The splitter is advertised for transfer rates of up to 1,000Mbps and works with Cat 5, 5e, 6, 7, and 8 Ethernet cables. It can sit between a router or switch and two wired devices, including computers, televisions, set-top boxes, and other RJ45-enabled equipment. The included USB power cable supplies the required 5V connection, while six LEDs help reveal which outputs are active.
The principal limitation is that this is not an unmanaged five-port switch, and its two outputs share the available network bandwidth. It also cannot operate without external power, which means finding a suitable USB power source is an important part of setup. The product information does not state that an Ethernet cable is included, so users may need to supply appropriate cabling.
This splitter makes sense for a home office, media area, or gaming arrangement where exactly two wired devices need access through one available port. It is less appropriate when a user expects each output to receive an independent full-speed line or needs more than two connections. For that limited use case, it offers a straightforward way to expand the network.
Quick Two-Device Network Expansion
The one-input, two-output layout provides a practical way to connect two devices when a router or wall outlet offers only one usable Ethernet port. It avoids the complexity of installing and configuring a conventional managed network switch.
Clear Activity and Connection Status
Six LED indicators make troubleshooting more convenient by showing which connected device is operating. The metal housing also gives the small adapter a more durable appearance than a basic plastic enclosure.

We may earn a commission when you buy through this link, at no additional cost to you.
Auto-negotiation and auto MDI/MDIX support simplify connection across different equipment. Port-based 802.1p/DSCP quality of service and IGMP snooping help prioritize suitable traffic, while IEEE 802.3X flow control supports more reliable data transfer. The fanless metal body remains quiet, and the shielded desktop or wall-mount design fits neatly into many environments.
Unlike a powered one-to-two inline splitter, the TL-SG105 requires an upstream Ethernet connection to a router, modem, or other switch. It also occupies more physical space, although its five-port capacity is substantially greater. This distinction is not a flaw for many buyers because a switch is often the more practical tool when several devices need independent ports.
The TL-SG105 is the strongest general recommendation for anyone who wants to expand a wired network without software setup or special configuration. It is particularly suitable for desktop computers, network storage, game consoles, smart televisions, and office equipment. Its five-port capacity, strong rating, and straightforward installation make it an excellent value-oriented centerpiece for a home network.
Five Ports for Flexible Networks
Five ports give users room to connect a router plus several wired endpoints. That makes the TL-SG105 more adaptable than the compact one-line-to-two-output splitters, particularly in an office or a home with multiple entertainment devices.
Traffic Features Without Configuration
Although it remains an unmanaged switch, the TL-SG105 includes useful traffic optimization features. Port-based QoS and IGMP snooping can improve the handling of latency-sensitive or multicast traffic without requiring software setup.

The splitter is stated to support Gigabit Ethernet transfer rates of up to 1,000Mbps and works with Cat5, 5e, 6, 7, and 8 cables. A Cat6 LAN cable and USB power cord are included. Setup consists of connecting the incoming Ethernet line, attaching the required power, and linking the desired devices, with no complicated configuration.
Four outputs still share the available upstream bandwidth, so heavy simultaneous downloads can reduce the speed observed by any one device. External power is also essential, and the device cannot be used as a standalone powered hub without an Ethernet source. The listing emphasizes portability, although the four-output arrangement is less discreet than a one-to-two adapter.
This LIEZHUA model is a good choice when two additional ports would not be enough and a compact inline format is preferred over a desktop switch. It can serve computers, televisions, cameras, and other Ethernet devices in a temporary or fixed installation. Buyers expecting four independent full-speed lines should instead choose a multiport managed or unmanaged switch.
Four Outputs in an Inline Format
The one-to-four arrangement expands a single wired line into four usable connections without requiring a full-size switch. This makes the adapter well suited to small workspaces where a few more ports are needed but a larger network enclosure would be inconvenient.
Useful Included Networking Cable
A Cat6 cable is included, allowing a basic connection without sourcing a compatible network lead separately. The USB power cord must still be connected to a suitable 5V source before the splitter will operate.

Buying Guide – How to Choose the Best Internet Splitter
A useful internet splitter should match the number of devices, existing wiring, power access, and traffic demands of your network. The most important distinctions are port count, whether the device is a true inline splitter or a conventional switch, and how its bandwidth is distributed.
Choose the Right Port Count
Begin by counting the wired endpoints that need a connection. A one-to-two splitter is sufficient for a computer and game console or a television and streaming box. A three-output model gives a little more flexibility for a desk, media area, or temporary office, while a four-output splitter can serve several devices without requiring a full-size switch. The TP-Link TL-SG105 is worth considering when five ports and a conventional switch architecture are preferable.
Understand Shared Bandwidth
An inline internet splitter divides the capacity of one upstream connection among its outputs. A device may achieve gigabit-class speeds under favorable conditions, but simultaneous activity can reduce the speed available to each endpoint. A conventional network switch offers more independent port-level behavior and is generally the better choice for a busy office. For light browsing, streaming, and gaming, a shared powered splitter remains an effective convenience.
Check Cable Standards
Most modern wired networks use Cat5e or Cat6 cables, but the products in this guide support combinations ranging from Cat5 through Cat8. Cat8 offers higher potential bandwidth over short runs, although the router, switch, endpoint, and installed wiring must also support the desired rate. Choosing broad compatibility makes an adapter easier to use in homes with mixed cable categories or older wiring that is still performing adequately.
Account for Power Requirements
Nearly all compact inline splitters require external USB power, and several listings explicitly warn that the device will not operate without it. A wall charger is often preferable to a computer USB port because it can provide a steadier source. The TP-Link TL-SG105 is a conventional self-powered switch, while the TP-Link one-to-two model includes a USB-C cable and a Cat5e network cable for a more complete setup.
Prefer a Conventional Switch for Busy Networks
A splitter is most useful when cabling is difficult or only one Ethernet port is available. A network switch is more appropriate when a router, modem, or wall jack already provides an upstream connection and several endpoints need dedicated ports. The TL-SG105 offers five Gigabit ports, fanless construction, traffic prioritization, and auto-negotiation, making it the more versatile choice for permanent multi-device networks.
Evaluate Port and Network Features
Compact models can include LEDs that show link or activity status, while the TL-SG105 adds port-based 802.1p/DSCP quality of service and IGMP snooping. These features are more relevant when a network carries voice, video, or other traffic where consistent prioritization is useful. For basic file sharing and internet access, plug-and-play operation may be the only requirement.
Check Included Accessories
Accessories can determine how quickly a splitter is useful. The TP-Link one-to-two model includes both a USB-C power cable and a Cat5e Ethernet cable. The LIEZHUA one-to-four includes a Cat6 LAN cable, and the one-to-two model with Cat6 cable likewise provides a usable network lead. Other products include a power cable but do not identify a network cable as part of the package.
Consider Size and Portability
A compact splitter can be tucked behind a television, placed beside a laptop dock, or carried in a travel bag. Aluminum housings provide a more durable feel, while lightweight plastic may be easier to transport. The TL-SG105 uses a desktop or wall-mountable metal enclosure, so it requires more deliberate placement than the smallest inline adapters.
How to Use and Care for Your Internet Splitter
Begin by identifying the source Ethernet connection, such as a router port, modem connection, wall jack, or an existing switch. Connect that source to the splitter's single input with a suitable Ethernet cable. If the product requires external power, connect its USB lead to the recommended 5V source before attaching endpoint devices. This order helps the adapter recognize its upstream link more reliably.
After the source and power are connected, attach Ethernet cables to the desired output ports. The attached devices should normally be configured to obtain an address automatically, just as they would when connected directly to a router or switch. Do not install extra drivers unless the manufacturer specifically requests them. Use the LEDs, where present, to confirm active links and troubleshoot loose or inactive cables.
Keep the splitter uncovered, away from moisture, direct heat, and crushing pressure. For a permanent installation, secure the upstream and output cables without creating tight bends. Clean the enclosure with a dry or lightly damp cloth, and avoid pushing debris into the RJ45 sockets. Periodically check the power connection and cable seating, especially if a previously working device loses its network link.
Frequently Asked Questions
Does an internet splitter double my internet speed?
No. A splitter usually divides one upstream Ethernet connection among multiple outputs. The total available bandwidth remains constrained by the source connection, so simultaneous users may each receive less than the full advertised speed. A multiport network switch is generally better for a busy network, while a splitter is convenient when only one source port is available.
Can I use an Ethernet splitter without power?
Most compact splitters in this roundup require a USB power connection and will not operate without it. The TL-SG105 is a self-powered conventional switch and does not need an external USB supply. Always follow the specific product instructions, especially if the listing states that a stable wall adapter is recommended.
What is the difference between an Ethernet splitter and a switch?
An inline splitter takes one incoming Ethernet connection and provides two or more outputs through a compact powered adapter. A switch offers several full-size RJ45 ports and is designed as a central connection point for a network. A switch generally offers a more familiar and scalable architecture, while a splitter is useful for compact expansion where a new cable run is inconvenient.
Can I connect two computers to one internet splitter?
Yes, the one-to-two models can connect two Ethernet-enabled computers or other RJ45 devices simultaneously. Both devices will share the upstream bandwidth and normally obtain network settings automatically. If both require heavy downloads at the same time, expect each to receive a portion of the available connection rather than a dedicated full-speed line.
Will an internet splitter work with Cat8 Ethernet cables?
Every featured one-to-four or one-to-two splitter lists compatibility with high-category wiring, generally Cat5 through Cat8, although the exact support varies by model. The entire path must support the intended rate, including the source device, switch, endpoint, and installed cable. A newer cable alone cannot raise the speed of an older router or network device.
How many Ethernet devices can I connect at once?
The featured inline splitters provide two, three, or four simultaneous output connections. The TP-Link TL-SG105 provides five Gigabit switch ports, one of which normally connects to the router or upstream network. The number of usable connections also depends on compatible source equipment, cable quality, and whether the network is operating as intended.
Do Ethernet splitters require drivers or configuration?
No. The products featured here are designed primarily for plug-and-play use. Once the upstream Ethernet line and required power are connected, endpoint devices should use their normal automatic network settings. Advanced switching features on the TL-SG105 are also available without software installation, although the device remains an unmanaged switch.
Can I use an internet splitter with a modem?
It depends on the splitter and the modem's connection method. A splitter is most commonly placed between a router's Ethernet port and connected devices. Some compact models may also work with compatible ADSL or modem equipment, but one product specifically advises contacting technical support before use with a modem. Confirm compatibility when in doubt.
Final Thoughts on Choosing the Best Internet Splitter
The TP-Link TL-SG105 is the strongest all-around choice for a permanent wired network because it offers five Gigabit ports, useful traffic features, easy setup, and a highly compact metal enclosure. The TP-Link one-to-two splitter is the better pick for a true inline adapter with an included Ethernet cable, while the UGREEN model leads the premium two-port category with a refined aluminum design.
Prioritize the number of outputs, the availability of reliable power, and the reality of shared bandwidth before choosing a compact model. A two-port splitter is ideal for a small media center or workstation, while three- and four-output versions help when several devices must use one source line. For high traffic, multiple users, or long-term expansion, a multiport network switch is generally the more robust architecture.
Check the current product listing, included accessories, cable support, and power requirements immediately before purchasing. Ratings and product details can change, and pricing varies by retailer and time. Once those final details are confirmed, the right internet splitter can provide a simple, effective way to make better use of an available Ethernet connection.
