wlan.channel_mask

This command specifies the wireless channel masks for enabling and disabling various channels. This controls which b/g radio channels can be used by the radio for network connections.
The value for this command is a bit field where a 0 disables a channel and a 1 enables the channel. Starting from the right, bit 0 is for channel 1, bit 1 for channel 2, etc. This can be used to limit the channels scanned for networks, which may slightly improve connection and roaming speed. It also used to ensure compliance with the regulatory domains of your location.
