    USB 3.0 to 2.5 Gigabit Ethernet Adapter, USB-A to 2.5GbE Multi-Gig Network Adapter for Windows, macOS & Linux Aluminum, RTL8156BG, Backward Compatible 10/100/1000/2500 Mbps (NT-UA25)

    • INSTANTLY ADD 2.5GbE OVER USB-A: Plug into any USB 3.0 (Type-A) port to add a 2.5 Gigabit Ethernet port up to 2.5× faster than Gigabit and far more stable than Wi-Fi. Auto-negotiates to 2.5G / 1G / 100M. For the full 2.5Gbps, use a 2.5G router/switch and a CAT5e (or better) cable.
    • PREMIUM RTL8156BG CHIPSET: Built on Realtek's RTL8156BG controller for low-latency, low-CPU performance that fixes the issues found in earlier chipset revisions stable and reliable during sustained transfers.
    • PLUG-AND-PLAY ON WINDOWS, macOS & LINUX: Driver-free on most systems. If Windows connects slowly, run Windows Update for the latest Realtek driver; Linux uses a recent Realtek r8152/r8156 kernel driver. The USB-A cable is integrated nothing extra to carry.
    • FULL SPEED AT A DISTANCE: Compliant with 802.3bz / 2.5GBASE-T for up to 2.5Gbps over 100 m of CAT5e or better. Backward compatible with 1GbE and 100Mbps networks and USB 2.0 ports. Supports Wake-on-LAN and PXE boot.
    • ALUMINUM & TRAVEL-READY: A rugged aluminum housing doubles as a heatsink for cool, stable performance, in a compact bus-powered design with status LEDs. Note: this is the USB-A version for a USB-C port, choose the SABRENT NT-25GA.

    • This is the USB-A version — it plugs into a standard USB-A (USB 3.0) port. If your laptop only has USB-C, choose the SABRENT NT-25GA (USB-C to 2.5GbE) instead.

    • Make sure it's in a USB 3.0 (usually blue) Type-A port — a USB 2.0 port caps it near 1Gbps. You also need a 2.5G router/switch and a CAT5e (or better) cable; it auto-negotiates down if any link is slower.

    • Plug-and-play on Windows and macOS. If Windows is slow, run Windows Update for the latest Realtek driver. On Linux, use a recent Realtek r8152/r8156 kernel driver (newer kernels include it) for stable 2.5G.

    • Use CAT5e or better for the full 2.5Gbps at up to 100 m. Older or damaged cabling can force a slower link, so CAT6 is a safe choice for longer runs.

    • Yes, on a USB 3.0 hub or docking station. For the full 2.5Gbps the hub/dock must provide a 5Gbps (USB 3.0) data port — a USB 2.0 hub will limit speed.
