4XEM USB 3.0 Gigabit Ethernet Adapter

The 4XEM 4XUSB3GIGNET adds a wired network port to any device with a USB 3.0 socket. It supports 10/100/1000Base-T speeds through a single RJ-45 connector. The adapter draws power from the USB bus and weighs 0.05 units. It suits laptops, desktops or embedded systems that lack a built-in Ethernet jack.

Replaces missing or failed onboard Ethernet

Use it when a system has no RJ-45 port, when the integrated controller has failed, or when a dock occupies the only native port. The USB 3.0 interface provides enough bandwidth for full gigabit throughput, so the upgrade is worth it whenever a stable wired link is preferred over wireless. It does not serve devices that only offer USB 2.0 ports.

Fits any USB 3.0 Type-A host

Plug the male USB 3.0 connector directly into the host or a compatible hub; no external power supply is required. The single RJ-45 female port accepts standard Cat5e or Cat6 patch cables. The compact form factor leaves adjacent ports free and adds negligible weight to a mobile setup. Buyers who need multiple additional Ethernet ports or fibre connectivity will need a different solution.

Questions about this item

Does the USB 3.0 male connector fit a standard USB 3.0 port on my laptop?

Yes, the Connector A is a USB 3.0 male plug that inserts directly into any standard USB 3.0 Type-A port.

What is the installation step people get wrong with this USB 3.0 to Gigabit Ethernet adapter?

Users often plug the adapter in before the operating system loads the correct driver, so connect it after the desktop appears.

Will the RJ-45 female port on this adapter wear out and need replacement?

The RJ-45 port is rated for many insertion cycles; under normal office use it rarely needs replacement.
