The fastest way to learn your true connection speed is to test wired — Wi-Fi adds overhead, latency and variability. Here's how they compare:
| Ethernet | Wi-Fi | |
|---|---|---|
| Max speed | Up to ~1–2.5 Gbps (cable) | Varies; often 30–70% of wired |
| Latency (ping) | Lowest, very stable | Higher, more variable |
| Jitter | Very low | Higher (interference) |
| Stability | Excellent | Affected by distance/walls |
| Convenience | Needs a cable | Wireless, flexible |
Which should you use?
- Wired Ethernet — gaming, video calls, large transfers, and your main work/desktop machine.
- Wi-Fi — phones, tablets, and casual browsing where convenience wins and the signal is strong.
Try it yourself: test wired vs Wi-Fi and compare. More tips in the improvement guide.
Frequently asked questions
Is Ethernet really faster than Wi-Fi?
For latency and stability, almost always yes. For raw download, a strong Wi-Fi 6 signal can rival wired, but Ethernet is more consistent and has lower ping and jitter.
Should I use Ethernet for gaming and calls?
Yes — wired gives lower, steadier ping and jitter, which matters more than bandwidth for gaming and video calls.
Why is my Wi-Fi so much slower than my plan?
Distance, walls, interference, the 2.4 GHz band, and older devices all cut Wi-Fi speed. Test wired next to the router to see your true line speed.
