isn’t amazing, but it’s better than what you’ll get from many cheap switches.

TP-Link TL-SG116, Best Budget 16-Port Network Switch  (Image credit: Tom's Hardware)

Best Budget 16-Port Network Switch

Ports: 16 | Dimensions: 286×111.7×25.4 mm | Status Lights: Ports: link/act Unit: Power | Power Supply: External | Cooling: Fanless | Warranty: Limited Lifetime

Great warranty
No Loop Detection
Not quite as good a deal as the TL-SG108

TP-Link is once again a best network switch choice here because of its affordability. At $50 it’s not quite as much a deal as the TL-SG108, but finding a lower-cost 16-port unmanaged switch with the kind of reliability, warranty, and proven performance offered by TP-Link would be challenging and perhaps involve some good fortune. 

With the TL-SG116, you’ll get the same benefits as the 8-port version: IGMP snooping, flow control, QoS, etc. It also has the same unobtrusive LEDs, metal housing, and fanless construction and limited lifetime warranty. Like its 8-port sibling, however, it lacks loop detection, which may be a bigger issue when you’re the type of user looking for a 16-port switch.

The TL-SG116 performed as well as can be expected in testing, with a small drag in transfer speed under load, but otherwise maintaining at least near-gigabit speeds while testing with iperf and normal file transfers, streaming, and gaming. If you have more complicated network needs, we recommend the D-Link DGS-1100-16V2 Easy Smart Managed Gigabit desktop switch, which features an approachable GUI management interface and a well-rounded feature set for $109.99.
