apalrds adventures | FIXING my USB3 2.5Gbe network adapters on Linux / Proxmox! @apalrdsadventures | Uploaded January 2023 | Updated October 2024, 2 hours ago.
Do you have a USB3 2.5Gbe network adapter (using the Realtek 8156 chipset) that doesn't work well in Linux? Well, the kernel has included the upgraded Realtek drivers for awhile now, but for some reason it needs additional udev rules to load correctly. It's a pretty simple fix and results in dramatically improved bandwidth (full duplex ~1.5Gbps and half duplex ~1.9Gbps), and functions properly with the correct driver.
Link to my blog post which includes the contents of the udev rules you need:

Here's the exact adapter I'm using for my cluster - I chose it because of the price and form factor, there are other options if you prefer USB-C or longer cables.
