Question Possible data transfer disruption over LAN network in Windows 11 from Synology to Synology

[masterviper]

I have a LAN network using a gigabit switch that has 3 desktops and 1 laptop connected to it via hardwire and two synology bays connected to the same switch. this switch is connected to my modem/router using a MOCA adapter.

While I was using my laptop for work and transferring large files from one Synology to another (using network transfer via file explorer on my desktop) , i had two internet disruptions on my laptop (the ethernet icon on windows did not change when this happened). the network file transfer on the synology visible on file explorer on my desktop seemed to have continued.

Does this indicate that the network disruption was only from the ISP and did not affect my LAN switch and did not affect the synology transfer? I'm worried that if the file transfer were interrupted, it could have corrupted the data.

First I would recommend you look at using the NAS units directly so that you avoid the extra traffic that has to go from NAS1 to the PC and then from the PC to NAS2. You should be able to login to NAS1 and initiate a direct file transfer to NAS2. Your PC would only be the terminal access to NAS1.

A switch treats all the ports independently. In your case, lets say your laptop was on port 4 and your router on port 5. The traffic on ports 1, 2, and 3 (the two NAS and PC) never show up on ports 4 and 5. Is it possible that a long sustained transfer caused the switch to overheat? Yes, that is possible, but unlikely. Ethernet switches are very stable devices.

thanks. on the file transfer window on the windows desktop, is there a way to tell if there was a temporary network disconnect?

I would probably have task manager running and have the ethernet tab showing. You would see a period of zero activity.

Also regarding the temporary disconnects:

You might see some related error code, warning, or even an informational event being captured by Reliability History and/or Event Viewer.

Reliability History is user friendly and the time line format can reveal patterns.

Event Viewer requires more time and effort.
