Why Ethernet on Windows 10 is slower than Wi-Fi

Since an Ethernet connection is a connected connection and nothing is in the way of your router and your device, it is theoretically quicker than a WiFi connection.

WiFi, however, is wireless. Because it connects by radio waves, solid barriers absorb and block it. Additionally, interference from other networks causes a severe slowdown.

Therefore, something is clearly wrong and needs to be repaired if you experience slower internet through ethernet than through WiFi on Windows 10.

You will be aware of exactly what to do to permanently resolve this issue after reading this explanation of the cause of your ethernet’s slowness in Windows 10 and the repair.

Let’s start!

Which Is Better: WiFi or Ethernet?

To further help you comprehend the seriousness of your problem, this section covers ethernet and WiFi properties and how they are supposed to operate.

Both Ethernet and WiFi offer advantages and disadvantages in terms of disruption, latency, interference, etc.

The following are the main distinctions between Ethernet and WiFi:

Speed & Data Transfer Rate

Ethernet can transfer data at a rate of 1000 Mbps. The data transfer rate of the most recent Wi-Fi standard, however, is 1300 Mbps.

Even if WiFi is quicker than ethernet, if it is unreliable, this advantage is irrelevant.

Reliability

By-passed by walls and things, WiFi is absorbed. Additionally, interference from other networks significantly slows it down. Ethernet, in contrast, isn’t obstructed by anything. It is more dependable than WiFi and offers a constant speed.

Latency

The reason is the lag in internet traffic reaching your device. Due of its increased latency, WiFi falls short of ethernet in the latency department.

Security

Which is more safe, an enclosed network like ethernet or an open network like WiFi?

Since WiFi is more difficult to secure than ethernet, it also loses at the security factor.

Accessibility

Finally, WiFi triumphs over ethernet since it is more accessible and has an easier installation procedure.

Why Is My Ethernet on Windows 10 Slower Than WiFi?

You should be aware that ethernet shouldn’t be slower than WiFi based on the preceding section.

However, imagine that even while connected over ethernet, your internet is experiencing delays. In that instance, it may occur as a result of NIC restrictions, incorrect router configuration, software or operating system issues, VPN use, or the use of subpar cables.

Ethernet is slower than WiFi in Windows 10 for the following reasons:

Extra-Long Cable Length

For Cat5 or Cat6 cables, the maximum cable length is 328 feet, or 100 metres. Your connection will be slower the longer the wire is.

Poor wiring

Your internet connection may suffer if your cable is of poor quality. If your computer is linked to a cable that is faulty, has loose ends, or is cramping up, you’ll experience problems with internet connectivity.

Radio wave interference

Even though interference is not a significant problem for Ethernet, it is still a problem. Interference can be brought on by speakers, microwaves, or fluorescent lights. Your internet will operate more slowly if the Ethernet cable is kept close by.

The computer could have a virus.

Your computer has been infected with a virus or spyware, which is the source of your issue. It compiles all of the data related to your online actions.

Issues with ISP

Your Internet Service Provider (ISP) may be totally to blame for the problem if there are issues with an underground or above-ground cable system, or for other reasons unrelated to your hardware or software.

How can I resolve Windows 10’s slow Ethernet issue?

The first thing to attempt to remedy the slower ethernet internet speed compared to WiFi is to restart your computer, network adapter, and router; try a new port on your router; scan your PC; and change the ethernet cable.

If they weren’t helpful, don’t worry; I’ve included every option that will unquestionably resolve the problem below.

To improve ethernet performance on Windows 10, follow these steps:

Thoroughly test

Run a speed test while connected to WiFi on your smartphone. After noting the speed, switch off WiFi completely and conduct the same speed test with the device connected via ethernet. Then, compare the results.

Rerun the speed test after connecting ethernet to a different device.

This will enable you to identify the issue’s root cause. Is it the hardware or software of your device, your ISP, your Ethernet cable, or something else?

Switch to Another Port

You’ll have a shaky connection and fall short of the expected internet speed if the port is broken. Your router should have numerous ports. Try a different port and see if the issue is resolved.

Use an Alternative Cable

Your internet speed might be drastically decreased by an outdated, poor-quality cable. Verify that the wires are not crowded close together. Use long cables instead since small cords flex more.

Cable should be Cat6 or Cat8. They have the ability to transmit data at a rapid rate.

The network drivers must be updated

You should maintain these drivers updated because they interact with the router and can sometimes lead to issues like the one at hand.

The steps to upgrade network drivers are as follows:
  • Select Device Manager by performing a right-click on the Windows icon.
  • Network adapters, expand
  • Select Update driver by doing a right-click on each network adapter.
  • Select Find drivers automatically by clicking.
  • Repeat this procedure for each network adapter.

Router reset

Resetting the router will restore all of your settings if you unintentionally modified any of them.

How to reset a router is as follows:
  • Go to 192.168.0.1 in your browser once it is open.
  • Log in using your chosen Username and Password. Check your router’s login information if you haven’t already if any aren’t set.
  • Reset the router by going to the Settings page.
  • Complete the activation process for the router.

Turning on and off network adapters

Any temporary problems or bugs causing slow internet through Ethernet can be fixed by resetting the network adapters.

The steps to reset network adapters are as follows:

Select Device Manager by performing a right-click on the Windows icon.

  • Network adapters, expand
  • Disable device by doing a right-click on each network adapter.
  • To confirm your selection, click Yes.
  • The same adapter, then select Enable device from the context menu.
  • Repeat this procedure for each network adapter.

Relocate the Ethernet cable to avoid interference

Even while interference is not a major issue for Ethernet, it is nevertheless a problem. Interference can be brought on by speakers, microwaves, or fluorescent lights. The internet can be slowed down, especially by microwave ovens, which generate a lot of electromagnetic interference.

A minimum of 10 feet should separate your ethernet cable from these electromagnetic sources.

Check for malware or viruses

If your computer is being attacked by a virus or other malware, it may result in slow internet through Ethernet. Completely scan for and get rid of any malware or viruses.

This is how to perform a complete scan on Windows 10:
  • Select Windows Security from the hidden taskbar icons.
