If you are experiencing long boot times, try this fix: Comment out all lines in /etc/network/interfaces by puttig a "#" in front of everything except loopback interface: sudo gedit /etc/network/interfaces comment out every line (put a # at the beginning of the line) except for this one: auto loiface lo inet loopback This is what mine looks like: auto loiface lo inet loopback #auto eth0 #iface eth0 inet dhcp #auto eth1 #iface eth1 inet dhcp #auto eth2 #iface eth2 inet dhcp #auto ath0 #iface ath0 inet dhcp #auto wlan0 #iface wlan0 inet dhcp
