I would like to make a Virtual Router on Ubuntu 12.04
but i am getting this error message when i run the last terminal command
Configuration file: hostapd.conf
nl80211: Could not configure driver mode
nl80211 driver initialization failed.
hostapd_free_hapd_data: Interface wlan0 wasn't started
solution:
sudo nmcli nm wifi off
sudo rfkill unblock wlan
sudo ifconfig wlan0 10.15.0.1/24 up
sleep 1
sudo service isc-dhcp-server restart
sudo service hostapd restart
