I don't have here any wifi just Ethernet Cable RJ 45 Cat7
I will try find some solution how to fix that. Today I am little tired. Thank you @Aravisian for your sacrifice time and try help.
I wondering if my ethernet card using all or missing something to need best properly working?
What is output of:
ifconfig -a
Are you running Zorin in a virtual environment?
What you mean virtual box or something?
Yes, virtualbox or vmware?
Well when I Installed Zorin on external hard disk ssd then I suppouse this is not virtual. What is the sense installing good operative system on virtual box?
There are many good reasons to run in a virtual environment. Some are work related, some for testing...
But as that does not apply to you, let's move on:
What is your terminal output of:
ifconfig -a
?
billy@Zorin-16-Pro:~$ ifconfig -a

device interrupt 19??
It is normal. It is part of boot interrupt setting.
Your ethernet is not working at all? Or slow?
slow i think with fiber optic internet.
@Bourne I have no real idea what your problem is but I just did a websearch using:
"eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500"
and found this:
I do not know if that helps or is irrelevant.
i checked with tooleth0 and now I see all correct settings.
Can this subject now be marked as 
Solved?
Is it something to do with that Cmos clear you performed in another thread?
