No network controller?

Post by jhryu » Tue Jul 31, 2018 4:15 am

Hello, I am using Mint Linux 19.

I am using a network well, but suddenly it is not a network, it seems to me that I deleted some files related to the network some time ago.

I downloaded the driver from the manufacturer and installed it, but it does not work.

So I tried to grab the network driver by installing Windows, but it does not work in Windows too. so I came back to Linux.

"lspci | grep -i --color 'network | ethernet'" to search for network related information. However, no information comes out.

Also, when i look at the network manager, i can not get any wired LAN except ftp-proxy.

and boot When i checked the network in live mode using usb, I remember that the network related contents came out to the terminal.

The following information is displayed when the following command is entered. (in terminal, "inxi -Fz")

try this download the driver from here you want r8168-dkms.
you'll have to download on another machine and put it on usb stick or disc. what ever your machine will accept. right click on the file and select open with gedbi. install the driver, reboot see if network is working.

Thank you for answer.

After completing the installation and rebooting as shown below attached, the network still does not work.

It would be of help if you know exactly which realtek network card you have installed in that system.
It could be a bad card.
If it were me I'd try a usb external card see if that will work.

Thank you for your continued support.

The network card is an Intel® Dual Band Wireless-AC 8265 card from the MSI x399 gaming carbon pro motherboard.

During the initial Linux installation, the network worked without any driver installation, and it worked for a while.
(Therefore, I do not think bad network cards are personal...)

I deleted certain network related files while I was doing something, and there was a network problem after that.

So i am using an external usb to lan card, which works fine.

However, the network is unstable and i want to solve the problem.

Ok,
I was under the impression that the problem was with your Ethernet card.
Intell wireless cards are usually well supported in the kernel and need no additional drivers.
How ever they sometimes do need to be adjusted. Power save turned off etc.
next we need to know exactly which intel card it is then we can reinstall the correct driver.
and turn off the power save feature. Also you wireless router and be the culprit if there are a lot of other signals around your area.
you may need to change the channel being used.

Thank you for your continued support.

I was experiencing another issue, and I was late to resolve the issue.

As a result of executing your command, no results are output to the terminal.

Try booting into the Live ISO again and see if the network cards are found again

I'm sorry for late reply.

When i run booting with live a usb and run the "lspci | grep -i --color 'network|ethernet" command, i do not get any results.

And even when i run "inxi -Fz", the Network Card is still "failed to detect network card!" It comes out.
