Hello:
Original question:
https://superuser.com/questions/1332664/have-a-1-gbit-connection-but-i-not-all-devices-are-getting-1-gbit-speed-from-my
########################
I have 3 laptops and a 1 Gbit network connection to my ISP. But when I connect
my ISPs cable to the laptops ethtool link/speedtest precisely says:
Lenovo G500 with USB 3.0 Ethernet and OpenBSD 6.2 - 100mbit
Lenovo T400 with motherboard Ethernet Ubuntu 14.04 - 100mbit
Lenovo T560 with motherboard Ethernet Windows 10 - 1 Gbit
All the HWs support 1 Gbit connection.
The big question: Why cannot the Lenovo G500 and Lenovo T400 auto-negotiate to
1 Gbit? It is a 1 Gbit connection to my ISP, but I can only auto-negotiate with
1 Gbit with the Windows 10/T560 laptop.
Maybe I need cross-cable? The ISP I think has a switch at the other end.
This is the cable that I have from my ISP: https://i.stack.imgur.com/1rH37.jpg

the USB 3.0 Gbit ethernet to USB is cdce.
Anybody seen similar? What could cause the 100mbit connection instead of the
Gbit?
Thanks for any hint..
