StarTech USB Type-C to Ethernet adapter with 2.5 GbE RJ45 port for multi-gig wired networking

Move beyond Gigabit bottlenecks with a compact USB-C Ethernet adapter built for modern endpoints. The StarTech U2GA-USB-C-ETHERNET adds 2.5 GbE wired networking through a USB 3.0/3.1 Type-C or Thunderbolt connection, giving laptops, tablets, and small-form-factor systems a faster path to file transfers, imaging, and cloud access. Its single RJ45 port supports 10/100 Mbps, 1 GbE, and 2.5 GbE links, so it can negotiate cleanly across mixed infrastructure while preserving headroom on multi-gig switches. Realtek-based support for 16K jumbo frames, Wake-on-LAN, and VLANs makes it suitable for managed environments where network policy and remote access matter. USB bus power keeps deployment simple: no external adapter, no extra brick, no desk clutter. The included USB-A converter extends compatibility for older ports, while support for Windows, macOS, Linux LTS kernels, and iOS broadens fit across enterprise fleets. For teams standardizing on USB-C hardware, this adapter delivers a practical upgrade path with the network performance needed to justify the move.
