Disable IPV6 to speed up Internet.
Having IPv6 be the cause of ’slow’ connection is actually a common misconception, reinforced in that disabling some IPv6 features may help mitigate the problem, in most cases it is the result of bad network configuration. IPv6 itself does not in any way slow down connection, problems will arise however if the network is having a route out to the IPv6 internet but it is not operational, as the browser will try to connect and it will take a while to time-out, note this would also happen with a bad IPv4 internet connection.
To check IPv6 state open terminal and execute:
ip a | grep inet6
If this command shows some lines - IPv6 is enabled. If output is empty - IPv6 disabled. If its disabled , you are fine . if enabled follow the steps :
create fie named bad_list in /etc/modprobe.d containing the following line:
alias net-pf-10 off
Now reboot and you will find no IPv6 on your system!
This method will work even if /etc/modprobe.d/aliases get replaced at some update.
So happy browsing ……btw did I say that I use Ubuntu
