Wired Internet not working

Hardware Support

I upgraded to Zorin 16 Beta. My wifi works but it slow and my wired internet does not work at all. I have tested on another computer and there is no issue with connection on other computers.

It looks like you have a relatively new network card. Linux in general works best with a machine on a bit older side because of the time needed volunteers working on the new hardware.

A search "RTL8125 2.5GbE Controller Ubuntu 20.04" comes up with:

Not sure if any of that will help you.

I forgot to mention.
To solve the internet connection, you got be able to connect to the internet :roll_eyes:
To solve this dilemma, I have a USB WiFi dongle which always works in Linux. They are quite inexpensive, around 5 to 6 Euro each. Look for the chipset either RT5370 or 8188cus (both are from Realtek).

Er... Catch 22.

Well, almost.
But now we all have a mobile phone with data link - that would at least let you order a USB dongle at Amazon :grin:

Rosa, as I recall, you had this same trouble on Zorin 15.3, right?

I had a slightly different issue with the wifi, but that solution did not work on 16. I never did get the wired connection working on 15.3 but because wifi was working fine I just left it. I'm going to try running through some of the suggestions above and will mark which one works. Thanks everyone.

The solution listed in one of these worked to get the wired connection finally working. I have copied the solution and pasted it below.

" I downloaded the driver from the realtek website to get the 2.5G Ethernet LINUX driver r8125 for kernel up to 5.6

From a Terminal window run:

sudo apt install r8168-dkms (this package was needed in order to run the r8125-90004.01 diver script with no errors)

cd /home/username/Downloads

cd r8125-90004.01

sudo chmod +x autorun.sh

sudo ./autorun.sh

sudo reboot

Please keep in mind that whenever you Upgrade the kernel, due to dkms, you will need to repeat this procedure to reinstall your driver. So keep a copy of this in a .txt file your Documents for easy access, too.

Or you could do the same thing I did recently.

I wrote several tutorials for this forum regarding installation and configuration of Zorin. Not only those tutorials help others, I know exactly where to look for next time I need those informations myself :wink:
