Many people have complained about the bootup time on laptops with Ubuntu 7.04 installed.  This is actually a problem with laptops dating back quite some time.  Windows addressed this issue with XP when the wireless card is disabled until the desktop loads to prevent it from conflicting with the regular NIC. Basically, the wireless card “waits” to find a network until it times out.  It will time out on any WEP, WPA or encrypted or authentication based wireless network.  Follow these instructions to eliminate this lag and speed up your boot time.

Edit the /etc/network/interfaces file by typing;

sudo vi /etc/network/interfaces

Now comment out the wireless card;

auto lo
iface 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

Save the file and exit. You will now have a much faster boot up time than before.
