 ====== OpenWrt Custom wireless-regdb ======
+Note: Do not use the patch below if you are in Singapore, as wireless-regdb is now maintained once again and updated Singapore regulatory rules have been released.
+This information is just provided for reference in case one needs to test changes to wireless-regdb on an OpenWrt wireless AP.

 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).
