I have some updates. The cable works on Windows XP with Atheros AR8121 PCI-E network card.
In windows 7, with Realtek RTL8101 PCI-E network adapter, doesn't work and have exactly the same behavior with Windows 10 running a Realtek chip using PCI-e. (seems like the cable isn't connected properly, keep trying to identify connection). Also checked with another windows10 machine with the same results.
All drivers are updated and are the latest available. The other end of the cable is connected to a router/modem of ZTE (ZXHN H108N V2.3) running modulation ADSL2+
I'm having a networking problem. I'd like to post the Network Info file but I use a Hosts File to block websites. It comes out a really big file. Would that be Ok to post or should I deal with all of the Hosts entries first.
