Hello @MD2020 — Thanks for the detailed report!
Sorry to hear about the troubles you’ve experienced.
I usually like to mention that we’ve tracked a number of issues to in the past to managed switches(examples: here, here, and here).
The simplest way to confirm whether the switch (or its settings) are contributing to these symptoms would be to temporarily test with the switch removed from your network. Whether things improve or not, the results of that test would be a great data point.
I would also recommend enabling flow control on the switch, as we have seen that settings resolve a number of issues for other users in the past.
May I also ask that you confirm the following:
- Since you started experiencing this behavior, have you tried rebooting your networking hardware and remote devices?
- Do you have any antivirus software that could be contributing to network connectivity issues?
Regards,
Dylan
