rfkill: Unblock devices by type (e.g. bluetooth, wlan).
$ rfkill unblock ${wlan}
try on your machine
The command "rfkill unblock ${wlan}" is used to unblock a wireless interface (usually referred to as "wlan" in this case) that has been blocked using the rfkill facility in Linux.
Here's a breakdown of the command:
- "rfkill" is a utility in Linux used to manage wireless devices' soft and hard blocks.
- "unblock" is an option used with "rfkill" to remove the software-based block on a wireless device.
- "${wlan}" is a placeholder variable that represents the specific name or identifier of the wireless interface (e.g., wlan0, wlan1, etc.) to be unblocked.
By executing this command, RF (Radio Frequency) blocking on the designated wireless interface is removed, allowing it to establish connections and interact with wireless networks again.
