Hey Everyone, I’m having a bit of trouble fixing an issue with ethernet on a little Intel NUC we have Rocky 9 on. By default, onboard WiFi works perfectly but ethernet doesn’t and after checking with ethtool the reason looks to be that Half/Full Duplex speeds aren’t setting themselves automatically and instead show a value of “Unknown!”.
If I set them manually with ethtool ethernet immediately starts working, but the problem then is that on reboot the settings are lost and I have no ethernet again without manually setting them. I tried changing configs at /etc/sysconfig/network-scripts/ifcfg-[device_name] but it doesn’t retain the changes on reboot. I get the same behavior if I make changes through nmtui as well.
I need the ethernet to work on reboot without manual intervention; what am I missing here? Thanks in advance for any help!
