Don't you think that you have enough of a clue there :P That eno52 is,
as you can see ethernet card, of course it will work when you connect it
with ethernet cable. If you want it to work with wifi, that is another
story. What is your wifi card, do you have something starting with w in
the output of ip addr show? What is the output of the lspci -v | grep -i
-A6 net?
