TP-Link TX201 2.5 Gigabit PCI Express Network Adapter | Low-Profile & Full-Height Brackets

Your PC's 1 GbE port is the ceiling. Everything else on the network can do more, but that one card holds you back. The TX201 drops into a spare PCIe x1 slot and pushes 2.5 Gbps through a single RJ45 port — no new cabling, no new switch. It auto-negotiates down to 1G or 100M if the other end can't keep up, so you're never stranded on an existing setup. Ships with both full-height and low-profile brackets for whatever case you've got. Windows and Linux supported out of the box
