Inherently, Ethernet cables pass data through physical wires, which means that they are far less susceptible to interference by other electronic devices or environmental factors, such as walls and obstructions, that can distort the data signal. This reliability makes the internet connection more stable, allowing for uninterrupted video streaming or online gaming, for example. So, while an Ethernet connection appears to be the better choice when compared to WiFi reliability, do bear in mind that WiFi offers unparalleled convenience and users should weigh the trade-offs, which will be discussed below.
• Speed: Ethernet offers a connection with higher speeds compared to WiFi. Whereas WiFi speeds depend on factors such as the strength of the signal and network, Ethernet provides dedicated bandwidth, making it possible to get data transfer rates that are significantly higher. For internet activities like high speed downloading or high quality streaming (e.g., HD), Ethernet is the ideal approach. When comparing Ethernet and WiFi connections, the key difference between speed becomes evident, with Ethernet offering faster and more consistent data transfer rates compared to WiFi.
• Security: While WiFi networks have evolved to enhance security measures, it’s essential to consider the differences in WiFi security compared to Ethernet connections. Wired Ethernet connections are usually taken to be a safer alternative to WiFi connections. The main advantage of Ethernet when compared to WiFi is that the bridled access using cables makes it considerably more difficult for unauthorized users to hack into a network. Having an advanced level of protection presents a high degree of safety, especially for business people or individuals who share confidential data. 
• Less Interference: Different WiFi signals can overlap or compete with others, causing interference from neighboring networks or electronic devices. Ethernet cables do not face these problems and are not influenced by nearby networks. Such an interference-free environment, especially in situations when various WiFi networks operate at the same time, enables an improvement of network quality for each WiFi user.

Why should you choose WiFi?

WiFi, or wireless connection, offers convenience and flexibility, making it a popular choice for many users. Here are some reasons why WiFi might be the preferred option:

• Mobility: WiFi connects users to the internet without the need for wires or cables anchored to a particular spot. This enables seamless internet access from any location within the wireless network’s coverage area. This mobility is especially beneficial for users of mobile devices like smartphones, laptops, and tablets, allowing them to surf the web or access online resources without being tethered to a specific spot. 
• Ease of Installation: Installing a WiFi network is logically easier, and the convenience of this is more preferable for many people compared to laying Ethernet cabling around a building. The absence of physical cables eliminates the need for complex installation procedures, reducing time and effort spent on network deployment. This ease of installation is advantageous for homes, businesses, and public spaces seeking to establish internet connectivity quickly and efficiently. Additionally, the plug-and-play nature of WiFi routers makes them accessible with minimal technical expertise, further streamlining the setup process. 
• Cost-Effectiveness: WiFi connectivity doesn’t require the need for costly Ethernet cables and infrastructure. This makes the technology an economical solution, especially for small home offices, startups, and businesses operating on a tight budget. Furthermore, WiFi routers are typically cheaper than Ethernet switches or hubs, making them accessible to a broader range of users.
• Scalability: WiFi networks excel in accommodating a growing number of connected devices without the constraints of physical wiring. This scalability is particularly advantageous in environments characterized by fluctuating demands, such as public venues, offices, and cafes. As the number of connected devices increase, WiFi networks can adapt to meet the rising demand, providing reliable internet access to users without the need for additional wiring or infrastructure upgrades.

Ethernet vs. WiFi: Other Factors to Consider

Reliability, speed, security, and convenience are crucial considerations when choosing between WiFi and Ethernet. As identified above, these two connections vary from one type to another with regard to their advantages and disadvantages, thereby making one more suitable to a situation or environment over the other. Several factors should be considered which may influence your decision between the two: 

Physical Infrastructure

• Ethernet: Cabling infrastructure for Ethernet connections may not be the best option where it would be either not feasible or impractical. It could be extremely manual work to pull Ethernet cables along walls and ceilings, even more so if it comes to the point that it can be impossible to do that in rental spaces and older buildings. In this case, users may consider the option of cable internet alongside Ethernet and WiFi connections, particularly in areas where wired solutions are preferred but Ethernet installation is impractical.
• WiFi: On the other hand, wireless networks operate with WiFi signals and never require any physical infrastructure, other than a router or an access point. Therefore, a WiFi connection makes it more convenient for homes, offices, hotels, and similar premises, where laying cables is cumbersome or an impossibility.

Distance

• Ethernet: Ethernet cables have a limited reach normally only to 100 meters (or 328 feet), unless they are used with signal repeaters and extenders. When it comes to devices that are far off or separated between distinct spaces, Ethernet may not be the most cost-effective way to achieve the same results without having Ethernet cables in between.
• WiFi: When an area is covered by WiFi signals, the area will generally be much bigger and will depend on the range of the router and its signal strength. This is primarily why a wireless connection offers the best option for covering large distances, as there isn’t a need for wires to physically connect devices in the home or office. 

Interference

• Ethernet: Ethernet cables provide a reliable and stable connection that remains immune to interference from external sources. Unlike WiFi signals, Ethernet cables transmit data through physical wires, ensuring high-quality performance, even in densely populated areas with numerous electronic devices.
• WiFi: While convenient for their wireless nature, WiFi signals may encounter interference from various sources, including obstacles and neighboring networks operating on the same frequency. Electronic equipment, walls, furniture, and other physical barriers can attenuate WiFi signals, leading to signal degradation and reduced performance. Additionally, in densely populated areas with multiple WiFi networks in close proximity, signal congestion can occur, impacting WiFi performance.

Latency

• Ethernet: Wired systems, such as Ethernet, usually display lower latencies due to their superiority on behalf of applications that require immediate responses. When people take part in different online environments, including gaming, video conferencing, and VoIP calls, a slight period of delay may worsen enjoyment and productivity.
• WiFi: In contrast to WiFi, Ethernet has higher latency because of its connection’s barriers, such as signal and network interference. However, for everyday situations and tasks like browsing the web or media streaming, latency is not a problem as it’s often not observable.  

Environmental Considerations

• Ethernet: Physical Ethernet cables are prone to degradation due to the impact of excessive bending, stretching, or extreme exposure to heat and water. The right installation practices are meant to reduce or even avoid these risks when installing as much as possible. However, the possibility of withstanding harsh environmental conditions is often not possible. 
• WiFi: All indoor wireless devices that are sensitive to walls, furniture, and other electrical devices can create signal interference and shorten the range of the given signal. In addition, signal coverage will be poorer where there are thick walls or structures built of concrete or metal due to the fact that the signal won’t penetrate them well. This then results in dead zones or weak signal areas.

While speed and reliability are essential factors to consider when choosing between Ethernet and WiFi, a wider range of features should also be looked at. Barriers including physical infrastructure, distance, interference, delay, and environmental problems play a significant role in choosing the type of connection you want for your situation
