When it comes to setting up your business network, a few questions always come up: Ethernet vs WiFi – which is better? Is Ethernet faster than WiFi? Is it more reliable? And most importantly, what’s the right setup for your business?
Both Ethernet and WiFi are essential for modern businesses, and each offers clear advantages depending on your environment, goals, and daily operations. In this guide, we’ll explore the difference between WiFi and Ethernet, compare WiFi types, and help you decide which is best for your network.
Ethernet refers to a wired networking standard that connects devices using physical cables – typically Cat5e, Cat6, or Cat6a – to a router, switch, or modem. Because it offers consistent performance and strong security, Ethernet remains the foundation of most business networks.
Some benefits of Ethernet include:
Many organizations rely on Ethernet for systems where dependable connectivity is essential, like retail point-of-sale systems, healthcare EMRs, or financial trading platforms.
WiFi allows devices to connect wirelessly to a network using radio signals transmitted from wireless access points (WAPs). It provides mobility, flexibility, and ease of access for users across a building or campus.
Benefits of WiFi include:
At TailWind, we install business-grade WiFi networks for distributed enterprises designed to minimize dead zones, reduce interference, and provide consistent performance across all locations.
Let’s tackle the most common question: Is Ethernet faster than WiFi? The short answer is yes, in most cases.
Ethernet connections are typically faster than WiFi, as they’re less affected by interference or signal loss. Here’s a quick breakdown:
WiFi 6 has narrowed the gap, but Ethernet remains the best option when speed is a top priority.
Ethernet connections don’t have a traditional “range.” A device is either plugged in or not, and the signal usually remains strong for up to 100 meters (about 328 feet) of cable length.
WiFi, however, depends on a few factors:
Obstructions like walls, floors, and electronic devices can weaken WiFi signals. For large spaces, businesses often combine Ethernet with multiple wireless access points to maintain full coverage.
Yes, Ethernet is more reliable than WiFi for critical applications. It provides a steady, uninterrupted connection that isn’t affected by interference or congestion, which enables it to deliver low latency and predictable speeds.
That’s why we often recommend Ethernet for credit card terminals, servers, and VoIP desk phones. However, WiFi has come a long way. With the right hardware and proper setup, business-grade WiFi can be reliable enough for most employees and guests.
WiFi 6 was officially released in 2019 and became widely adopted soon after. It introduced several important improvements, including:
If your business is still running on WiFi 5, it may be time to consider upgrading. A 2024 report found that 37% of businesses have already deployed WiFi 6E,1 which builds on the WiFi 6 standard and extends performance into the 6 GHz band. For most organizations, upgrading to WiFi 6 helps create a more stable, secure foundation that can support new technologies.
Understanding which WiFi generation your devices use can help you make better upgrade decisions.
Since WiFi 6 is backward compatible with WiFi 5 and earlier, upgrading your network doesn’t mean older devices become useless – but you’ll get better performance on newer hardware.
Ethernet and WiFi coexist in most networks. However, offloading high-bandwidth devices (like streaming boxes or VoIP phones) to Ethernet can improve WiFi performance for wireless users by reducing congestion.
At TailWind, we often recommend a hybrid network design that uses both Ethernet and WiFi. This setup strikes a balance between performance and flexibility, while reducing overall congestion.
If you’re still not sure which option is right for your needs, here are our recommended connectivity types for common use cases:
Typically, Ethernet is better for devices or applications that demand constant, high-speed connections. WiFi is more flexible and convenient, allowing employees and guests to stay connected anywhere in your workspace.
So, which is better: Ethernet or WiFi? The truth is, they’re complementary, not competitive. In most cases, WiFi is better for supporting mobility and guest access, while Ethernet is better for apps that need security, speed, and consistency.
At TailWind, we build networks tailored to your environment, user needs, and long-term goals. Whether you’re upgrading your infrastructure or connecting multiple locations, we’ll help design solutions that work with services like network engineering, wireless access point installation, structured cabling, and end-to-end IT infrastructure support.
