Well, when I got my RPi3B+ all was gud as it should be(probably). But now my Ethernet port just don't work. Many distros just don't shows eth0 (or neb24dfaw or how it...) (like with ifconfig -a) and "dmesg" shows this

And the most serious
[ 29.135899] lan78xx 1-1.1.1:1.0 eth0: no PHY found
But i found one distro that shows up eth0 at ifconfig -a But when i try to "sudo ifconfig eth0 up" or any orher way that what i get
SIOCSIFFLAGS: Input/output error
WELL, Idk what to do. (I AM SURE THAT ETH CABLE IS CONNECTED HOW IT SHOULD WORK)
(/etc/network/interfaces at distro w/ "working" eth0)
# interfaces(5) file used by ifup(8) and ifdown(8)
# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
Ah! Almost forgot. Lights at port don't work but at one distro (kali) at first boot it showed up.
