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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/254219967-h-fiber-com-2-5gbase-t-pcie-nic-with-realtek](https://www.desertcart.kr/products/254219967-h-fiber-com-2-5gbase-t-pcie-nic-with-realtek) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-08-14*
