Disable IPv6
From MEPIS Documentation Wiki
[edit]
Disabling Solely In Firefox
The way Firefox configures its use of the internet protocol IPv6 can slow down your connection. To disable IPv6 in Firefox:
- In Firefox in address bar type: about:config
- In Filter field enter: ipv6
- change the value for network.dns.disableIPv6 to true
---
Since other applications such as Opera or Thunderbird can also experience this slowdown, you may want to turn off IPv6 system-wide. To do this, open a console and as root enter:
echo "alias net-pf-10 off" >> /etc/modprobe.conf
This change takes effect after a reboot.
Thanks to Stefan_Nicolau for this tip.

Disabling System Wide
- Open a Filer Manager Session - Super User Mode
(KDE-Start> System> File System> File Manager Super User Mode)
- Navigate to directory /etc/modprobe.d
- Right click in empty space in the browser window and choose Create New > Text File ....
- Name the new file 00local (that's zero zero .... and no 3 letter .extension at end)
- Open the file by clicking on it (still in SuperUser Filemanager) and paste these two lines:
alias net-pf-10 off alias ipv6 off
- Save and close the file
- Still in SuperUser Filemanager, click to edit the file named blacklist.
- Add this line to the very bottom of the file:
blacklist ipv6
- Save, close, and at next reboot IPv6 should be off system wide, and hopefully browsing will be a little quicker.
