Although those two devices do need to share the overall connection speed of the Ethernet cable that runs between the router and the switch, it’s still far more reliable and stable than Wi-Fi which could see the two devices competing for frequency as much as bandwidth. Although connecting to a router will give you internet access too, that will also give you network access to any wireless devices, like smartphones and tablets, that use the Wi-Fi network for their internet and network connectivity. Consider an Ethernet Adapter Most Ethernet splitters work by taking an input signal and dividing it into multiple output signals. On a two-way splitter, each output has half the normal strength as the signal is divided by two. But this is not how Ethernet signals work.
Ethernet splitters are not mini-hubs. They are specifically designed to split a single connection with four twisted pairs into two connections with two distinct twisted pairs. Fortunately, in most cases, laptops that have exclusively USB-C connections, like several of Apple’s latest generation MacBooks, actually use Thunderbolt or USB4 ports, which provide enough bandwidth for even the fastest of Ethernet connections; You just need the right adapter for the job. Maximum Ethernet Switch speed without the clutter Connecting an Ethernet cable doesn’t immediately mean you have access to the internet. The other end has to be connected to an internet-connected router or modem to do that. However, whether you’re online or not, being connected to the local network gives you the ability to connect to any other system on the network. This is ideal for playing localized games, for high-speed file sharing, or for accessing network-attached printers, scanners, and other devices where wireless connectivity is not possible, or desirable. Another downside is that you need a splitter at each end of the main cable. So a splitter doesn’t save you any ports on the router; it still takes up two ports. Every ethernet network connects terminals via a splitter, so to speak. A splitter is just a parallel configuration of devices.All ethernet devices on one network are connected together, in this simplest way. All terminals must be connected to the same network wire. Downgrading to 100Mbit is expected behaviour (DO use a true 100Mbit switch in a permanent installation, you want something that auto-negotiates to 100FDX (100 Mb full duplex), a gigabit switch configured to 100Mbit usually will not, leaving other devices confused) - if it DOESN'T something is odd, either all devices on that cable support 1000BASE-TX -- which can work on two wires but needs even higher grade cable, and is uncommon in most equipment. Any cable you connect to the splitter will count towards your total cable length. However, since a splitter has 2 physical connections, you have two cable lengths instead of just one. Theoretically, splitters don't amplify signals so your maximum cable length will not be extended.
You still need 2 free ports on your existing switch/router. Switches/routers only provide one connection per port. Trying to use a splitter to turn one connection into two won't work since that's the job of switches/hubs which clearly, a splitter is not either of. If you attempt to use this two turn one connection into two, I see two possible scenarios: Only one device will receive a connection, or, the port on the switch/router will fail to work properly with both devices connected. The setup for this device is a little more complicated than using a simple Ethernet splitter and it's not recommended for Power over Ethernet (PoE) applications. It also has the caveat of only supporting up to 100 Mbps connection speeds, so it will not be able to take full advantage of Gigabit or faster Ethernet networks.

The only reason to do this is if you really need two different physical connections and only have one cable. It is an emergency kludge. At least one cable/connection is out of spec. It is not compatible with Gigabit. It is not guaranteed to work (though if you drop to 10Mbit it often will). You may also like this: Router VS Switch: What Is the Difference Between Them? How Does Ethernet Splitter Work To get around that problem, you can use an Ethernet splitter, or rather, an Ethernet switch. These devices can take a singular incoming Ethernet connection and make it accessible to multiple users at the same time. This not only expands the number of available Ethernet connections for waiting devices but makes running the Ethernet cable much easier since you needn’t have multiple cables going around doors and through walls: just run one cable, with a splitter on the end.
