The SD-ADA24064 is based on Realtek's RTL8156 controller, which supports 2.5GBASE-T and on down, all over standard Cat5e cabling. The Realtek chip supports such features as 9k Jumbo frame support, auto MDI-X (crossover detection and correction), and IEEE 802.1Q VLAN. Since some of these capabilities require OS support, the dongle comes with drivers for Apple MacOS (10.12 and newer), Microsoft Windows 7/8/10, and Linux (kernel 3.2). OS SUPPORTED: Up to Windows 10 Mac OS 10.8 - 10.15 Linux Kernel up to 5.6
