Public bug reported:
I'm in trouble with my notebook Acer Aspire E5-571G and its realtek ethernet
controller using the kernel module r8169, particularly at school when I'm
connecting with my Ethernet cable to its network. It just basically doesn't see
my cable, like it is disconnected, this problem came after I've changed it. And
I've find on the net how to fix it using ethtool `ethtool -s enp1s0f1 autoneg
off speed 100 duplex full`
Maybe this cable is maximum 100Mbps capable and the driver can't manage how to
get it working with a gigabit network, since with other (Gigabit) better cables
I don't have this problem. Also I don't have problems in Windows or with other
computers using the same cable. (Windows connection speed with this cable is
100mbit) I've tried also with a different computer using the same kernel driver
with the same LAN chip and the same problem happened. Since the realtek r8168
works flawlessly but it disconnects randomly I prefer using the one provided by
the linux kernel.
Using Ubuntu 4.2.0-29.34-generic 4.2.8-ckt3 Linux kernel.
Ubuntu 15.10 Wily
The network should be working with any cable
Seems like linux does not detect the 100Mbit cable on a 1000Mbit
network, don't know if on a 100mbit network it has the same problem.
