Cable unplugged even if plugged Realtek RTL-8110SC/8169SC


Hello to all.

I have just installed the system (Manjaro XFCE) and I have one, major, problem: it says that my network cable is unplugged, even if it's plugged.

I have a Realtek RTL-8110SC/8169SC Gigabit Ethernet and with Windows it works with no problem.

If I do ifconfig in the terminal, I get:

Code:
enp7s1: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether 14:da:e9:21:fd:bf  txqueuelen 1000  (Ethernet)

        inet 127.0.0.1  netmask 255.0.0.0

        TX packets 384  bytes 30176 (29.4 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
The "enp7s1" should be my card (I recognise the MAC), but usually isn't it "ethX" ?

Also, here is the output for lsmod command:

I already tried to change the interface from "down" to "up", but it remains down without displaying any errors. How can I solve this?

P.S: Excuse me for my english, of course.

looks like driver problem. You may try to download the correct driver from realtek and install it (sometimes it is not recognized properly)
