How can i tell if someone else or another program is using my bandwidth?
Is there a software program?
I have a 2mb line and when downloading i get a good 180 kb/s,but it often drops down to 30 kb/s.
I close my download program and see that the router internet light is going crazy.
How do i figure out what else or who else is using the router?

Thanks guys
 
I use Kerio Control for maximum reporting on all devices and what they are doing on my network.

That may be overkill if not many devices and especially if you trying to isolate a once off rogue app.

For windows you can try this app: http://www.netlimiter.com. It will show all apps on the system using you internet connection. Found it to be very handy before I went Kerio Control.
 
If you suspect that somebody else is using your internet, most routers show which MAC addresses are connected to it, so if you see more than just your own, that might be it.

Otherwise you might have some spyware/adware/malware on your PC.

Log into the router and look at the DHCP leases issued. Each MAC address is a device.
If it's only you then it's something on your PC. You can use Resource Monitor in windows or any good Firewall program to see which process is downloading and where.

If you are downloading movies or series other people may be seeding from your downloads. They are uploading files that you have downloaded. Switch off your torrent downloads .
 
Also, the router light going crazy is not the most reliable indication of actual bandwidth flowing. I'd instead rely on my bandwidth stats by checking the ISP's website.

Changing your router's wifi password is a start. If it turns out your own computer is the culprit, and none of the obvious programs (like torrent or updates) are to blame, check out your startup entries by typing msconfig into the start menu search box > startup tab.

Then check for viruses, spyware, unneeded apps running, etc.
 
There's also a small prog called: who is on my wifi. You can see all devices connected to the wifi & disconnect / ban them.
