How to Speed Up Internet: Firefox, Google Earth (No IpV6)

This works great for broadband connections, especially with older routers.

[b]Disable IpV6[/b]
The idea is basically that you disable IpV6 connections. At the moment most connections use IpV4 but this will change in the future so this “fix/ workaround” is fine at the present. We have IpV6 enabled as well as IpV4 but they conflict causing slowdown due to IpV6 trying to get a connection first.

[b]
Speedup Firefox only[/b]

In the [b]firefox[/b] address bar type: [b]about:config[/b], then change

network.dns disableIPv6: True

(just double-click)
[b]
Completely Disable IpV6[/b]

[b]1. Open your Gnome Terminal/ KDE Konsole and type[/b]
For Gnome

gksudo gedit /etc/modprobe.d/aliases

For Xfce

gksudo mousepad /etc/modprobe.d/aliases

[b]
2. Mousepad or Gedit will open and show you this file[/b]
(scroll down to see what to copy and paste)

[b]3. Now “Save” and “Reboot”[/b]

[b]Also:[/b]
There’s another way too: instead of changing the aliases file, create a file named bad_list in /etc/modprobe.d containing this line:

alias net-pf-10 off

This method will work even if /etc/modprobe.d/aliases gets replaced at some update.

I did this and had a noticeable increase in speed 😀
