My internet speed is 4 Mbps. In Windows, I get 2 Mbps download bandwidth, but in Ubuntu 12.04 LTS I only get a maximum of 20 Kbps. Why is it so?

Is there any background process which might be utilizing the internet connection? If yes, then how do I know that?

If you want the information in a Terminal you can run sudo lsof -i which will tell you all open internet connections (and listening processes too).

Your screenshot shows no anomaly, nothing unexpected (except maybe tomcat). So take one more step to investigate: you are going to look at actual bandwidth used in any connection with external hosts.

For this you need to

  • install iftop by typing sudo apt-get install iftop
  • run it with sudo iftop (or maybe sudo iftop -i wlan0 if the first command gives an error)

You will get a picture like

where the top line shows the overall used bandwidth (here very little bandwidth is used at the moment).

  • the problem is still persist sir, how do I overcome this? sometimes the download speed shows in Bps not even in 1 Kbps, or am I doing anything wrong with Ubuntu? – thirumalai raj Mar 17 '13 at 18:50

To find if there’s a process to utilize Internet, close your browser or any other applications you know, then Open System Monitor > Resourses [tab] and check for Recieving and Sent amounts. There should be 0 as you see below:
