Ethernet Offers Faster Top Speeds
The most notable difference between the two is speed. Ethernet connections can hit faster maximum speeds, for a few technical reasons:
-
Higher raw bandwidth – The latest Ethernet cables like Cat 6 and Cat 6a offer up to 10 Gigabits per second (Gbps) throughput. Even affordable Cat 5e cables still provide 1 Gbps. Compare that to Wi-Fi 6, which tops out at 2.4 Gbps.
-
Less interference – Ethernet cables give you a direct line from your computer or device to the router. Wi-Fi signals travel through the air, exposing them to interference from appliances, walls, and distance. This can slow things down.
-
Lower latency – Latency refers to the time it takes data to go from point A to point B. Wired networks have lower latency because signals can travel faster through cables than over the air. This really improves responsiveness for gaming.
Numerous real-world speed tests show Ethernet consistently outperforms Wi-Fi, often by a wide margin. For example, using Ethernet I measured download speeds over 700 Mbps in my office. But connecting to Wi-Fi in the same location, speeds dropped to around 300 Mbps.
However, Wi-Fi has improved enormously. With a strong signal, Wi-Fi 6 can deliver speeds fast enough for most daily tasks like web browsing, streaming HD video, or joining Zoom meetings.
But for data-heavy uses like 4K streaming, online gaming, video editing, or transferring huge files, Ethernet remains the best option when available. It offers the bandwidth and stability to handle these demanding tasks smoothly.
Other Notable Differences
Beyond straight speed, there are some other key ways Ethernet and Wi-Fi connections differ:
Convenience
Wi-Fi offers unmatched convenience and flexibility. You can connect wirelessly anywhere in your home without dealing with cables. This makes getting online easy with laptops, tablets, phones, and anything portable.
With Ethernet, cables tether you to the location of your router or modem. This limits mobility. Cables can also create clutter. However, powerline Ethernet adapters let you extend your wired network to other rooms using existing electrical wiring.
Number of Devices
You can connect many devices to the same Wi-Fi network simultaneously. Most consumer routers support at least 50 devices these days.
Ethernet is limited by the number of ports on your router, usually 4-8. You can add more wired connections using an Ethernet switch. But each gadget needs its own dedicated cable back to the switch or router.
Security
Ethernet has a natural security advantage over Wi-Fi. It‘s not a wireless signal that can be intercepted from a distance. To infiltrate a wired network, you‘d need physical access to the cables and ports themselves.
Wi-Fi signals travel over the air, making them more susceptible to hacking. Always use modern encryption like WPA2 or WPA3 on your wireless network to keep it secure. Virtual Private Networks (VPNs) also add a layer of security and privacy.
Availability
Almost every modern computer or mobile device includes built-in Wi-Fi capability – phones, tablets, laptops, smart home gadgets, TVs, game consoles, you name it.
Meanwhile, Ethernet ports are no longer as common. Many slim laptops and tablets have ditched them entirely. For anything without a port, you‘ll need an adapter or dongle.
As you can see, both Ethernet and Wi-Fi have pros and cons. Keep these differences in mind when deciding how to connect.
When to Choose Ethernet
For certain use cases, Ethernet remains the preferred connection method:
Gaming PCs – For competitive online gaming, low latency is critical. Wired networks offer much lower ping times than Wi-Fi, giving you faster reactions and less lag. Serious gamers should always use Ethernet for gaming rigs if possible.
Home theater PCs – Streaming 4K or 8K video requires massive, steady bandwidth. Even the newest Wi-Fi can‘t match the speeds and reliability of Ethernet. So for the best streaming experience, connect your home theater PC directly to your router.
Desktop workstations – For time-sensitive creative work like 3D rendering or video editing, a wired connection avoids any network congestion or glitching that could interrupt your flow.
Network devices – Servers, network-attached storage (NAS) devices, printers and other central network equipment should use Ethernet for full-speed wired access to them.
Internet of Things (IoT) gadgets – Many smart home devices like security cams now include Ethernet ports. Use wired connections to ensure reliable connectivity without eating up your Wi-Fi bandwidth.
Businesses – Ethernet remains the standard for wired office networks. Cat 5e or Cat 6 runs to cubicles, desks, and conference rooms to offer the fastest, most dependable performance, supplemented by Wi-Fi.
Bottom line – if you have a stationary desktop computer, entertainment device, or business equipment requiring maximum speed and minimal lag, use Ethernet.
When Wi-Fi Excels
Thanks to convenience and mobility, Wi-Fi now handles the majority of wireless connections:
Laptops – Portable work and personal laptops depend on Wi-Fi in coffee shops, hotels, offices, and homes. An Ethernet cable would limit your ability to move around.
Phones and tablets – Without Ethernet capability, today‘s mobile iOS and Android devices are designed for Wi-Fi access. Wireless allows you to be productive or entertained anywhere.
Smart home gadgets – Thermostats, lights, sensors and appliances enable home automation via Wi-Fi. Running cables to them would ruin the flexibility.
Media streamers – Devices like Roku, Fire TV, Apple TV and Chromecast all connect wirelessly to deliver content to your TV. While you can use Ethernet, Wi-Fi works well.
Gaming consoles – The newest PlayStation, Xbox and Nintendo Switch all support Ethernet for lag-free online play. But their wireless works fine for most gaming and streaming.
Workshops and garages – Add Wi-Fi coverage to backyard sheds and garages with access points or mesh nodes. No need to dig trenches and run lengthy cables across your property!
Public hotspots – When away from home, we rely on Wi-Fi hotspots in hotels, airports, libraries, cafes and stores to get online. Ethernet cables would be inconvenient.
Multiple devices – Households often need to connect phones, TVs, PCs, tablets, and more. Wi-Fi allows everyone flexible access, while Ethernet would require cabling each device.
If a device moves around or needs untethered access, Wi-Fi is really the only option. For non-essential networking of phones, tablets, smart home tech, and media gadgets, wireless works great.
Boost Your Wi-Fi Speeds
While wired networks outperform wireless, you can still optimize your Wi-Fi for faster speeds:
-
Upgrade to Wi-Fi 6 – Invest in a Wi-Fi 6 router and devices with Wi-Fi 6 support. This latest standard offers expanded bandwidth, speed, and coverage vs. Wi-Fi 5.
-
Reduce interference – Position your router centrally in a location away from electronics that may cause wireless interference like baby monitors, microwaves and cordless phones.
-
Use 5GHz band – Dual-band routers offer 5GHz and 2.4GHz channels. Connect devices to the less crowded 5GHz band for better performance.
-
Change channels – If speeds are slow, try switching your router to a clearer channel to avoid interference from neighboring networks.
-
Limit connected devices – The more devices sharing Wi-Fi, the more congested the network. Use Ethernet for gadgets whenever possible, and disable Wi-Fi on stuff when not in use.
-
Stay central and closer to the router – Place stationary gadgets like smart TVs and game consoles closer to the router in a central location to ensure the strongest signal.
-
Upgrade old routers – Router hardware can deteriorate over 3-5 years. Newer models maintain stronger wireless coverage across your home.
While no Wi-Fi network will match Ethernet speeds, these tips can still help maximize your wireless performance.
