How long does it take to copy 100 GB over WiFi 6? OFDMA and signal guide
A 100 GB transfer over WiFi 6 works out to about 11 minutes 7 seconds at a realistic 1.2 Gbps sustained rate on a clean 5 GHz 160 MHz channel. 802.11ax's marketing peak is 9.6 Gbps across four antennas, but 1-1.5 Gbps sustained is the mainstream per-device reality for a modern laptop at close range.

How this is calculated
WiFi 6 mostly matters for multi-device consistency rather than single-link peak. OFDMA and MU-MIMO keep speeds stable when the network is busy, which is where WiFi 5 falls apart. For a single device doing a bulk transfer, the practical improvement over 5 GHz 80 MHz WiFi 5 is 2-3x, not the 7x the marketing implies. WiFi 6E on the 6 GHz band typically does better than 5 GHz because the spectrum is cleaner.
Verdict
11m 7s for 100 GB over WiFi 6 at good signal is a useful benchmark. Most laptops and phones land in the 10-15 minute range depending on distance and congestion.
