Ubuntu 16.04 not dynamically assigning an ip address to enp5s0

Question

I've done a fresh install of Ubuntu 16.04

When i connect another computer or Gigabit switch through the wired connection it fails to assign an ip address to enp5s0.

I understand i could configure a static ip but i would prefer to resolve this issue.

Answer 1

Thanks for all your help, however i've made the following progress.

I ran this command to check the model number of my Ethernet Controller

lspci | grep Realtek

The output

05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101/2/6E PCI Express Fast/Gigabit Ethernet controller (rev 05)

I then checked checked what driver the kernel was loading

lsmod | grep r816*

The output

r8169                  81920  0
mii                    16384  1 r8169

Seeing that they did not match i headed over to the Realtek website to get the RTL8101 Driver but they only have it for the 3.x, 2.6.x and 2.4.x kernels.

And so either I have to wait until Realtek release a driver for kernel 4.x or upgrade my hardware.

spacelander thanks for the link i learned from it

heynnema i assure you that you can connect direct and get an ip number, as I've been doing it for years and I'm sure with the correct driver I'll do it again.

Thanks & Regards Jonny
