November 5, 2025Nov 5 download speeds are in the gutter.... I'm thinking I need a separate Intel NIC. Can someone help me confirm? Tried a different CAT5 cable, tried bypassing my 5-port switch as well. Was going to try updating my BIOS, but won't have time for a while to get to it.Just ordered two cheap NIC's to try out, but are there other suggestions for reliable NIC's these days? direwolf-diagnostics-20251104-1936.zip
November 16, 2025Nov 16 Author Tried swapping in a NIC instead of my onboard one and the problems are persisting. What I figured out is that the internet issues are only in my VM, not the rest of my Unraid setup. But, if I download anything inside the VM, it slows down everything (even my Docker Containers). But, the Docker containers can handle any type of bandwidth without slowdown as long as the VM is not using any bandwidth.Anyone have any ideas?
November 17, 2025Nov 17 Community Expert Don't see any obvious issues in the diags, you could try passing through the extra NIC to the VM for exclusive use, and see if that helps.
November 19, 2025Nov 19 Author Didn't seem to work.... Making sure I did it correctly, i switched my main NIC in network settings to have a different one in eth0, then set the separate NIC as eth2 (my onboard NIC has dual ports and the second one took up eth1). Then i changed the network interface in my VM configuration to use eth2 instead of br0.Tried it the other way around too with my separate NIC for my Unraid side of things and the onboard NIC for my VM. I can't seem to figure this one out.
November 19, 2025Nov 19 Community Expert I meant pass through the device using vfio to the VM, so it has direct access to it,Unraid will no longer see that NIC.
November 20, 2025Nov 20 Author Tried that out and didn’t have any luck…Not quite sure what’s going on…In the VM, the card says 100Mbps, but the br0 that was set up in the configuration of the VM shows 1000Mbps (in terms of network card properties). Speedtest.net gives me 8Mbps down and ~50Mbps up. But my librespeed container shows 2,500Mbps….
November 20, 2025Nov 20 Community Expert I realize you swapped cables already but those symptoms sure sound like a badly crimped connector. I do not think unraid is causing the problem.
December 13, 2025Dec 13 Author Made a few more new cables and tried them out. Same issues. Except now the speed drops if the VM is running, not just when a download is going. I have no idea how to proceed. Nothing has changed software-wise since before the problems started. Cant even download Docker container updates without the whole server bogging down to slower than a crawl. direwolf-diagnostics-20251212-2117.zip
December 13, 2025Dec 13 Community Expert Only other thing I can think is to disable bonding. Hope you isolate this and then share the fix.
