How To Connect To An Ethernet Cable

Connect your computer to your router by using an Ethernet cable. Ethernet cables are also called RJ-45s, CAT5s, or CAT6s.

Ethernet Connection

The Ethernet protocol connects computers with other network devices in a physical space. A local area network (LAN) is a way for computers and other devices to share files and information. An Ethernet network allows computers and other devices to efficiently share information and files.

Following the Windows 10 Creators Update or Windows 10 Fall Creators Update, your laptop or desktop may fail to boot up due to the Ethernet not working issue. Every time you update your Windows to the latest version (v1730 or v1729), you may encounter the no Ethernet connection or other network problems, such as unidentified network problems, secure Internet or no WiFi available problems.

Windows 10 Creators Update or Windows 10 Fall Creators Update can cause your Ethernet connection to fail when you boot your laptop or desktop computer. As a result of upgrading Windows to the latest version (v1730 or v1709), you may encounter problems with your Ethernet connection, as well as other network issues like an unidentified network connection, an Internet, backup, and WiFi connection issue.

Hardwire Internet

In contrast to wireless internet, hard wired internet is used to connect your device to an access point using ethernet cables rather than WiFi capabilities built into your router.

Ethernet Drivers

In order for Realtek Ethernet cards to communicate with Windows PCs, the Realtek Ethernet Drivers must be installed.

Checking the Ethernet cable if the issue is only with an Ethernet connection is the first thing you should do if your WiFi is working fine. If you see any signs of damage, we recommend you replace the cable with a new one if you find that the Ethernet cable is not properly plugged into the router and the computer.

It’s impossible to conduct your daily office work without a network connection. However, you don’t need to worry too much about it. On your Windows 10 Creators Update/Fall Creators Update computer, you will find solutions to the “No Ethernet connection” or “Ethernet not working” issue.

Why is the Ethernet connection not working in Windows 10?

Why is the Ethernet connection not working in Windows 10?

Ethernet Cable In Laptop

If you want your laptop to connect via Ethernet cable without having to worry about anything, you’ll probably need a basic USB-A to Ethernet adapter. Currently, most laptops have at least one USB-A port, and they will likely remain so until the year 2022. They are inexpensive, small, and easily accessible.

Cable Connected

You can use Ethernet cables primarily to connect WiFi routers, modems, TVs, computers, telephone lines, and other devices that require an internet connection.

It may be due to one of several reasons that Ethernet isn’t working on your Windows 10 PC. Ethernet issues can stem from Ethernet cable issues, port problems, problems with Ethernet drivers, or settings in Windows itself.

Ethernet Not Working But Wifi Is

If your Ethernet is not working while your Wi-Fi is working, a poor connection between your router and your computer is most likely to blame.

You may also be experiencing Ethernet incompatibility with Windows 10 if your computer’s antivirus program is the culprit.

The primary cause of the non-functioning Ethernet problem is an outdated Ethernet driver, which you can update from Device Manager.

Frequently Asked Questions

If it's been a minute and it's still not working, try connecting the cable to another port on your router. If it works, then your router is defective and needs to be replaced. If it still doesn't work, you can try swapping out the Ethernet cables. You may need to borrow or buy a new cable to do this.

A broken Ethernet port in your laptop can certainly be replaced. I recommend purchasing a USB 3.0 adapter for Gigabit Ethernet. Since your laptop is only two years old, it probably has at least one USB 3.0 port. Just plug in the adapter and you're all set.

Expand Network Adapters, then right-click on the Ethernet device and select Enable. Restart your computer to save your changes, and check again to see if you've successfully fixed the problem of your Ethernet not working in Windows 10. If not, go to Device Manager again, right-click on the Ethernet device, and select Update Driver.
