WiFi 6 5GHz

If your adapter supports 802.11ac , it will definitely support 5GHz. In most cases, 802.11n adapters will also support 5GHz. You can also right-click on the adapter in Device Manager, click Properties and then switch to the Advanced tab. You’ll see a list of properties, one of which should mention 5GHz.

Currently, devices are already on the market with WiFi 6 compatibility; these devices support the new standard, but they work on the same 2.4 GHz and 5 GHz spectrum .

But all Wi-Fi 6 routers will include a 2.4 GHz band that works with all existing clients on the market.
