Q:

Kali linux 2.0 wlan0

I executed the following command not knowing that it would disable the wireless option from my settings.
iw wlan0 del

Is there any way to reverse the command?
Any help would be really appreciated. Thanks in advance.

A:

You may be able to find helpful information here on reconfiguring your wireless interface. 

https://wireless.wiki.kernel.org/en/users/documentation/iw

Use iw phy phy0 interface add wlan0 type managed to add the interface back. If the device is called something other than phy0, then substitute it in.

https://help.ubuntu.com/community/WifiDocs/WiFiHowTo

Be aware that this is an Ubuntu support article, but it is also Debian based so it may provide help for managing wireless interfaces in Kali Linux.

Best of luck.
