I have just installed Linux Mint Cinnamon on a second SSD.
My grub files are on my first SSD containing Windows 10 OS. I boot up using UEFI Ubuntu choise in the boot menu.
In Linux, the Network Manager does not see my Ethernet hook-up. I have searched for answers, and they all show a Network manager and the ability to pick out a network. Mine does not do that.
Also the security choices are none that I have ever seen.
I suspect my new hard drive does not see my Ethernet hook up.
As a side note, I noticed, when I booted up Windows, that the time had changed - by 6 hours. I had not been booted up to Linux Mint for more than 30 minutes.

Any help would be appreciated.

By "my new hard drive does not see Ethernet hook-up", you mean your newly installed Linux Mint installation?

You need to make sure the ethernet card/interface that the machine you have installed Linux Mint on, is supported with a Linux driver. But first we need to know which one your machine has.

Run the following command and post the output of it:

Use CODE tags when you post the output.

I will use that command when I go into Linux next and send the info to you.

I just had the feeling way the the hard drive is installed was the problem, although I was able to format it easily. Also all my other drives and storage devices are available with Linux. My clock time in W-10 OS changes as I go in and out of Linux, meaning the board's clock time is not being read, or Linux depends completely on Internet time.

I was thinking as new as this Linux Mint is (18.2) the bugs would be out.
Thanks!

I'm still not understanding what the hard drive has to do with your issue. If you can access it/format it, this means that it's working. We need to once again know which ethernet card your machine has, and then we can go from there.

So, when you get on your Linux machine with the issues, you can post the output for the command in my last post above. Remember to use CODE tags when you do, as it's much easier to read with CODE tags.

Thanks;

What is a code tag?

I have been studying Linux Command Line basics from this site. Kinda fun. I have been around computers since 1974, learned Wang, Fortan 4, DOS, etc. I was the first person to do the statistics of his graduate degree with a computer at the U of Idaho. It was about as big as a 3 bedroom house:<) I have a friend who uses Linux, and it sortof started me up again. He gave me the Mint image.

Thanks again
Get back to you later today.

See my posting signature - it's the first link in it.

OK, here's what I copied off the command line;

[code]00:19.0 Ethernet controller: Intel Corporation Ethernet Connection I217-LM (rev 04)[code]

The net in Ethernet was red txt.

I also copied the ifconfig;

[code]eno1 Link encap:Ethernet HWaddr 34:17:eb:dc:91:53

I hope this is helpful.

Thanks!

If you have an Intel ethernet card, there shouldn't be any driver problems. Actually I've never heard of anyone having a driver problem with wired ethernet. It's much more likely to be a naming problem. A lot of distros have switched to positional naming rather than the old eth* convention. The ifconfig command (or ip link show if you don't have ifconfig) will show what your ethernet interface is called.

Oops! I see you've already done that and your ethernet is eno1. That means it's not a card, it's onboard. It also proves that the correct driver is loaded. Now check your nm config files to see if nm calls it by the same name.

Thanks!

How do I do that? I typed nmconfig, nm config and nm - not a command. I presume nm to be network maintenance - do I look under Network?

Thanks again!

You need to look nm's configuration files. I'm not familiar with nm, but it seems to have a built-in connection editor. See for example this article: https://help.ubuntu.com/community/Ne...tings_in_GConf.

beefman,

No IPv4 address is assigned to your eno1 interface.

Go into your Setup/BIOS and if it is not already enabled, Enable Onboard LAN.

That, my friend, did it. After enabling the onboard LAN the Mint Network Manager saw the whole setup!

Thanks a Bunch


Well, one time anyway. When I rebooted into linux the second time there was no connection. I checked the Bios and they were still set to enable LAN. I hard booted and checked them again - they were still enabled but Linux has no Ethernet connection any more. DARN!

beefman,

Very puzzling.

Try some of chili555's suggestions on this link:

https://ubuntuforums.org/showthread.php?t=2280968

Well, I did what I could turning off and on switches. Some were available, some not.
I also went in and "touched" the NetworkManager globally managed file, and checked to see that it was empty.


What is amazing is- that I had an immediate internet connection in Linux and can't seem to get it back. I tried disabling the onboard LAN again, hard booted, and swithced everything back, and it still would not connect. It shows the device MAC address every time, but is non-respondent to adjustment.

I ordered a USB Wireless connector, as one respondant stated that his Ethernet in Linux saw his instantly.

I'll let you know if that works.

It's not worth having Linux without the Net.

Thanks for your efforts;
