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.
What Is Ethernet?
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:
- Faster Speeds: Capable of up to 10 Gbps or higher with the right cabling.
- Low Latency: Ideal for real-time applications like VoIP and video conferencing.
- Stronger Security: Harder to intercept than wireless networks.
- Higher Stability: Not affected by signal interference or distance as long as cable lengths are within spec.
- Simplified Troubleshooting: Identifying and fixing issues is often easier with a wired infrastructure.
Many organizations rely on Ethernet for systems where dependable connectivity is essential, like retail point-of-sale systems, healthcare EMRs, or financial trading platforms.
What Is WiFi?
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:
- Improved Mobility: Users can roam freely without losing connection.
- Easier Management: No need to run cables to every device.
- Greater Scalability: Easy to connect new users and devices.
- Increased Flexibility: Perfect for mobile devices, guests, or hard-to-cable areas.
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.
WiFi vs Ethernet: Primary Differences
Let’s tackle the most common question: Is Ethernet faster than WiFi? The short answer is yes, in most cases.
How Much Faster Is Ethernet Than WiFi?
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.
Which Has a Longer Range?
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:
- WiFi 5 Range: Offers indoor coverage of around 100–150 feet.
- WiFi 6 Range: Slightly better due to improved beamforming and OFDMA.
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.
Is Ethernet Better Than WiFi for Reliability?
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.
When Did WiFi 6 Launch?
WiFi 6 was officially released in 2019 and became widely adopted soon after. It introduced several important improvements, including:
- Higher throughput for data-heavy workloads
- Better efficiency for multiple devices connected at once
- Improved energy management for IoT and smart devices
- Enhanced security with WPA3 encryption
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.
WiFi Types & Device Considerations
Understanding which WiFi generation your devices use can help you make better upgrade decisions.
- WiFi 5 (802.11ac): Common on devices manufactured from around 2014 through 2019.
- WiFi 6 (802.11ax): Standard on newer laptops, phones, and access points.
- WiFi 6E: Adds a 6GHz band for even lower interference but requires compatible devices.
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.
Does Ethernet Affect WiFi?
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.
When To Choose Ethernet vs WiFi
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.
Choose the Right Setup With TailWind
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.
