The device most definitely has the RTL8366RB, as can be seen in the PCB photo here: https://www.redeszone.net/app/uploads-redeszone.net/d-link_dir-685_analisis_15.jpg > Do you have any suggestions? The DIR-685 has WAN + 4 x LAN and the WAN port is handled in a separate register from the LAN ports (suggesting it can also do an optical line) so I think it's 4 + 1. Yours, Linus Walleij
