I was trying to fix my wifi on Kali Linux the other day and was following some tutorial. That didn't work, so I read somewhere that if I run this command

iw dev wlan0 del

After that command I can't seem to find my wlan device. When I type iwconfig it shows this:

lo        no wireless extensions.

eth0      no wireless extensions.

Anyone know what should I do now?

To undo deletion of wlan0, you can recreate it like so:

iw phy phy0 interface add wlan0 type managed

This is much faster than rebooting and more reliable than restarting network-manager.

Easiest way is to just reboot. The type of configuration change you've made does not persist across reboots.

    do sudo service network-manager restart. It will reinitalise all the network interfaces...

  • that might work, if you have network-manager installed, and if network-manager knows how to recreate the necessary device. That's not a given. Aug 23 '15 at 21:42
