Speed up Ubuntu boot up w/ mobile laptop
When I would take my laptop to class or somewhere there would be a long delay, about a minute, for it to realize that it was not going to get an IP address from the ethernet jack because no cable was plugged in… So after some googling I found a slight work around… You need to edit your /etc/network/interfaces file… You need to comment out a few lines such as mapping hotplug, script grep, map eth0, and auto wlan0.. below is my interfaces file… In bold are the lines I commented out…
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# This is a list of hotpluggable network interfaces.
# They will be activated automatically by the hotplug subsystem.
#mapping hotplug
# script grep
# map eth0
# The primary network interface
iface eth0 inet dhcp
#Wireless network card stuff...
iface wlan0 inet dhcp
wireless-essid (wireless SSID here)
wireless-key (Put your WEP Key here)
#auto wlan0
By commenting those lines out, there is no longer a networking delay when booting up… You do however have to enable which device what to use when you do boot up which is no big deal…
