Wi-Fi 5 (ac) vs Wi-Fi 6/6E (ax)

Side-by-side comparison, when-to-use-each guide, and instant conversion. Reviewed for 2026.

Quick answer: Wi-Fi 5 (802.11ac, 2014): up to ~3.5 Gbps theoretical, 5GHz only. Wi-Fi 6 (802.11ax, 2019): up to ~9.6 Gbps, much better in crowded networks (OFDMA). Wi-Fi 6E (2021): adds 6GHz band (less crowded, faster). Wi-Fi 7 (802.11be, 2024): up to ~46 Gbps and 320 MHz channels.

Frequently asked

?

Will Wi-Fi 6E reach further than Wi-Fi 6?

No — the 6 GHz band has shorter range (higher frequency = more absorbed by walls). 6E excels at speed in close range; 2.4 GHz still beats it for reaching the far corner of a flat.

?

Do I need Wi-Fi 6 if my internet is only 100 Mbps?

For pure speed, no. For multiple devices on the same connection (smart home, kids streaming, video calls), Wi-Fi 6's improved handling matters more than top speed. Worth it if you have 15+ Wi-Fi devices.
