I have a pci wifi, a usb wifi and a built-in ethernet on my pc. They all stoped connecting and give error Activation of Network Failed. I don't expect it to be a hardware issue.

I tried:

ip link set LINKNAME up

But that did not help, as when I check "ip link" the LINKNAME status is DOWN.

Here is journalctl output after trying to activate the Ethernet (just 46 lines): another link:

What is the problem? Also the pc hangs for a few seconds and cpu usage increases after trying to connect and before giving the error.

IPv4 and IPv6 both set to automatic.

This is a long shot, but ... is your etc/resolv.conf locked? This happened to me a while back, I had to sudo rm the file (it was regenerated on reboot). If you've changed network settings from defaults and/or running a server, this may be a bad idea. I'm just using Fedora for a desktop.
