The little mini-pc I'm using to test Proxmox unfortunately only has a single 1gb ethernet port. Since most of my network is 10 gig, I decided to see if I could at least get 2.5 gig working, since this box doesn't have thunderbolt and those adapters are super pricey anyways.

I picked up this Anker adapter from Amazon: Anker USB C to 2.5 Gbps Ethernet Adapter

All I had to do was plug it in and create a bridge with it within Proxmox. I assigned an adapter to my Windows host (using the VirtIO Paravirtualized driver) and installed the driver from the Qemu guest agent ISO: https://pve.proxmox.com/wiki/Qemu-guest-agent

And that was that. I now have 2.5 gig ethernet for Proxmox!

@malcolm-r Thank you for testing the USB-C to ethernet adapter. This will be a great resource for those looking to add 2.5 GbE to their mini PCs. I am assuming this is a realtek chipset like my 1 gig adapter, so should work (ironically) with VMware as well.

@malcolm-r are you starting to run more workloads in Proxmox for testing? Curious how you are liking it?

@brandon-lee not a ton, yet. with 2 big esxi hosts i just don't have a big use case right now. i am, however, about to spin up an Ubuntu VM to transfer my torrent client to. i'm seeing some performance issues running it in docker, so i'll try a VM next and see if that helps.

I did the same thing with an HP z640 and my Synology DS220+ It was definitely more complicated on DSM7

@louie1961 I would be interested to know how you do this on a Synology device. Was it a chore on the driver side?

I followed this guide from the folks over at NAScompares . I am using this NIC, mainly because it was cheap on Amazon. https://www.servethehome.com/ult-wiiq-usb-3-to-2-5gbe-network-adapter-review/
