Comment 5 for bug 94993

After one of the latest udates, I had the same problem and found out that during the boot process my PC hangs at "networking".
My workaround was excluding some commands of /etc/network/interfaces.

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 dhc

auto wlan0

I am NOT a computer expert but just a user.
I found that this change didn't effect my network connections, both wired and wireless.
