Realtek 8139 ethernet interface running but does not connect












0














I have an old SONY Vaio PCG-FR285E laptop running Lubuntu 18.04. I think I'm close to get the network interface working, but I can't find what is missing (my network setting abilities are closed to zero!).



The network interface is:



$ lspci | grep Ethernet
00:0c.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8100/8101L/8139 PCI Fast Ethernet Adapter (rev 10)


I know the hardware is ok because I have installed Lubuntu through PXE network booting from a FOG server.



I had to blacklist 8139cp so that it would be claimed by the kernel:



$ lsmod | grep 8139
8139too 32768 0
mii 16384 2 usbnet,8139too


(usbnet is enabled because I use my smartphone to share internet through usb)

Still, Network manager says "device not managed", and it definitely does not connect. I have checked that the cable and the broadband router are ok, as another laptop does connect without trouble.



Some more information:

I'd love to get it working, if possible automatically at boot as it should be.



Any help greatly appreciated !

      Still, Network manager says "device not managed", and it definitely does not connect. I have checked that the cable and the broadband router are ok, as another laptop does connect without trouble.



      Some more information:



      $ dmesg | grep -e eth0 -e 8139
      [ 0.048233] pci 0000:00:0c.0: [10ec:8139] type 00 class 0x020000

      $ cat /etc/network/interfaces
      # interfaces(5) file used by ifup(8) and ifdown(8)
      auto lo
      iface lo inet loopback
      auto enp0s12
      iface enp0s12 inet manual


      I'd love to get it working, if possible automatically at boot as it should be.



      Any help greatly appreciated !
