How Fast Can File Transfer Be on the Same Wi-Fi?
Discover the real-world throughput of local file transfers across Wi-Fi 5, Wi-Fi 6, and Gigabit routers. See benchmarks for 1 GB and 10 GB transfers.
Local file transfers on the same Wi-Fi network can achieve real-world speeds between 40 MB/s and 120 MB/s on modern routers. Because traffic stays inside your local network, transfer performance is determined by Wi-Fi standards rather than internet plan speeds.
Real-world Wi-Fi throughput by generation
| Wi-Fi Generation | Frequency Band | Real-World Speed | Time for 5 GB |
|---|---|---|---|
| Wi-Fi 4 (802.11n) | 2.4 GHz | 5–12 MB/s | 7–15 Minutes |
| Wi-Fi 5 (802.11ac) | 5 GHz | 45–75 MB/s | 1.2–1.8 Minutes |
| Wi-Fi 6 / 6E (802.11ax) | 5 GHz / 6 GHz | 80–120 MB/s | ~45–60 Seconds |
| Gigabit Ethernet | Cat 6 Cable | 110–125 MB/s | ~40 Seconds |
Frequently asked questions
Why does local Wi-Fi transfer slow down when other people stream Netflix?
Wireless routers share airtime across all connected clients. If other devices are downloading heavy streams, the router must interleave radio packets, slightly reducing maximum local transfer bursts.
