The TRENDnet TU2-ET100 is a pocket-sized USB 2.0 to Fast Ethernet adapter that gives any USB-equipped machine a wired 10/100 Mbps network port. That makes it a practical fix for older desktops, MacBooks, Chromebooks, and notebook PCs whose onboard NIC has failed or was never there in the first place. The adapter runs at Full Duplex 200 Mbps throughput on a 10/100 network, and its attached 10.5 cm (4 in.) flexible USB cable keeps the dongle from blocking neighboring ports or dangling off the chassis. Driver support is the reason this TRENDnet adapter keeps showing up in retro and legacy build…
