Problems with Bandiwdth Usage

Hello,
i have WIN XP PRO, Cable Connection (Motorola SB5100E attached via ethernet cable, connected directly to my computer), Kaspersky Anti-virus, Kaspersky Anti-Hacker, AD-Aware, Spybot S&D & Spyware Blaster. I don't have any current virus or spam on my computer. I use Bandwidth Meter program to measure my bandwidth usage. The "problem" here is that Bandwith Meter is constantly showing usage of my bandwidth, even if i'm not downloading the whole day it will show that i downloaded about 1 gigabyte. I suspect that it might be a Modem Hardware problem but i may be wrong. I also contacted my ISP and they said i downloaded 30 gigabytes last month but i actually didn't. Although i'm using "FLAT" Connection i want to know is this normal modem behaviour or is it faulty?

Thank you in advance.

    What I would do is unplug your cable modem from your computer and contact your ISP and notify them that you disconnected it. Leave it unplugged for a bit and then call them back later and see how much bandwidth you have used since you unplugged it. If the cable modem is faulty that should show your ISP that it is.

    Are you running any sort of bit torrent programs in the background that would be constantly going in the background?

    Do you own this cable modem or was given by ISP? I know my cable modem was given by my ISP and it was used. Who knows what is wrong with it.

    Does your bandwidth checker see what ports are being used for this bandwidth?

    Hello,

    thank you for the answer. I will call my ISP tomorrow and do what you suggested. All i found out in the past when i contacted my ISP is that bandwidth usage for a certain day on their machines matched/ or showed exactly what my Bandwidth program logs.

    Concerning the background programs. Every time i'm really downloading something (opening websites or downloading from ftp/http) those monitors in the system trays are either blinking or are on. So no, there are no programs in the background that i know. Automatic Updates in XP are Off.

    Yes, i own the modem, the cable-guy brought it in the box unpacked, and the modem is still under a warranty. I don't think that would be a problem to change it but i just to be sure if it's really a modem glitch or something else.

    No, as far as i know there is no option to monitor ports in this program. I will check and find some other program that can monitor ports and bandwidth usage. I will let you know.

    If you really want to know what is passing along your connection, you can use a utility like Ethereal to analyze the packets that are streaming by your network adapters..  Not that difficult to use, once you understand the concepts of the program...

    FE, thanx for a tip,

    i started a Capture and all i found out is almost 98% of the traffic is ARP requests. Most of them are from my subnet so i assume everything is OK. This is kinda annoying as i can't really track my bandwidth. If you have a suggestion what to do in this case, that would be helpful.

    I see that you are not using a router in your network.  ARP requests do not pass through routers, so this is one way to stop these from getting out to the WAN...  Just a thought..  :)

    Personally, I HIGHLY recommend that all my clients install a router, whether they are networking a LAN or not.  A NAT enabled device (router) will 'hide' your private LAN from the outside, and greatly increases security on your systems...  For < $50, it is well worth the price...
