About this tag
The 2.5GbE networking tag on WindowsForum.com covers practical discussion of 2.5-gigabit Ethernet in Windows desktops and home labs. A recent thread examines using an M.2-to-PCIe adapter to relocate a 2.5GbE Ethernet card in a Windows 11 machine, freeing a standard PCIe slot while keeping a direct connection to a home server. The key takeaway is that slot relocation and network speed are separate concerns: the adapter changes where the card sits on the motherboard, while bypassing Gigabit router ports is what actually improves throughput. Expect hardware-focused guidance for builders upgrading wired networking.
