Ethernet vs. WiFi- When to Use Router Ethernet Cables for Optimal Performance

Ethernet and WiFi are widely used in today’s world for connecting devices to the internet. Each technology has its advantages and disadvantages, and the best choice for any given situation will depend on a number of factors, such as:

The distance between the device and the router

The amount of data that will be transferred

The level of reliability that is required

The cost of the equipment

Speed and Reliability

Ethernet is typically faster and more reliable than WiFi, as it uses a physical cable to connect the device to the router. This means that there is less chance of interference from other devices or objects, and the data transfer rate is more consistent. If you need a reliable connection for a device that is used for streaming videos or playing online games, Ethernet is the better choice.


Ethernet cables can be used to connect devices that are located relatively far apart from the router, while WiFi has a more limited range. If you need to connect a device that is located in a different room or on a different floor, Ethernet is the better choice.


Ethernet equipment is generally less expensive than WiFi equipment, making it a more cost-effective option for large or complex networks.

Ease of installation

Ethernet cables are relatively easy to install, as they only need to be plugged into the device and the router. WiFi, on the other hand, requires a more complex setup, as it involves configuring the router and the connected devices.


Ethernet is generally more secure than WiFi, as the physical cable connection makes it more difficult for unauthorized users to access the network. If you need a high level of security, Ethernet is the better choice.


When choosing between Ethernet and WiFi, you need to consider a number of factors, such as the speed, reliability, distance, cost, ease of installation, and security requirements. Ethernet is typically the better choice for devices that require a high level of speed, reliability, or security, or that are located a significant distance from the router. WiFi is a better choice for devices that need a more portable connection or for situations where it is not possible to run Ethernet cables.
