Hello, I don't know if this is the right forum for this but...

I have internet activity lights flashing on my router but I can't find anything happening. I tried task manager but still see nothing.

Is there a place I can check or a program I can use to see what is being used or downloaded?

It seems like I should know this but I cant remember.

Any help would be appreciated.

Thank you

Network Traffic Monitoring Tools:
Online Port Scan allows you to scan individual TCP ports to determine if the device is listening on that port.
Shields Up is an online port scanning service used to alert the users of any ports that have been opened through firewalls or NAT routers.

There are third party utilities that will allow you to manage, block, and view detailed listings of all TCP and UDP endpoints on your system, including local/remote addresses, state of TCP connections and the process that opened the port:Caution: If you're going to start blocking ports, be careful which ones you block or you may lose Internet connectivity.

Activity lights could be nothing more than 'keep alive' packets to maintain your connection. It is not necessarily an indication of any sort of payload being downloaded or uploaded. In fact lack of activity lights with your router would be a 'bad thing'.

However to verify that nothing nefarious is happening use some or any of the tools suggested by quietman7.

I downloaded the microsoft network monitor but, I have no idea what I am looking at. It shows something is going on 1 to 3 times a second but, don't ask me what. The lights are flashing normal now but, earlier they were flashing like I was downloading something. Yahoo mesenger shows up a lot and svchost shows up a whole lot. As far as the rest of it I am reading french.

It is now starting to show names of programs that are using the internet. I think it was AVG anti-virus downloading an update on my other computer that was making all the lights flash. I am still going to keep using the network monitor.

Thanks quietman7. I appreciate your quick response. That is why I come here with my problems.
