I have windows XP home sp2, connected to a linksys voip router (rtp31p2), connected to a comcast cable modem. There are 2 other computers on thisnetwork. There is no wireless.
My internet is slow, and something I believe may be uploading or downloading stuff.
I turned off my torrent programs, no help.
Hijackthis says everything is kosher. (programs running & installed)
Zonealarm firewall says is blocking anywhere from 3 to 20 intrusion attempts every second.
I installed "NET Traffic Meter 1.4" but I don't know how to use it to find a problem.
I'm running spybot & adaware just to be safe.
On MY computer, pinging 4.2.2.2 gives me an avergage of 23 ms.
Numion.com says upload and download speeds are about 1,000 kilobits/sec.
On a different computer on the same network, pinging 4.2.2.2 gives me an average speed of 21ms
Numion.com says upload is 1,000+ kilobits/sec, download is 4,000+ kilobits/sec
______
(1) Is there a way to assess which INDIVIDUAL process (or other thing?) is using up the internet or network resurces, much the same way task manager can show you which process is using RAM or CPU or Virtual Memory resources?
(2) Is there a program that monitors this stuff OVER TIME, for one or more computers? So I can see a graph of what the upload / download activity was for a given PC, for the last 24 hours (for example?)
(3) what is the normal amount of data kB/s to be uploading or downloading on a Windows XP computer, assuming the user is NOT downloading anything that he's aware of?
(4) Is there a better way to go about this? (e.g. use the ROUTER maybe?)
Thanks EE people!

Regarding the VOIP router... I don't see an online manual after a quick search... My question would be (please consult your print or CD based manual)... are the SWITCHED ports routed (part of the NAT).
If so... no, the device you have is a router
if NOT... yes, get a router and configure:
MODEM ---> Router -----> VOIP
Depending upon set up at this point, other machines can go to the LAN ports of the router or the VOIP switch.

How does that procedure you mentioned help me identify which process is using the MOST network resources? Or is there even such a thing as "network resources" ie.e something that, when overtaxed, slows down a computer's link to the web, much like an antivirus program can slow down the computer by overtaxing RAM or CPU...

Your suggestion is to address which of my questions?
thx!
Actually, the netstat /a/o will show you all of your TCP and UDP connections both either in LISTEN or ESTABLISHED state. With as many ZoneAlarm events you are having, you should be able to see several connections in ESTABLISHED state which if you do not know what they are, block them, one by one if you have the ability in the router. Don't worry about blocking in Zone Alarm because the traffic is getting into the network at that point and you will not see any improvement.
If you have any ports on the router open, try disabling these one by one to see if you can identify which port is causing your issues. If zone alarm is reporting intrusion attempts in the quantity stated, you either have ports open on the router or another machine on your local network is the culprit. Just because it is registering intrusion attempts does not mean they are bad or otherwise hack attempts. Look at the details and determine where the are originating from, this may also give you some ideas of where to begin this fight.
A better mousetrap for this would also be http://technet.microsoft.c
Next is to make certain that the system in question has the latest drivers for the network adapter installed. A simple issue like a bad cable could also cause issues like this. Try swapping the cables around to see if the issue moves to a different system. Try disconnecting everything but the router and the one system, still have the issue? This eliminates any interal LAN issues. If it does go away, one of the other pieces of equipment internally are the cause. Plug one in at a time and test again.
A final thought is that the system itself may not be capable of processing the traffic fast enough. You might have the fastest processor out there and have relatively few services running in the background but the architecture of the system board or the compatability between the system board and network adapter may be in question. There may not ever be a real magic bullet to this problem.
At the end of the day, the only true way to determine network resource and usage is with a packet sniffer placed on the network to analyze the traffic. This is the only way to view the actual packet traffic taking place and determin the source and destination of the same.
Hope this helps,

i will give you the best ever effictive manual method
first go to the command prompt and write
netstat /o
you will see all the processes that is using the network with the process id write the process id and go to the task manager and go to the process tab and then go to the veiw choose select colomn and tick process id and press ok to see the pid beside the prosses name so you can recognize it or search for its name on the windows explorer and here is it done go ahead
