2.5Gbps USB Ethernet Adapter

The GCROWN adapter adds a 2.5Gbps wired network port to laptops or desktops through a single USB connection. It targets users who need faster and more stable links than standard Gigabit Ethernet or Wi-Fi can provide. The hybrid 2-in-1 cable terminates in both USB-C and USB-A plugs so it fits modern and older ports alike.

Upgrade From Gigabit Ethernet

This adapter doubles the throughput of a traditional Gigabit Ethernet adapter when paired with a 2.5Gbps-capable switch or router. The speed increase is worthwhile for large file transfers, high-resolution video calls and low-latency streaming. Existing Cat 5e cabling supports the 2.5Gbps signal, so no rewiring is required. Full performance needs a USB 3.0 port.

Broad OS Support With Driver Notes

Windows 11, 10, 8.x and 7, macOS 10.7 and newer, iPhone 15 models and Linux Kernel 3.2 and newer are supported. Driver installation may be needed on older operating systems or kernel versions, and some macOS features require the driver. Buyers who need plug-and-play operation on very old systems without driver access should consider alternatives.

Questions about this item

What USB ports does the hybrid 2-in-1 cable fit?

The cable has a USB-C connector with a built-in USB-A adapter so it plugs into either port type on your laptop or desktop.

Which driver step is most often missed on macOS?

After plugging in, you must download and run the macOS driver installer before the adapter will pass traffic; the device is not fully functional with the in-box kernel driver alone.

When will the RJ45 port or cable need replacement?

Replace the patch cable if the clip breaks or the conductors corrode; the adapter’s RJ45 jack is rated for many insertion cycles and typically outlasts several cables.
