If you are suffering from Slow internet while surfing net in Ubuntu than now you just dont need to worry about it because i’ve found one simple solution to this problem. I’ll provide two different solutions if one doesnot work then the other will definitely work.
1. First Step
root@desktop:~$ vi /etc/resolv.conf
#Generated by NetworkManager
#press Esc and wq! and then enter
2. Second Step
root@desktop:~$sudo gedit /etc/modprobe.d/aliases
