Why dhcp worked during install and not after?

Hi,

I downloaded 2 different server distributions to setup my own cloud server at home.

The first one, during installation, did not connect to the network. I thought it was a network card drive issue so went with the alternate install download. On the 2nd try, the network worked fine, DHCP grabbed an IP address, and installation went fine. Then after rebooting to start using the server, I could not do anything network related: ping, network browsing, etc. Thinking it was distribution specific, I downloaded Fedora Server version 29. Same thing: during install DHCP worked fine but after rebooting to start using the server, no network connectivity.

I have searched the 'net for my issue and nothing's turned up even remotely related to what I'm seeing.

I hope someone here can help and point me in the right direction. Also, I'm hoping someone actually says something and my question won't sit unanswered for days.

Thank you.

No sure this is your case as you did not mention the installation media you use, but on some installation on anaconda you must set to auto start the network device on boot maybe that is way you have that issue.

For both distributions, I downloaded the ISOs and used Rufus to create a bootable USB stick.

Also, I've done many distribution installs, desktop and server versions, where network is fine both during installation at the Live mode and after installation when running from the hard drive. This seems to be something unique or security related. Or I may have found a bug.

I have found that on Centos 7 minimal install and old Fedora, but I think it was fix on 29.

I wish it was possible to upload or attach a picture. nmcli shows no connectivity. So I connected a USB to Ethernet adapter and right away it was configured and connected to my network. I think it's something with the built-in network port of the motherboard. I'm going to do some specific searches for that hardware and linux.
