How to Fix: Ethernet cable keeps disconnecting and reconnecting [Windows 10]

Daily life has become almost entirely dependent on the internet; the most preferred mode is Wi-Fi to access the internet. However, the Ethernet connection has proven to be more stable than the wireless one.

Occasionally, we face some malfunction with our network connection on Windows 10. If you are facing problems with your internet connection, such as ‘unidentified network’ or ‘Network Disconnected,’ there could be more than one reason for this problem.

One of the most commonly neglected problems is- a faulty Ethernet connection.

What is an Ethernet cable?

Ethernet cables are used to provide an internet connection; these are used to connect devices to a local network. For example, ethernet cables are commonly used to connect a Wi-Fi router or a modem to the Ethernet port behind the computer or telephone line.

The Ethernet cable is also known as the LAN cable, and the Ethernet port is also called the LAN port.

Types of Ethernet cables

The twisted pair, twin axial, and backplane are all Ethernet cable types. New enhancements to these have been introduced, known as the Energy Efficient Ethernet (EEE); they have similar threads that reduce power usage during low data usage.

They aim to reduce power consumption by over 50% while retaining the compatibility of the existing equipment.

Some companies use this technology to reduce power consumption for Ethernet, using the name Green Ethernet or Green Energy.

Along with saving power, Green Ethernet backs off the transmit power on a shorter cable run, reduces alien material, and improves the connection performance.

The ethernet keeps disconnecting- How to fix it?

In case the Ethernet connection is causing trouble with your network connection, or If you feel the Ethernet connection keeps disconnecting, Let us look at some solutions for this problem.

Solution#1- Check and replace the Ethernet cable.

  1. First and foremost, let us check the hardware of our PC. Check the connection of the Ethernet cables to the CPU, the modem, the router, and the telephone line. Make sure they are correctly connected to the Ethernet port.
  2. Secondly, We need to check for any damaged cables, cuts, or broken wires that can disrupt the network connection.
  3. Next, you can remove and reconnect all the Ethernet cables to the multiple Ethernet ports behind the CPU. Or connect the cables to a different computer, router, or port to check if the problem persists. Let’s move on to the next one if this cannot establish a stable connection.
  4. Now, let us try using a different Ethernet cable. Unfortunately, even though these cables are durable, they are likely to go wrong.

Other minor checks should be done, like cleaning any dust from the Ethernet port of the device. Some dust or residue may cause connection interference. You should also ensure the cables are not tangled and nothing heavy is sitting on the Ethernet cables.

The above solutions are hardware-related, and the problem with the Ethernet keeps disconnecting will be solved. However, consider the following solutions if facing the same Ethernet connection issue.
