USB 3.0 Gigabit Ethernet adapter

The Enfain U3.0 adds a wired RJ45 network port to any device with a USB 3.0 socket. It uses the RTL8153 chip and requires no external driver disc; Windows 8 and later install the necessary software automatically. The 20 cm cable keeps the dongle close to the port for a tidy setup.

Replaces a missing or faulty onboard Ethernet port

When a laptop or compact PC lacks a built-in RJ45 jack, this adapter restores a stable 10/100/1000M connection without opening the case. The jump is worth it whenever Wi-Fi is unreliable or a wired link is required for secure networks. It also serves as a quick fallback if the motherboard controller fails.

Limited by USB 3.0 bandwidth and cable length

The link tops out at the gigabit rate negotiated over the USB 3.0 bus, so throughput cannot exceed that interface ceiling. The fixed 20 cm lead restricts placement to the immediate vicinity of the host port. Buyers who need more reach or multi-gigabit speeds will need a different solution.

Questions about this item

How much clearance does the 20 cm cable need behind the USB 3.0 port?

The adapter has a 20 cm black cable, so allow at least that length behind the USB 3.0 port for a relaxed bend radius.

What driver step is required on Windows 8 or later?

Windows 8 and newer install the RTL8153 driver automatically; no CD or manual download is needed.

When should the adapter be replaced if the RJ45 link drops to 10 or 100 Mbit/s?

If the negotiated speed falls to 10 or 100 Mbit/s on a known 1000 Mbit/s link, the RTL8153 chip or cable may be failing and the unit should be swapped.
