How to connect two devices to one ethernet port?

Do you have an ethernet port and looking to connect two devices to the same? There are two options through which you can connect two devices to one Ethernet port.

Method 1: Using Ethernet switch/adapter/hub

To connect two devices to one Ethernet port, you need:

  • An Ethernet switch/ ethernet adapter
  • An RJ45 Cat 6 Ethernet cable
  • USB to Ethernet cable connector

Step 1: find an Ethernet switch

An ethernet switch or adapter is like the hub of many Ethernet ports into one. It has a USB C port at one end. This USB C port connects it to a laptop. Another end, i.e., the Ethernet port hub, allows you to connect your Ethernet using an Ethernet cable.

Step 2: Connect other devices to it

You now need to connect other devices to the Ethernet adapter/switch. For this, you will need an Ethernet cable. If your laptop/device has an Ethernet port, you can directly connect your laptop to the ethernet switch.

If the device/laptop doesn’t have an Ethernet port, you need to buy a USB to Ethernet cable. You connect one end of the Ethernet cable to the Ethernet port on the Ethernet switch and another end, i.e., the USB, to the laptop/device.

However, in this method, the connected laptop has to stay functional, i.e. the laptop you connected your hub to in step 1. If the laptop turns into sleep mode, all the other devices connected to it will lose the network connection.

Method 2: Using Ethernet splitter

If you want to only two devices to one Ethernet port, you can also use an Ethernet splitter. To connect two devices to a single Ethernet port, you will need

  • Ethernet splitter with cable
  • USB to Ethernet cable convertor
RJ45 Ethernet Splitter

When buying an Ethernet splitter, make sure it has a cable that will allow you to connect it to the Ethernet port. The cable has an RJ45 port at one end.

To make the connection work, you need first to use the one end of the Ethernet splitter and connect it to your Ethernet port.

Use a USB to Ethernet cable converter now. Use one end of the converter i.e., the Ethernet port side, to connect it to the Ethernet splitter. You will need two USB to Ethernet cable converters if you want to connect two devices. Use the other end of the converter i.e. USB to connect it to your device like a laptop.

Using this, you can connect two devices to one Ethernet port.

Will the Ethernet splitter slow down the connection?

It is a common question when using an Ethernet splitter. The answer is no. Ethernet splitters do not slow down the connection if your internet connection has a speed of 100mbps or more. If your router provides 1 Gbps speed, it may diminish it to 100mpbs, thus making the speed slower. Ethernet splitters work best for general use and allow you to conveniently connect 2 devices to one Ethernet port.


Do you lose speed with an Ethernet splitter?

To answer, no, the splitters will not slow down the connection if they are utilized in a 100Mbps network. However, if your router can deliver 1Gbps and you put a splitter in the middle, the bandwidth will be limited to 100Mbps. The splitters did restrict the speed in this case, and the connection will be slower.

Do Ethernet couplers reduce speed?

Ethernet couplers don’t lower speed. They can cause more defective packets if the cable length is around 100 meters. An increase in defective packets reduces throughput because of packet re-transmission, but speed remains the same. Too many errors can cause the Ethernet adapters to drop in speed.

What’s the difference between an Ethernet splitter and a switch?

The ethernet switch follows protocols, has multiple ports for power input, and needs a proper setup. Whereas, a splitter is a simple device, and it is a small extension to your current Ethernet cable that divides it into two connections.

How do I set up an ethernet splitter?

  1. Step 1: What You Need. Splitter, Ethernet cable.
  2. Step 2: Crimp the RJ45 Plug to the Ethernet Cable.
  3. Step 3: Punch Down the Other End to the RJ-45 Keystone Jacks.
  4. Step 4: Make One More Splitter.
  5. Step 5: Plug One Splitter to the RJ45 Wallplate.
  6. Step 6: Plug the Other Splitter to the Patch Panel.

Do Ethernet extenders work?

An Ethernet extender works by expanding and maximizing your Ethernet network. It is both cost-effective and efficient, as you can use copper wiring you already have. Generally, Ethernet cables can’t transmit data beyond hundred meters, but an Ethernet extender enables data transmission up to twenty kilometers.

Is there an Ethernet extender?

Ethernet Extenders, also known as LAN Extenders or Network Extenders, enable the transmission of data beyond 100m (328ft) — the general maximum cable length for copper Ethernet cables.

How do I hook up 2 computers to 1 Internet connection?

  1. Step 1 Connect to the Same Wireless Network. Make sure your router is receiving a good Internet connection via the cable modem and Ethernet cable.
  2. STEP 2 Get the Private Settings Straight.
  3. STEP 3 Get the Public and Guest Settings Straight.
  4. STEP 4 Turn on Network Sharing.

Is WiFi or Ethernet faster?

An Ethernet connection is generally faster than a WiFi connection and provides greater reliability and security.

What is the difference between CAT 5 and CAT 6?

Compared to Cat5/5e cables, Cat6 cables have stricter performance specifications and significantly higher data transfer speeds at greater distances. They are more tightly wound than Cat5 cables, and the cable conductors and cable sheath are thicker as well.

How many Ethernet cables can you connect together?

With an RJ45 coupler, you can easily connect two ethernet cables together, but it isn’t always the best idea for a couple of reasons, including the degradation of not only the cable itself but also the strength of the connection.

Do I need an ethernet splitter or a switch?

Both switches and Ethernet splitters are primarily used for connecting different computers or other networking devices. However, switches can work standalone or in a group via stacking or clustering, while Ethernet splitters need to be used in pairs.

What is a smart Ethernet switch?

Web smart switches—sometimes called smart switches or Web managed switches—have become a popular option for mid-sized networks that require management. They offer access to switch management features such as port monitoring, link aggregation, and VPN through a simple Web interface via an embedded Web browser.

How can I boost my Ethernet signal?

If you are not over the noise cap, you can use an Ethernet repeater to boost your signal strength. You can also use a switch or hub to get the same effect. In any case, if noise is the issue, boosting the signal strength with a repeater, hub or switch will not help the situation.

How do I install an Ethernet extender?

Ethernet extenders are typically plug-and-play devices, so they’re easy to set up.

  1. Connect the Ethernet cable that came with your extender to an Ethernet port on your router or connection hub.
  2. Plug the other end of the Ethernet cable into the Ethernet port on the extender.
  3. Connect the extender to a power source.
