How long does a 200 GB file transfer take over WiFi 7? MLO and speed guide

A 200 GB transfer over WiFi 7 works out to 5 minutes 20 seconds at a realistic 5 Gbps sustained rate. 802.11be's advertised peak is 46 Gbps across the combined 2.4 / 5 / 6 GHz bands. Achievable only in lab conditions. Real devices deliver 3-6 Gbps on a single high-bandwidth client.

How this is calculated

WiFi 7's big practical win is Multi-Link Operation (MLO), which lets a client use two bands simultaneously, sustaining throughput even if one channel degrades. In a busy apartment building with dozens of overlapping 5 GHz networks, WiFi 7 feels noticeably steadier than WiFi 6. The peaks are similar but the floor is much higher. Wired 10 GbE still wins for raw speed, but WiFi 7 is finally approaching wired Gigabit as a usable network fabric for bulk transfers.

Verdict

5m 20s for 200 GB over WiFi 7 is genuinely close to a 10 GbE wired run. For the first time, wireless is fast enough that "just transfer it wirelessly" is a reasonable answer for large files.
