Check whether Ethernet Port is loose

Yes, even the Ethernet port can be loose, if you connect disconnect the Ethernet cable more frequently. Almost every motherboard and Windows 10 laptop come with an Ethernet port aka RJ45 port. And, usually, laptop users face this problem. If you notice, when you connect the ethernet cable to your laptop or even PC, a white/yellow LED turns on. This LED is to indicate that the Ethernet connection is working properly.

Though, if this LED blinks sometimes, or gets turned off, then the Ethernet port is loose or got malfunctioned. Well, you can use a USB-to-Ethernet Adapter, if you find the Ethernet port is damaged.

Do check Ethernet port is dust-free or not. Sometimes, alien material like dust, debris can cause connection interference. You can use a small brush or air blower to clean the port. To be sure about the Ethernet port, you should try using a new Ethernet cable. Well, in some scenarios, the router ethernet port also can be the culprit. And, as you might know, these days router comes with multiple ethernet ports, so try switching that as well.

 

Change Ethernet Cable

Well, not always LAN port could be the culprit. If you’re using a cheap or damaged Ethernet cable, then this can be the cause of the ethernet keeps disconnecting. Using a counterfeit Ethernet/LAN cable also can affect the connection performance.

If you have a new LAN cable lying around, then try using it. Or, you can use your existing LAN cable on a different computer. If the cable works well, which means the connection stays stable, then the issue might be from the software side.
