Linux mint internet connection problem

Anything I should look into? I’ve tried everything to my knowledge. I’m beyond lost

So you don’t burn your brain completely, remove your boot drive and replace it and reinstall Linux Mint from scratch to get a go at it and work on the other disk later. I’m sure you will have better luck.

How to Configure Static IP in Linux Mint The Easy Way

You don’t actually expect someone to follow our advice do you :wink:

Ive watched the video 5 times. I don’t have a gateway. It’s a brand new ssd. I’ve uninstalled and reinstalled Linux mint 3 times.

Have you ever had any OS running on that computer with a working network?

Was it with the same Ethernet cable?
Can you use that Ethernet cable on a different computer that has a working network?

Or do you have a different Ethernet cable you can try?

Let’s eliminate the cable as a possible culprit.

Perhaps re-seat the cable, on both ends.

Do you have link lights at both ends?

Run ‘sudo dmsg|grep eth’ and provide output of it. You should see something similar to what I got here:

root@ubuntu:/home/jacek# dmesg | grep eth
[    2.470807] e1000e 0000:05:00.0 eth0: (PCI Express:2.5GT/s:Width x1) 11:22:33:44:55:10
[    2.486777] e1000e 0000:05:00.0 eth0: Intel(R) PRO/1000 Network Connection
[    2.494993] e1000e 0000:05:00.0 eth0: MAC: 3, PHY: 8, PBA No: FFFFFF-0FF
[    2.633895] e1000e 0000:06:00.0 eth1: (PCI Express:2.5GT/s:Width x1) 11:22:33:44:55:11
[    2.633898] e1000e 0000:06:00.0 eth1: Intel(R) PRO/1000 Network Connection
[    2.633986] e1000e 0000:06:00.0 eth1: MAC: 3, PHY: 8, PBA No: FFFFFF-0FF
[   14.898182] e1000e 0000:05:00.0 enp5s0: renamed from eth0
[   14.938074] e1000e 0000:06:00.0 enp6s0: renamed from eth1

In my case, Linux is aware of 2 Eth interfaces (both are working, only one is connected). You should see that output regardless whether you have a cable(s) plugged in or not.

When I run ‘ip address’, I get the following:

root@ubuntu:/home/jacek# ip address
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: enp5s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 11:22:33:44:55:10 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.106/24 brd 192.168.1.255 scope global dynamic noprefixroute enp5s0
       valid_lft 2700sec preferred_lft 2700sec
3: enp6s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000
    link/ether 11:22:33:44:55:11 brd ff:ff:ff:ff:ff:ff

As you can see, both are addresses are listed, but only the one with a cable attached (eth0 / enp5s0) got DHCP settings (the other (eth1 / enp6s0) has status DOWN).

In your case, you have only loopback address, what means that your setup is not recognizing the Eth chipsets (what I doubt, unless it is broken, what would be rather rare), or it was somehow not enabled during the setup (don’t know how Mint installer works).

If that is not addressed (missing etc0/1 in dmesg and renamed to something like enp5s0/6s0), there is no point banging on ping, etc. Also, trying to focus on loopback address is just wasting time (as several people pointed out, but you seems to be clinging to that).

Use the link about configuring network in Mint that @drhicom provided first (The Ultimate Guide to Linux Mint Network Configuration). If you are confused trying to follow, provide an output here. Otherwise, no one wants to guess what is in your head.

If you decide to reinstall it, you need to watch for something related to networking, where it says ‘localhost’ as that may be the place that screws your networking part. If you have a choice to specify DHCP, use that. (Again, it is not that your DHCP is not working, as this is depending on Eth working first.)

Have you ever had any other OS running on this machine where the network worked?
Also like Jacek, go into your system setup and make sure you have your ethernet card enabled.
.

Yes had this machine running windows 11 with this same set up

To make yourself from jumping out the window can you install a different version of linux mint ? Or install windows just to make sure your hardware still works, then switch the disks again.

I’ve tried Ubuntu also it’s not recognizing the eth cable. I’m gonna try another cable

As I said before, unless you provide answers / needed output, at least you lost me as I am not good at guessing.

Are you back from Radio Shack with the other lan cable??

I heard Ferrenghi was selling recently.

Small quantities should also appear at the market on Monday on DS9 (Klingon stand).

I also heard that 7 out of 9 obtain them from a certain type of champagne (unfortunately, it didn’t work from beer…)

So the issue can be resolved…

Whats the status with the new lan cable???

We do not even know the status of the old cable. @CrippleMikeD will not tells whether or not it has link lights.

What’s the latest status on this Lan connection?

Connection works in other computer fine.
