Compact USB 2.0 Ethernet Adapter

The TeKit NTR20254L adds a wired RJ45 port to devices lacking built-in Ethernet, such as ultrabooks, MacBook Air models, tablets, or legacy consoles like the Wii and Wii U. It draws power directly from the USB bus so no external adapter is required. The 0.5 ft cable keeps the dongle close to the host port for a tidy desk setup.

10/100 Mbps Over USB 2.0 Bus

The ASIX AX88772 chipset delivers full 10/100 Mbps Fast Ethernet throughput across the USB 2.0 interface and its 480 Mbps bandwidth ceiling. Link and Activity LEDs provide immediate visual confirmation of connection status. It handles IPv4 and IPv6 traffic on 10BASE-T and 100BASE-TX networks with Wake-on-LAN, Full-Duplex and Auto-MDIX support.

Broad OS Support With Clear Limits

Compatible with Windows 10 through XP, Mac OS X 10.6 to 10.11, Linux kernel 2.6 and 3.x, and Chrome OS for plug-and-play networking. It does not support Windows RT or Android devices, so buyers needing mobile or ARM-tablet connectivity should look elsewhere. The shielded cable and hot-swap capability suit both desktop and portable workflows.

Questions about this item

Will the .5 ft cable reach from a rear motherboard USB 2.0 port to a desk-mounted switch without strain?

The adapter includes a .5 ft tether; if the host port and switch are farther apart, add a standard Ethernet patch cable between the RJ45 jack and the switch.

Which LED pattern confirms the AX88772 chipset has negotiated a 100 Mbps full-duplex link?

A solid Link LED plus a blinking Activity LED indicate an active 100BASE-TX connection; the adapter supports both full-duplex and half-duplex modes.

Does the box contain a driver CD for Windows 8.1 or must I download the ASIX AX88772 driver separately?

No driver media is included; Windows 8.1, 10, and 11 install the ASIX driver automatically, while Mac OS X 10.6 through 10.11 and Linux kernel 2.6 or 3.x use built-in support.
