Automatic Channel Selection
(auto | auto-no-dfs)
Have the router automatically select the best channel to use from among all channels or from among all channels except for those with dynamic frequency selection (DFS) capabilities.
Airport radar uses frequencies that overlap DFS channels. If you are using a 5-GHz radio band, and if your installation is near an airport, it is recommended that you configure auto-no-dfs, to remove DFS channels from the list of available channels.
Default: auto
