### ⭐⭐⭐⭐⭐ H!Fiber 2.5Gbase-T PCIe NIC with Realtek RTL8125 Chip, 2.5Gb works GREAT with Linux, buy this.
*by J***N on 21 September 2025*

Using Proxmox, which rides on Debian 12(?) Linux. This works right out of the box with NO ISSUES at all. Full speed, I have 2 of them that form my storage network, while a normal gig card talks to my main network. Would buy again and every time from this point on. Might sell and bench this one and go for the 10g model they have.
