Tracking/Network Tools

Hello

Simple question on how to determine if massive network loss is due to
traffic on the LAN or if someone could be piggy backn the connection /sharing
bandwidth somehow?

Arris modem
The connection is Cable. The ISP head end have upgraded to Fiber Optics
recently.

Early morning to around 5pm my connection when doing a speed test on the LAN
gets around 1200 KB/s for the speed test. A round the same time every evening
the connection drops to around 300 KB/s. Still a decent speed.

My ISP says it could be due to heavy traffic. Possible. Their reason due to
traffic on the LAN seems hog wash. A drop of 900 KB/s is a 75% loss in
network capabilty. A 900 KB/s loss just seems unacceptable for any ISP.A tiny
bit of slow down is expected but a whomping loss like that is suspicous.

If that were the case perhaps they should not be in Business as an ISP or
hire techs who know how to design and implement a proper network. Specially
when folks pay for a 10Mbps connection technically it should remain that way
all the time. The last cable ISP I was with catered to a city of more then
800 000 people and had a constant 5 Mbps connection all the time.

My question is what methods & network tools can I use to track & find what
or who is causing the slow down ?

Thanks for any & all help

Hi
The way you track depends on the exact topology of the Network and the
Internet connection.
Since you did not provide the information it can not be answered.
However if it a small private LAN, connect only one computer to the Modem
document the Bandwidth and send it to the ISP.
There are applications that would track traffic on a single computer.

Hi Jack

Thanks for the speedy reply and for the link. The program looks to be a
useful network utility.

The network topology would could be in depth explanation. Where the techs
that run the ISP could give an exact topoology for the network. A cable ISP
supported by an Arris modem which they have access through the LAN by
connecting to it for troubleshooting. For nodes and other network topology I
wouldnt know what exact technology thats implemented.

If you do have further suggestions and links to more network tools that can
scan and pinpoint LAN congestion or othe trouble spots with in a LAN I would
appreciate it.

Cheers

Hi
If you have few computers running at home connecting to the Internet via a
Router, it is called peer-to-peer topology and it does not lend itself to
one central monitoring. In such case you have to install the software (like
the one that I linked to before) on each computer and collect the data every
day until you find the trouble.
Otherwise if you have a local server computer that controls the LAN traffic,
the server should have the ability to provide the traffic information.
