@Domenic: we’ve received your return. For the record, here is the diagnosis result: I’ve tested the controller right away and I honestly could not find any network related issue at all. I’ve used Linux’s ping command to continuously ping it for 10 minutes and there is not a single lost packet. Also, this is going through a TP-Link WiFi adapter, which generally performs less reliably than direct wired connection. So I assume the issue you encountered is specific to your network setup. Without replicating the setup, I honestly can’t reproduce the problem. Thanks for understanding.
