Hey Guys,

I recently built a desktop and flashed Ubuntu(17.04) on it.

For some reason I am not able to get ethernet working on it. I have tried most the network manager hacks on the internet but with no success.

To add to the woes, the machine is currently not connected to internet and the ubuntu cli didn't have basic tools like ifconfig/ethtool installed.

The details of the build is as follows:

Computer Type: Custom Desktop build.

GPU:MSI - GeForce GT 710 2GB Video Card

CPU:AMD - Ryzen 5 1400 3.2GHz Quad-Core Processor.

Motherboard: MSI - B350 TOMAHAWK ATX AM4 Motherboard.

RAM: Crucial - 8GB (1 x 8GB) DDR4-2133.

PSU:
Thermaltake - VO545A1N2U ATX Mid Tower Case w/450W Power Supply. SSD: Silicon power 120GB SSD 3D NAND HDD: WD Blue 500 GB Internal HDD ‑ 3.5" ‑ WD5000AAKS Operating System & Version: Ubuntu 17.04

Chipset Drivers: Whatever came with the board. Nothing new installed Background Applications: NA

Ethernet adapter: realtek 8169 I believe.

Any Help will be greatly appreciated. Its a shame that in this day and age, a fresh Ubuntu build does not work out of the box :(

have you ever seen the networking hardware functioning in any way? if not, make sure its not a hardware issue. i like to load up "known good" live iso's, and see that the hardware isnt broken (even when its brand new hardware). there are lots of other live iso's that are not ubuntu based, if you feel its something specific about ubuntu that is causing the issue. if you were to download and run a live fedora iso, if the wired network is functional or not, under that live iso, would help determine where the problem is.

could be, something in the bios would allow you to test the connection,

when you say "flashed", what does that mean? is that a typical ubuntu installation? if so, can you get networking up in that live environment? if not, did you flash something "custom" that may have a kernel, or some other piece that would be preventing support for the NIC..

when you say "realtek 8169 i believe".. is it? motherboard manufacturers may swap out parts between revisions. how are you determining what you have? from your "flashed" os, or a live iso are you able to see the hardware listed using any commands from the terminal like "lspci" or "ifconfig", etc?...
