Some may find that out-of-the-box, Hardy Heron’s network performance is painfully slow. By default, IPv6 is enabled, and chances are good that your nearest router can’t speak the language nor interpret DNS requests efficiently.
To disable IPv6, open a shell and append the following to /etc/modprobe.d/blacklist:
# disable ipv6
blacklist ipv6
blacklist ipv6
Reboot.
To verify that IPv6 is disabled, run
lsmod | grep ipv6
or
ip a | grep inet6
The commands shouldn’t return any information. Open Firefox and let ‘er rip!

A lot easier than I thought it would be, thanks!

Which blacklist file, I have the following:
blacklist-aht_pci.conf
blacklist.conf
blacklist-firewire.conf
blacklist-framebuffer.conf
blacklist-oss.conf
blacklist-watchdog.conf
Thanks,
Mike
i couldnt edit blacklist file, and cant run nautilus, any way to change permission on the file?
Mike S,
In newer versions of Ubuntu, the file you need to modify is blacklist.conf.
Dogafin,
Give this a shot:
sudo gedit /etc/modprobe.d/blacklist
Enter your super user password and you should see the file open. If you don’t know the password, type:
sudo passwd root
Enter the new password twice, then try to open the blacklist file.
