Bandwidth Measurement

Hi, Is there a way I can findout how much bandwidth we are getting from our isp.Is there software that I can use.We have a 256kb line but at times when there is no one in the building,using www.speakeasy.net/speedtest/ i get 16kbps download speed.Is there a way I can see who is slowing down the internet that's if its not the isp's problem.

hi,
the best way to test your bandwidth is to use something which your ISP prescribes to check your bandwidth. any other website would be testing data transfer rates between your computers and their servers. hence you will not get the entire picture.
if your agreed bandwidth is 256 kbps, and your are only getting 16 kbps, there is a huge short fall.
i would suggest your check your CPE device or devices and all other network nodes. the best way to do this is to study the packets travelling between machines.
try ethereal
www.ethereal.com/
it will help you study the packets flying about in your network. you might be able to pin point to the rougue device in your network, or even challenge your ISP for low quality of service.
