Has anyone had this issue while running thousands of chromium tasks or high intensity workloads? I run a monitoring software that monitors thousands of sites at once. To be specific headless chrome browsers. So I run thousands of chromium tasks and my computer internet disconnects but my other devices are fine like my phone WiFi and TV internet. I have a MSI Tomahawk Z490 i9 10900k and 48 GB of RAM. Not sure if it’s my motherboard but I see online that the MSI Tomahawk has a lot of driver issues. Does my network card not handle this amount of load? I’m connected via Ethernet. I have an Eero Pro 6 and it should be more than capable of handling this many tasks not sure if it’s my router but if it was my other devices would also disconnect.

Update your post to include full system hardware specs and OS information.

Windows 10?

Look in Reliability History and Event Viewer for error codes, warnings, or informational entries that correspond with the disconnection times.

Look in the Router's logs (if available and enabled). The router may be noting some connection issue(s).

I see a few error codes in the Event viewer here they are:
The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
{2593F8B9-4EAF-457C-B68A-50F6B8EA6B54}
and APPID
{15C20B67-12E7-4BB6-92BB-7AFF07997402}

TCP/IP failed to establish an outgoing connection because the selected local endpoint was recently used to connect to the same remote endpoint. This error typically occurs when outgoing connections are opened and closed at a high rate, causing all available local ports to be used and forcing TCP/IP to reuse a local port for an outgoing connection. To minimize the risk of data corruption, the TCP/IP standard requires a minimum time period to elapse between successive connections from a given local endpoint to a given remote endpoint.

A request to allocate an ephemeral port number from the global TCP port space has failed due to all such ports being in use.

Intel(R) Ethernet Connection (7) I219-V Network link is disconnected. <-------This is why I lost connection. My NIC disconnecting now sure why.

I don't see anything wrong with the reliability monitor.
The concern I saw is from the Event Viewer where the Intel I-219V shut down.

Network link disconnected is almost always a hardware issue. I would try a new cable being sure to use a quality cat5e or better cable that is pure copper and has wire size 22-24 (no flat or thin).

The other error you see indicates a problem with the software you are running. You are opening so many session so quickly without properly closing them that you run out of ports. In some ways I am surprised you have not overloaded your router since it has tables of all these open ports also. Hard to suggest something. What you are doing is very close to denial of service software but in this case you are denial of service yourself.

I had switched over my ethernet port to a different network port. I have a 1G and 2.5G ethernet port. I am now using the 2.5G I am still having the same issue today. Would this problem be the computer hardware/software limitation or my modem/router limitation?

A request to allocate an ephemeral port number from the global TCP port space has failed due to all such ports being in use.--This is another warning

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID

This security permission can be modified using the Component Services administrative tool. ---Another one

Found this online, would this free up the ports?
