Internet Issues after installing ZorinOS Core 17.3

[OnorevoleMarco]

Hi everyone,

I wanted to try ZorinOS Core by installing it. Everything went fine with the installation but when i rebooted to the installed OS i have internet issues and after a while the OS doesn't see my wired cable anymore.

I have a r8625 and this is the configuration that it shows

The configuration is wrong since my router is on 192.168.178.1 so the devices on my local network works on 192.168.178.x i tried putting the manual configuration but it still doesn't work

I am using USB tethering from my phone to write this so that i can do whatever it needs for this issue to be fixed.

Thank you everyone in advance for your help!

EDIT: I want to add that the first screenshot is with DHCP on but it will show the sam thing even after manually changing the network configuration

I must assume that r8625 is a typo and the card is r8125.
Is the driver loaded?

lspci -nnk | grep -A3 -i ethernet

If it is not, or it shows r8169 in use, you must install the r8125 driver.
Using your mobile hotspot to connect, in terminal run

sudo apt update && sudo apt install r8125-dkms

[OnorevoleMarco]

Yeah sorry i meant r8125

@Aravisian

s the driver loaded?

lspci -nnk | grep -A3 -i ethernet

I forgot to say that also wifi and bluetooth aren't working for some reason

[Aravisian]

What is your terminal output for

sudo lshw -C network

You have the current and correct drivers, so what I would like to check is if you are using Wifi 6 or Wifi 7 NIC's.
Are you using a VPN?

Hi, i saw one of your posts where you said that secure boot wasn't needed on Linux so i tried reinstalling ZorinOS with Secure Boot disabled and the ethernet connection actually works. So i guess it was just secure boot.

So now i'm actually connected even if i don't have secure boot at least i can connect to the Internet. I still don't have WiFi and Bluetooth tho

Let's try

sudo modprobe -r iwlwifi

sudo modprobe iwlwifi

[OnorevoleMarco]

Nothing, still no wifi or bluetooth

Please check if fast boot in your BIOS is disabled and also fast startup in Windows if you use Dualboot. They can prevent wlan drivers from being loaded correctly.
If you use Windows try to update the Realtek r8125 driver in Windows to version 10.76 or higher with the driverdownload from Realtek. I read the default version of this driver used in Windows can cause NIC problems in Linux.

[Ponce-De-Leon]

Did You take a Look in the ''Additional Drivers'' Tab in Software & Updates if there is maybe a Driver offered for Your Wifi/Bluetooth?

And is the System running in Wayland or X11? You can check that in Settings>About. when there stands Wayland, I would suggest to try switch to X11/Xorg and see if it works then.

To switch, go to the Login Screen (not the Lock Screen). simply reboot for that. On the Login Screen, click on Your Profile so that the Password Field appears. After it is appeared, You should see a Gear Icon in the bottom right Corner. Click on it and choose the Option ''Zorin Desktop on Xorg'' and then log in.

I'm Dualbooting and tried disabling fast startup both on WIndows and on BIOS, and installed the 10.76 r8125 drivers on windows and did a fully shutdown and then booting on ZorinOS but still no wifi or bluetooth

I am on x11

What a pity! I had hoped it might help. Before you try to install the WLAN driver from Realtek as tar.gz, you could try it with a newer kernel to look if that helps. If not, you can easily go back at grub menu to the normal 6.8 kernel.

Recommended is the installation via mainline tool. You could choose kernel 6.14 or if you have the newest hardware kernel 6.15.

So you ran into an issue that's hardware related but your hardware is newer and the issue could possibly be fixed after installing newer drivers and so you need to update your kernel? Well, here's how easy it is to update your Kernel in ZorinOS.: TuxInvader Kernel For Zorin OS 16 users (Focal Fossa): Open up terminal Type and enter these 3 commands one by one: sudo add-apt-repository ppa:tuxinvader/lts-mainline sudo apt update sudo apt install linux-generic-X.XX Notice that I have writte…

Tried 6.12,6.14 and 6.15 but nothing. Also tried installing the official tar.gz from Realtek.

Also tried installing the official tar.gz from Realtek.

And did that help? You did take it from here, yes?

Realtek

And there this one?

[Aravisian]

@Forpli

Realtek r8125

From what I understand, the RealTek (Ethernet) is working, it is the Wifi and Bluetooth (Radio) that is not.

Subsystem: Intel Corporation Device [8086:0094]
Kernel modules: iwlwifi

@OnorevoleMarco, can you please try

sudo apt update && sudo apt install linux-firmware

Then please relay the terminal output for:

dmesg | grep iwlwifi

While waiting after running the above- you can cycle a full shutdown and boot up to test if wifi is now working...

[OnorevoleMarco]

I managed to solve it when i turned off my PC for 1 hour and now i'm back and all the devices works for some reason. Thank you all for your help
