Preferred Scanning Channels (PSCs) are a group of 20 MHz channels that are prioritized within the 6 GHz WiFi band, used by WiFi 6E and newer standards including WiFi 7. Instead of scanning the entire 6 GHz spectrum for an optimal channel, 6 GHz devices scan PSCs for efficient connectivity.
If you can connect on the 6 GHz band but can't access the Internet, or if your devices experience problems discovering your 6 GHz SSID, you might want to try using a different PSC. For more information about changing WiFi channels, see How do I change the wireless channel on my NETGEAR router?
