I need to know which computer is consuming my bandwidth. Is there a tool to do this?

    What operating systems are you using on your network - Windows, OS X, Linux, or a mixture? Oct 12, 2009 at 22:38

    I took a peek at his other questions / answers on the site. Seems like windows to me.

  • @thecie007: You're right in a way. But the problem is, I don't use any. I'm going to choose one and I know only the two I mentioned in my question.

If you want to graphically display your local network connections, you may be interested in etherape. Free and cross platform. The thickness of the connection is an indicator of traffic volume.

    interesting name for software.

  • ok this is interesting, but, how can I compile it for Windows...

  • Sorry, I ddin't see the windows reference. If it was me, I probably wouldn't bother - because I'm lazy. It has too many dependencies (Gnome, etc). I would install it inside a virtual machine running a nice simple linux distro. For example, use VirtualBox on your Windows host and Ubuntu as the guest OS. That's a lot for 1 application, but still easier than compiling etherape IMHO. Oct 14, 2009 at 0:30

    @John T: EtherApe is one of those unfortunate names like expertsExchange or penIsland

At the router level would be the easiest as it wouldn't involve installing software on each machine separately. Tomato Firmware is great and automatically monitors bandwidth in the logs section, you can use it along with IPTables (Linux) for a complete traffic monitoring solution. Since you are probably on Windows, you can use it in a VM as well.

For a software solution for each computer, take a look at the freeware tool NetLimiter, the bandwidth monitor is free:

  • I'll try installing the tomato firmware then reply.. thanks!!!

    Make sure it is compatible with your router before installing! You will also need IPTables to see per-computer statistics. good luck :)

The Windows Resource Monitor on 7 (and Vista?) has grown quite advanced in what it shows under "network".

    @Kamyar It can be SLIGHTLY hidden in a way...great thing built in though! Oct 21, 2011 at 0:03
  • I guess the OP means which software use my bandwidth and not which computer is consuming my bandwidth

I could not find a lot of free ones to monitor all the entire network with one application, except maybe Spiceworks:


There are plenty that can monitor each computer you install it on. A couple are:



If you want to find others, Google "monitor bandwidth usage on network" (without the quotes)

Now as far as limiting them, I did not find any software, because most of the time, that is handled by the router. After all, it is easier to do there since all traffic has to go through it, otherwise, you would need an application on each PC to limit bandwidth usage.

I am sorry to say that I looked through your manual, and your router has no features to limit bandwidth or quality of service.


TCPView allows you to see the connections. Process Monitor can help you filter on actual data transfer.

Wireshark goes to the level showing you the packets in detail. Fiddler2 is in specific for HTTP transfer.


You can use DU Meter + dumeter.net to monitor Internet bandwidth usage on your network:

dumeter.net displays bandwidth usage of all your computers connected to your account. Your Internet provider can show only the overall totals, which are of course useless if you have several computers in your house and would like to know how much bandwidth each of them used.

DU Meter is not free, however dumeter.net is currently free for all DU Meter 6.x users.

    Unfortunately this requires an installation on each PC and may not account for mobiles and tablets etc.

If you have a cisco router, you can use scrutinizer. You need to modify a few lines of code in your router to enable netflow, but I've found this program to be fantastic, and it's free.


You can use WhatPulse:

  • Free
  • Linux/Win/Mac
  • It records the network use
  • Stats are available online as well as on the desktop client.
  • Support several computers

On each computer:

I have finally finished implementing the Network Utilization Monitor tool which helps me to monitor internet bandwidth utilization by each computer in my home network (including phones/tablets). I have shared internet with my neighborhoods and sometimes when the internet hangs I want to know what is the reason. What does consume 8 MBit/sec input and 0.5Mbit/sec output directions.

In the EtherApe I did not find how to how separately calculate incoming and outgoing traffic.

This tool requires L2 Managed Switch with option to mirror all traffic to specified Port.

  • I'm going to test application on Network Hub (repeater). If it works, then you do not need L2 switch. And it will be more cheaper solution. Oct 28, 2015 at 17:05
  • Did not find cheap repeater. Looks like there is no sense to buy it. Unless you have it already. Apr 16, 2016 at 22:05

Glasswire is an amazing tool. Free and paid versions are available.

This image illustrates...

I have been using Plex and Twitch a lot this evening. Install it. Leave it running. Check back after a few hours or days to see what is going on for that PC.


You can follow the below simple steps to track your internet usage on the network.

  1. Press the Windows key + I keyboard shortcut to open the Settings app.
  2. Click Network & internet.
  3. Click Data usage.
  4. Open the Usage details link to view network data usage for all your applications installed on your computer.
