Subject: Trouble with Realtek Ethernet RTL8111/8168/8411 (rev 12)

Hello everybody,

i was directed here by members of the arch forum where i have reported
my problem and where the information provided below is perhaps more
readable:
https://bbs.archlinux.org/viewtopic.php?pid=1455220#p1455220

if i shouldn't have written to you plz feel free to let me know and
plz help me adressing this to the right channel.

my situation is the following ... [BlogPost]

i plugin the ethernet cable but network manager still shows "no cable
attached" and no ip adress information ...

neither the lights of the ethernet port of the router nor the ones of
the laptop light up ...

here are my details:
i have the same problem under arch in kernel 3.16 and 3.14 and under
ubuntu 14.04 kernel 3.13

$ ifconfig

the computer that has the problem is a laptop and i dunno why there
are 2 Realtek Entries ... it definitly has only ONE ethernet port!

((installing aur r8168 and loading the module ofc did not fix the
problem as suggested by others ...))
