Laptop recovery

I finally managed to recover the laptop that was freezing when loading gnome. I found many links talking about this similar problem, and I'm not really sure why it happened in the first place.
Whatever the cause, I'm glad that I found a solution that has Ubuntu up and running again on the laptop.
I'll post the links here along with the solution that worked for me.
Fix 1:
/etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
auto ath0
iface ath0 inet dhcp

then restart networking with: sudo /etc/init.d/networking restart

Fix 2
Blacklist ipv6

Fix 2 is what finally got things running for me again.
gksudo gedit /etc/modprobe.d/blacklist
add a line that reads:
blacklist ipv6
reboot

Another Ubuntu problem solved in Ubucrates Classroom.
Class dismissed.
