No Ethernet/network

Support and Help

Hello!
I tried installing Ubuntu Studio, but I experienced the same issue both times after installation.

Ubuntu Studio doesn’t see my Internet connection. I have a wired connection. I have no idea what to do.

(The topic is so short because previously I got “access denied” because my topic was deemed similar to other topics, even though the alternatives that come up have absolutely nothing to do with it.)

Welcome! Some more details would certainly help, including what version of Ubuntu Studio you’re installing, and what type of computer. Like, make and model. if you know what type of Ethernet or WiFi chipset, what you’re connecting to, that will be helpful too. Did the network connection ever work? Is this a new computer or one you’ve used with Linux before?

However, here’s some generic network debugging steps you can do in a terminal on the install:

  1. First, make sure the network hardware is detected:

    ip link show

    This will show all network interfaces. Look for something like eth0 or enp0s3 - these are common names for wired connections.

  2. If you don’t see any network interfaces except lo (loopback), check if the network driver is loaded:

    lspci | grep -i ethernet

    This shows your network card. Make note of what it says - this is useful information if we need to find the right driver.

  3. Check if NetworkManager is running:

    systemctl status NetworkManager

    Look for “active (running)” in green. If it’s not running, try:

    sudo systemctl start NetworkManager

  4. If NetworkManager is running, try:

    nmcli device status

    This shows the status of all network devices. Your wired connection should be listed here.

  5. To try to connect manually:

    sudo dhclient eth0

    (Replace eth0 with whatever name you saw in step 1)

If none of these steps work, please share the output of these commands - particularly the lspci command, as this will tell us what network hardware you have.

Also, some quick physical checks:

  • Check if the network cable is firmly plugged in at both ends
  • Look for any lights on the network port - are they on/blinking?
  • Try a different network cable if you have one
  • Try a different network port on your router if possible

Feel free to add some more details in a reply, and let us know if you tried the steps above and if they help.

I wanted to write more details, but couldn’t post the question with those…

I built the computer myself almost ten years ago.
The motherboard is an ASUS H87M-E.

Ethernet should be Realtek PCIe GBE Family Controller. I have no WiFi on this computer.

The network connection works, it’s my Win computer (but I don’t want to have Win anymore, because the computer can’t be upgraded to Win11, but it has very high specs, except for the graphics card - I bought an affordable one, I didn’t want to waste money on a very expensive one, because gaming isn’t my main focus).

I’ve been testing different Linux distros on two separate disks. Linux Mint and Ubuntu GamePack were okay, I had an internet connection and sound through my external audio interface on both of those, but on Ubuntu Studio I don’t even have sound, there is no sound hardware found at all.

I’ll look at those debugging suggestions, thanks!

I’m installing Ubuntu Studio 24.10.

Did you try your ethernet with Ubuntu 24.04.
I mention this because there could be an alternative approach:-

  • Install Ubuntu 24.04
  • Add ubuntustudio-installer

24.04 seems to have worked. I have Internet connection and sound. Thanks for the help! But I’ll also keep the debugging terminal tips from popey, those might come in handy in the future!

If (or when) you add the packages from ubuntustudio-installer, there is a choice of kernel and kernel settings.
It may be the different kernel that interferes with your ethernet?
Just something to consider.
