How to Choose Between Ethernet or WiFi



Businesses that depend on the internet to communicate internally and connect with customers and business partners have two primary connection choices if they need a versatile, high-speed connection that can support today’s fast-paced and bandwidth-intensive internet activity—WiFi or ethernet. But how do these two internet connection types differ, and which should you choose for your company? In this article, we examine WiFi and ethernet in detail, comparing an ethernet cable and wireless connection when it comes to internet speed, reliability, latency, security features and cost-effectiveness. 

WOW’s customizable business internet plans are designed to flex and scale as your business needs change for optimal connectivity for all your mission-critical operations.  

What is the Difference Between a WiFi and Ethernet Connection? 

The difference between ethernet and WiFi is that WiFi uses a wireless connection between the device and router that doesn’t require cables, whereas an ethernet connection transmits data over an ethernet cable. 

How Does the Speed Differ Between a WiFi and Ethernet Connection?

Ethernet is usually faster than WiFi. Ethernet can be as fast as 10Gbps, whereas today’s most common WiFi technology, WiFi 6, can theoretically reach 9.6Gbps. However, actual WiFi speed is far less—around 1.3Gbps.    

How does Reliability Differ Between a WiFi and Ethernet Connection?

With WiFi, there’s a greater risk of interference due to the signal being blocked, either by physical objects or electrical devices. Ethernet connections aren’t affected by objects or electrical interference, making them more reliable. 

How do Security Features Vary Between a WiFi and Ethernet Connection?

Due to its wireless setup, a WiFi connection is more easily hacked than an ethernet network. With ethernet, a device must be physically connected to the company’s network to be a potential threat. 

Which is More Cost-Effective, WiFi or Ethernet?

Although ethernet can be more expensive than WiFi, due to wired connections between all devices, for businesses that depend on a robust, consistent, always reliable and highly secure internet connection, ethernet is seen as more cost-effective.   

The Pros and Cons of WiFi and Ethernet

You probably already have a good idea of what the “trade-offs” are between WiFi and ethernet, but here’s a more detailed assessment of the pros and cons of these two popular ways for businesses to connect to the internet.  

WiFi – Pros and Cons 

The biggest advantages of WiFi are ease of connectivity and convenience, plus the ability to connect many different types of devices in various locations. WiFi is supported by most internet-enabled devices. Another major advantage of WiFi is that you don’t need to run cables everywhere to connect individual computers and company servers. WiFi is an instant connection. However, it isn’t always reliable, and the speed you get may not be consistent. Factors that can affect WiFi speed include physical objects that may get in the way and possibly other WiFi signals from nearby companies or residents. WiFi can also experience frequent dropouts and high latency. Latency is a measure of how long it takes for data to travel to a remote server and then back to your computer. This can be especially noticeable during video conferencing. 


  • Fast and convenient to set up; automatic connections 

  • No cables needed, ideal for mobile devices 

  • Wide support by many devices 


  • Slower speeds 

  • Inconsistent connection susceptible to interference 

  • Frequently dropped signals  

For certain uses, such as emailing, web browsing and audio/video streaming, a WiFi network may suffice. And it’s faster to get up and running. However, for more bandwidth-intensive uses, like video conferencing and large file transfers, WiFi can at times be unreliable. Any interference, whether physical or electrical, can cause degraded signal quality, which leads to reduced speed and sometimes, a complete loss of the signal. If you’ve ever seen a person’s video “freeze up” while on a video conference call, this is what’s occurring.  

Ethernet – Pros and Cons 

When it comes to businesses, the major advantages of an ethernet cable system are speed, reliability and security. Even though ethernet cables must be run between offices and departments, it is a more straightforward installation, as every device is physically connected, rather than having the uncertainty of networks being “seen” by outside entities. This is why it is far more secure than a WiFi setup. However, companies must ensure that all staff computers and servers have ethernet connectors. They must also have the time and the budget to run potentially costly cables through walls and between rooms throughout the facility.  


  • Fastest speeds available 

  • Highly stable and reliable internet connection 

  • Improved data transfer speed and quality 

  • Greater security 

  • Straightforward setup 


  • Can be expensive with multiple devices 

  • Takes more time to set up – requires cables, ethernet cards or adapters and routers 

  • Ethernet cables can cause a cluttered look 

Due to the need for ethernet cables between all devices, this type of connectivity can cost both time and money. But this is often considered a reasonable trade-off for businesses that rely on the internet for their daily operations and to connect with customers, clients and partners. 

What Can a Company Do with High-Speed Internet and Ethernet Connections?

Think of all the internet-based applications that your company uses. Do you ever experience slowdowns due to poor or uneven internet service? Do these slowdowns ever create difficulties for your company, such as not having enough time to engage with your customers? There are many reasons why a business needs the fastest, most reliable internet available. 

  • Greater Productivity (email, chats, market research, customer service, SaaS applications) 

  • Improved Access to Cloud Applications (CRM software, content management systems, banking platforms, data analytics, remote backups) 

  • More Effective Team Collaboration (remote employees, online collaboration tools) 

  • Advanced Business Apps (VoIP calls, large data transfers, videoconferencing)  

  • In-house server hosting (eCommerce, company intranet, client portals) 

  • Enhanced Security and Agility (protection against hacking and cybercrime) 

To take advantage of all the internet has to offer, businesses must have the best connectivity available. 

How Does Our Connection Type Relate to Our Business Internet Plan?

In real-life applications, your connection quality and speed will ultimately depend on the speed of your provider’s internet plan. That is, even if you use a CAT 6 ethernet cable, which enables up to 1Gbps over a distance exceeding 300 feet, if your plan is 500 Mbps, that’s as much speed as you’ll get. The best ethernet cable and most expensive equipment cannot increase the speed of your internet plan. This is why, in addition to your ethernet connection setup, for optimal internet connectivity it is essential to have a robust plan from a forward-looking internet provider.
