9 Reasons Ethernet Slower Than Wi-Fi? [15 Solutions]

Before getting to the answer of why is my ethernet slower than Wi-Fi? Let’s understand them. Both ethernet and the internet are sources of transferring data from one place to other, but the way they do that is different from each other.

The problem some people face is that sometimes ethernet gets slower than their Wi-Fi connection due to some reasons.

If you face the same problem and search to resolve this, congratulations, you are at the right place.

In this article, we have discussed the almost nine most important reasons why ethernet gets slow.

We have also discussed the almost 15 most important and easy solutions by which you can resolve this issue quickly.

So let’s explore the Aishideas.

Difference Between a Wi-Fi and Ethernet connection

1Ethernet connections connect devices to a network or the Internet through an ethernet cable.A Wi-Fi connection allows users to connect to a network and the Internet without wires by connecting to a Wi-Fi router via a wireless connection.
2The widely used Packet Switched LAN technology is also known as Ethernet.Wi-Fi is defined by IEEE 802.11x standards, with x denoting different Wi-Fi versions.
3There is no mobility with Ethernet because it necessitates a lot of cabling.Wi-Fi eliminates the need for cables, and without wires, there are no ports.
4It isn’t adaptable by nature.Its nature is adaptable.
5It has a significantly faster data rate and is more eco-friendly.It provides movement and flexibility, but it has a slower response time and is less efficient in comparison.
6It’s time-consuming and tough to set up.It’s simple to set up and use.
7Over Ethernet, data transmission does not need to be encrypted.Data is encrypted and sent over a wireless network.
Difference between Ethernet and Wi-Fi


A wired connection is far more secure than a wireless one. Data on an Ethernet network can only be accessed by physically connecting a device.

In contrast, data on a Wi-Fi network is transmitted over the air and can be intercepted more readily.


Electrical appliances or tangible components obstructing the signal are more likely to interfere with a Wi-Fi connection

As a result, an Ethernet connection is more reliable since it is immune to interference and resonance, unaffected by physical objects’ presence.

The Data Transfer Rate and Speed

While several factors influence the actual speed of a Wi-Fi and Ethernet connection, ethernet is always faster. 

Today’s highest Ethernet speeds are 10 Gigabits per second or greater, while the fastest Wi-Fi rates are theoretically 6.9 Gigabits per second; however actual speeds are typically less than 1 Gigabit per second.


An Ethernet connection is unquestionably more problematic than Wi-Fi. Users can roam freely throughout a site using Wi-Fi.


When considering connection speed and quality, you must also examine latency.

Communication to the device is interrupted as a result of latency. The latency of Wi-Fi is higher than that of ethernet.

Reasons Why is My Ethernet Slower Than Wi-Fi

Reasons why ethernet slower than wifi

We often take networking for granted since wireless communication, sometimes known as Wi-Fi, has made it convenient.

However, if you want the fastest speed, you know that utilizing an Ethernet connection to connect your device to your Local Area Network (LAN) is the ideal option.

But what if ethernet gets slower than Wi-Fi?

Take heart, even if such a situation can be frustrating or downright infuriating.

Here is why is my ethernet slower than Wi-Fi and what one can do about it.

NIC Limitations is Causing Ethernet Slower than Wi-Fi

NIC limitations can answer why my ethernet is slower than Wi-Fi. If all software and driver options have been exhausted, the network adapter itself may be the source of the problem.

This does not necessarily involve your Ethernet adapter malfunctioning.

Your NIC’s capabilities may be limited. This may hint out why my ethernet is slower than Wi-Fi.

10 Mbps, 100 Mbps, 1,000 Mbps (sometimes known as 1 Gbps, or 1 Gbps), and 10,000 Mbps are the different speeds of network adapters.

If your card’s maximum speed is less than 100 Mbps, your Wi-Fi is certainly exceeding your ethernet. It will cause ethernet slower than wi-Fi.

802.11n, or Wi-Fi 4, is a Wi-Fi standard that has been around since 2006 and offers a theoretical maximum throughput of 450 Mbps.

The 802.11ac (Wi-Fi 5) standard, released in 2013, has a maximum speed of 1300 Mbps.

(Not to mention 802.11ax, which will be available in 2021.)

As a result, if your device was made after 2006, the chances are good that your Wi-Fi card is compatible with 802.11n or above.

Keep in mind that these throughput figures are hypothetical, and only a device operating under ideal conditions could accomplish them.

Nonetheless, with a theoretical maximum speed of 450 Mbps, you’ll easily exceed the 100-meg barrier.

  Your VPN Is Causing Ethernet Slower than Wi-Fi

Do you utilize a virtual private network (VPN)?

Tunneling is used in a Virtual Private Network to provide a secure connection to another network.

Many work-from-home scenarios necessitate VPNs to connect to business networks, and VPNs have grown popular among security-conscious internet users.

VPN can help you find out why my ethernet is slower than Wi-Fi. VPNs always slow down your connection because they require some overhead to establish a secure connection.

Why would this affect your hardwired connection but not your Wi-Fi connection?

The VPN may only use your NIC connection rather than your Wi-Fi.

Disable your VPN and perform another speed test on both Ethernet and Wi-Fi to see how it affects network performance.

Length Is Causing Ethernet Slower than Wi-Fi

Why is my ethernet slower than Wi-Fi? This question can lead you to find out the cable length. If we consider the cable length, the Cat5 cable should be 328 feet or 100 meters long as a standard length. 

All the wires, Cat5, Cat5e, Cat6, and Cat6a, are the same length. If your cable is longer than the industry standard, choose a shorter one.

Cabling Is Causing Ethernet Slower than Wi-Fi

Poor cabling can help you find out why my ethernet is slower than Wi-Fi. A poor cable selection might lead to concerns such as slow internet. 

Prepare to experience slower internet connectivity if you have an incorrectly or inadequately crimped cable, loose ends, or have the wrong sort of cable attached to your PC.

Cat5e cabling is the industry standard for a better ethernet connection.
