- copy all of the above content
#create new file using vi in terminal vi interfaces_wlan0 #hit i for insert and then right click to paste #ESC:x to save # overwrite the old interfaces file with eth0 configuration # create a backup if need to before overwrite sudo cp interfaces_wlan0 /etc/network/interfaces #turn off eth0 before restarting with new wifi configeration sudo ip link set eth0 down #restart networking sudo /etc/init.d/networking restart #check wifi status iwconfig #test ping www.google.com #if doesn't work need to reboot #security option sudo chmod o=-r /etc/network/interfaces
