Hi everyone, thougtht I'd update the thread and close it out, since it seems to be working now. The cause was my network switch (HP ProCurve 1800), which I reset to factory settings. Thank you everyone for the help, I didn't think this could happen since I hadn't configured any of the features of the switch.

Hello, Lately I've been experiencing frustratingly slow (5-15mbps) network connection over ethernet. However what's strange is that only the inbound connection is slow, and outbound traffic is not affected. This has been reproducible using many different devices to connect to Unraid as well as a speedtest.net result from a VM running on the server. I'd also like to clarify that the server used to run at full speed in both directions, but the file transfers became slow more recently, though I can't pinpoint it to a specific release due to my set and forget tendencies. Troubleshooting I have tried so far: USB 3 NIC Bonding using USB nic and built-in NIC Upgrade to latest version of Unraid Disable Docker (I tested speed by copying file to a share) Disable VMs Run speed test using different PC The only thing I've considered but have not tried yet is running a different OS on this hardware, and doing a speed test from there Here are some screenshots from my speed tests: OpenSpeedTest result from another PC over LAN: Speed test from VM running on this server: Any ideas on how to troubleshoot this problem? I've looked at the logs briefly but don't have the background to separate any useful logs from the noise. Thank you in advance for the help! tower-diagnostics-20230118-2341.zip
