Post #4449622

I've been trying to diagnose intermittent dropped packets, high latency, and WAN disconnects on a DSL connection at a remote site for months. The ISP has had many techs come out and try to fix it on their end. Today I ran some tests with disabling different equipment at the site to try and narrow down if something is inducing these issues upstream of the router. It seems like perhaps the #proxmox server or VMs or LXCs, the KVM dongle for remote access, the TrippLite PDU, or the five port switch all of that is plugged into might be to blame. However, this has been an intermittent problem so I'm not entirely convinced that I've isolated the problem. It could just be that when I was testing it was acting up in a specific way. I'm not physically at the site and my local support can't physically get to where the switch is (on top of a high cabinet) so I can't easily disconnect individual devices and the switch, while it has a management interface, is not the easiest to figure out what is plugged into what port. I think what I can do is move Pulse and Uptime Kuma LXCs to operate locally at the site rather than remotely. That'll take off some network traffic (the site is bridged to another site). I could also upgrade the switches at the site with something more user friendly. This is the site where I've blown up a half dozen switches and never could really figure out why until I kicked most things off the wired network and onto Wi-Fi. It could have been a ground loop between different buildings, a faulty device somewhere, or a bad cable. But also I don't want to throw parts at something that might not need parts. I've done packet inspection and nothing looks amiss. Nothing is trying to talk to the Internet in a weird way. No security issues that I've seen. Nothing rogue on the network. I'm not really sure what to do at this point. This is so perplexing. #networkAdmin
