WiFi vs Ethernet: Compare Your Wired and Wireless Performance
WiFi is convenient but almost always slower and less reliable than a wired Ethernet connection. Our comparison tool helps you measure exactly how much performance you are giving up by using WiFi, across speed, latency, jitter, and packet loss, so you can make an informed decision.
Launch in Mission ControlWhat It Measures
This tool runs identical tests on your current connection and lets you compare results from WiFi and Ethernet sessions side by side. Key metrics include download speed, upload speed, latency, jitter, and packet loss to show the full performance difference.
How It Works
- Runs a complete baseline test on your current connection
- Prompts you to switch connections and run the comparison test
- Displays side-by-side results comparing all key metrics between both sessions
- Calculates percentage improvements from switching to Ethernet
Why It Matters
WiFi performance is highly variable and depends on distance from the router, interference, and the number of connected devices. For gaming, video conferencing, and large file transfers, Ethernet delivers lower latency, more consistent speeds, and zero packet loss from WiFi interference.
Understanding Your Results
A wired Ethernet connection should achieve near-theoretical plan speeds with latency under 5ms to your router. WiFi performance varies widely: 5GHz WiFi close to the router can approach wired speeds, but latency is always higher and WiFi jitter is typically 2 to 5x higher than Ethernet.

How much faster is Ethernet than WiFi?
Speed differences range from minimal (if you have fast 5GHz WiFi close to the router) to dramatic (if you are on 2.4GHz WiFi far from the router). More important than speed, Ethernet typically reduces latency by 1 to 4ms and virtually eliminates the jitter and packet loss that WiFi introduces.
Is WiFi 6 as good as Ethernet?
WiFi 6 significantly closes the gap, especially in the 6GHz band (WiFi 6E). Modern WiFi 6E can deliver multi-gigabit speeds with latency approaching Ethernet on compatible hardware. However, Ethernet still maintains an edge in latency consistency, packet loss, and reliability in congested RF environments.
When is switching to Ethernet most beneficial?
Ethernet provides the greatest benefit for gaming (latency and jitter are critical), video conferencing from a fixed workstation, large file transfers and backups, smart TV streaming with WiFi dropouts, and any application that requires consistent rather than variable bandwidth.
What if I cannot run an Ethernet cable?
Powerline adapters use your home's electrical wiring to transmit network data and usually outperform WiFi in latency and consistency. MoCA adapters use coaxial cable wiring for even better performance. WiFi mesh systems with a wired backhaul also improve wireless performance significantly over standalone routers.
