 Thankfully, it is pretty straightforward to set up a functional Wi-Fi 6E network, as only the Access Point requires a regulatory update, while stations (clients) do not. This is because the regulatory framework restricts [[https://wireless.wiki.kernel.org/en/developers/regulatory/processing_rules#beacon_hints|the initiation of radiation (beacons)]], while clients are free to connect to any frequency the hardware is able to receive beacons on (even if it cannot initiate radiation on that frequency). Thankfully, it is pretty straightforward to set up a functional Wi-Fi 6E network, as only the Access Point requires a regulatory update, while stations (clients) do not.
