Ethernet cables are an essential part of any computer setup. A loose Ethernet cable can cause a number of problems, from slow internet speeds to not being able to connect at all. This guide will teach you how to diagnose and fix a loose Ethernet cable.
Diagnose the problem
The first step in fixing the Ethernet cable is to diagnose the problem. This can be done by looking at both ends of the cable and seeing if there are any frays or cracks in the cable. If there aren’t any, then you know it’s not broken and you can move on to figuring out why it isn’t connecting.
If there are signs that the cable is broken, then it needs to be replaced with a new one.

Troubleshoot by power cycling
There are a number of reasons why you might have a loose Ethernet cable. If your internet connection is slow, it may be due to a loose cable. If your computer isn’t connecting to the internet at all, it may be due to a loose cable. You can troubleshoot by power cycling your modem and router for five minutes. This will reset the network settings and allow you to see if there was a problem with the hardware.
Check the cable connections
First, you’ll want to check the connection between your modem and your computer. Confirm that the cable is securely plugged into your modem and then your computer’s Ethernet port. If it’s not secure, try pushing the connector in more firmly.
Next, check the connection between your router and modem. The modem needs to be connected to a router for internet access. Confirm that the cable is securely plugged into both devices. It may be loose in one of these places–if so, try tightening it up by pressing the connector in more firmly.
Finally, if you’re still having problems after checking all connections, contact an IT professional for assistance.
Re-seat cables that are loose
First, check and see if the cable is loose. If you find that the cable is loose in one of the ports, re-seat it. To do this, unplug your Ethernet cable from both your modem and computer. On a wall near your computer, there will be a jack for an Ethernet port. Unplug the end with an “X” on it from this jack and plug it back in. This should secure your Ethernet cable in place and solve the problem.
Test your connection
One of the easiest ways to diagnose if your Ethernet cable is loose in the port is to test your connection. First, go to any website and see if it loads. If it does, then the cable is not loose in its port. If it doesn’t load, try restarting your computer or router. If it still doesn’t work, the cable may be loose in its port.
