Well all the networking issues with Ubuntu all seem to fall down to the same issue – IPV6 Its realience on this causes DNS and a whole lot of other issues with networking.

My tips for sorting out the networking?

1 Disable IPV6 in Firefox by typing about:config in the address bar and set network.dns.disableIPv6 to true.

2 Black list IPV6 in Ubuntu global by opening a terminal, typing sudo nano /etc/modprobe.d/blacklist
and adding blacklist ipv6 to the end of the file.

3 Don’t use the Gnome network monitor or nm_applet. Uninstall them and use Wifi Radar or WICD to select network.

4 Use Open DNS buy visiting www.opendns.com

5 Try seting up a DNS cache.
