okay i've disabled ipv6 the method that I used was:
Edit /etc/default/grub file
Code:
gksudo gedit /etc/default/grub
Change
Code:
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”
to
Code:
GRUB_CMDLINE_LINUX_DEFAULT=”ipv6.disable=1 quiet splash”
Save and exit the file
Update the grub from the command line
And i got the same result when the ipv6 was on!
