- WiFi 6 (802.11ax) will connect to 5 GHz frequencies. However, few routers can support WiFi 6 on 2.4GHz, but the standard is only ratified on 5 GHz radios for better efficiency.
- The 802.11ac operates only at 5 GHz frequency.
- If you have a dual-band router that supports 2.4 GHz and 5 GHz, it uses 802.11n (WiFi 4) on the 2.4 GHz frequency and 802.11ac (WiFi 5) on the 5 GHz frequency.
