Re: [PLUG] New Computer - No Ethernet
I had a similar one to this, I was setting up a NVR on Ubuntu server. I would put a jump drive in the server and boot off of it, all of the ethernet ports were visible, But the server install would not see them. I started looking to see what was missing ended up going into /etc/netplan/yadayada.yaml whatever name it gives your .yaml file) and found it was empty I ended up adding all of the needed bits and pieces and viola! there was working ethernet ports (I only needed 2 of the 4 on the server box) after I got the correct drivers in there I still had to add the port stanzas to the .yaml file.

Re: [PLUG] New Computer - No Ethernet
The specs for your board says the on-board NIC is an RTL8125, The driver was merged into the kernel about a year ago: commit 087f5b8758ae9f1b1968bc469bb3f5fae53e639b Author: Heiner Kallweit Date: Fri Aug 9 20:45:14 2019 +0200 net: phy: realtek: add support for the 2.5Gbps PHY in RTL8125 This adds support for the integrated 2.5Gbps PHY in Realtek RTL8125. Advertisement of 2.5Gbps mode is done via a vendor-specific register. Same applies to reading NBase-T link partner advertisement. Unfortunately this 2.5Gbps PHY shares the PHY ID with the integrated 1Gbps PHY's in other Realtek network chips and so far no method is known to differentiate them. As a workaround use a dedicated fake PHY ID that is set by the network driver by intercepting the MDIO PHY ID read. v2: - Create dedicated PHY driver and use a fake PHY ID that is injected by the network driver.

Re: [PLUG] New Computer - No Ethernet
CentOS 7 is pretty old (predates it by years) for your hardware - you need kernel 5.3 or newer for this to work properly. I am not sure if you can get this new kernel from CentOS 7 repositories. If you are used to CentOS - try CentOS stream or Fedora with newer kernel. Hope that helps, Tomas On Fri, 2020-12-11 at 16:53 -0800, Michael Barnes wrote: > Just got a new computer a friend built.

dmesg might give some clues. You might be missing a firmware for the NIC. I recall running into that on a server with some weird Broadcom NICs.

[PLUG] New Computer - No Ethernet
Just got a new computer a friend built. It is using a Biostar B550GTA Motherboard. I installed CentOS 7 in it, which went well. Problem is, I cannot get a network connection. I plug in the Ethernet cable and get a good light on the switch and a blinking yellow light on the jack in the computer. Cable verified good. If I do an 'ip a' it only shows io, no eth0. If I run the network utility nmtui, it does not show any Ethernet devices. I haven't worked on machines at this level in a few years, so I have likely forgotten all the obvious stuff. I went into the Motherboard setup and find nothing regarding enable/disable onboard Ethernet. Any ideas?
