Ethernet Keeps Disconnecting (Troubleshooting Ethernet Connection)

Some people prefer wired Ethernet connection over wireless connection since Wi-Fi is less stable, and its volatile radio waves can easily get disrupted. However, wired Ethernet connection has its own fair share of issues. Sometimes, you do find your Ethernet keeps disconnecting from time to time. 

There are a number of reasons why that happens. We have done comprehensive research and come up with some possible causes and ways to fix them. Let’s get started.

Ethernet Keeps Disconnecting

Faulty Ethernet Cables

The problem with using a physical internet connection is that cables can get damaged. They can be defective at first use or get damaged or broken over time. If you suspect your Ethernet cable is causing the fault, try to connect to other ethernet ports if your computer has them. If your internet connection is okay when used with another port, that shows the last port is faulty, or there could be dirt, dust, or other debris in it.

Refresh Router Firmware

Sometimes, your router could be the source of your Ethernet keeps disconnecting issue. A router usually comes with firmware, and for a small fee, you’ll regularly get the firmware updated to the latest version.
