Description
Shows whether or not APs using this radio profile will advertise intolerance of 40 MHz
operation. By default, 40 MHz operation is allowed.
If this parameter is enabled, the radio will stop using the 40 MHz channels if the 40 MHz
intolerance indication is received from another AP or station.
When this feature is enabled, all legacy transmissions will be sent using a single
antenna. This enables interoperability for legacy or high-throughput stations that cannot
decode 802.11n cyclic shift diversity (CSD) data.
This feature is disabled by default and should be kept disabled unless necessary.
