Hi,
I am having trouble with my laptop getting an IPv4 address through a wired connection. I had the issue with WiFi too but I fixed it by adding noipv6rs and noipv6 to the dhcpcd.conf and disabling IPv6 configuration at the Network Manager.
I tried to disable the IPv6 configration for wired connections through Network Manager but with no luck.
ifconfig outpout:
enp0s25: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500

Any suggestions on how to fix this?
Thank you.

to the dhcpcd.conf and disabling IPv6 configuration at the Network Manager
Are you maybe concurrent network daemons?
systemctl list-unit-files --state=enabled
Short version: don't. You wired ethernet has a carrier, but no lease at all and that likely is because the concurrent daemons knock each other out.

So if I disable Network Manager or dhcpcd it will be fixed?

"Potentially" - depends on
1. how many more services you're running
2. whether there're further issues
Limiting the amount of NIC controlling services to 1 is however mandatory, everything else will cause trouble for sure.

Sorry for the late reply. I deleted Network Manager, I lost all internet connection and I didnt know how to fix that other than downloading it from an other computer and installing it offline to my laptop.
The reinstall fixed the problem though. Not for the long though probably I am sure. I really need to learn how networking works...
Thank you
