I'm now getting my wired connection option not being available and also not shown with ifconfig. Also, my wi-fi connection hangs on trying to connect. I've tried various answers referred to below.

I followed the instructions and installed realtek-r8125-dkms package OK. On rebooting, I followed the instructed procedure (shown when installing the package) of Enrolling a MOK, creating a password and then entering it when requested on the reboot.

Yet more information:
I've now uninstalled the various dkms packages that following the procedures in the webpages (referred to previously) and the repos (in Software & Updates app) for them. These packages are: r8125-dkms, r8168-dkms & realtek-8125-dkms. The repos are for https://launchpad.net/~hardkernel/+archive/ubuntu/ppa and https://github.com/awesometic/realtek-r8125-dkms. Should I uninstall the dkms package?

I've also reset the keys for Secure Boot in the BIOS.

Rebooting after doing the above still results in WiFi hanging and no Wired fuctionality shown for establishing a network connection by clicking on the top right of the screen.

Would you please try OEM kernel?
#sudo apt install linux-image-oem-22.04c

Just tried the OEM kernel. I tapped the Shift key on rebooting. It gave 3 options on booting: Ubuntu, Advanced options for Ubuntu, UEFI Firmware Settings. I chose Ubuntu. It showed 6.01 and then came up with the standard login scree, On logging in (with my phone's Hotspot switched off; since these issues started I have it switched on as it's the only way I can get the computer connected to the internet), it now showed that Wired is Off whereas previously there was nothing about Wired. I've tried both Wired and Wi-Fi but both hang on trying to connect.

@John, before 22.04(5.19 kernel), have you ever get the Ethernet connection with 20.04 or other released version?

I bought the computer just under a year ago: it's an Asus (barebones) mini PN50-1 with a Ryzen 7 4700-U CPU. So it's always been using 22.04. I transferred the memory and SSD from my previous old computer. I think that I previously said that this computer was working on both Ethernet & Wi-Fi until about 2 weeks ago. Interestingly my wife's computer (an old Pentium laptop) is still Ok: it runs on 22.04 and had been upgraded Ok from 20.04 and previous LTS versions).

I don't recall what I did to make ethernet hang on attempting connection. It was a few weeks ago. As I previously detailed Wi-Fi also hung about 2 weeks ago. I only reported this on Launchpad a few days ago because I didn't know which package to specify when using ubuntu-bug. I have reported the problem on both Ask Ubuntu & Ubuntu Forums when it started to happen: there have been no replies.

I have not installed any new apps/packages for months except those packages installed by Software Updater & the attempted corrections previously detailed which I have reversed.

You should not need any DKMS packages nor an OEM kernel. The stock Ubuntu kernel supports your NIC natively. Remove the DKMS modules and reboot into the 5.19 kernel and post the dmesg output from that boot.

lsmod should list the r8169 module.

And:
$ modinfo r8169 | grep 8125
firmware: rtl_nic/rtl8125b-2.fw
firmware: rtl_nic/rtl8125a-3.fw
alias: pci:v000010ECd00008125sv*sd*bc*sc*i*

And the firmware should be there as well:
$ ls -la /lib/firmware/rtl_nic/rtl8125*
-rw-r--r-- 1 root root 3456 Apr 21 07:41 /lib/firmware/rtl_nic/rtl8125a-3.fw

dmesg.txt Edit (115.7 KiB, text/plain)

I checked that r8169 was in the OEM kernel. I used Synaptic to search for any dkms packages. Only one was dkms itself which I removed. I rebooted with 5.43 kernel and checked again for r8169: it was not present. How do I add it?

I forgot to mention that the firmware is present:
john@Desktop:~$ ls -la /lib/firmware/rtl_nic/rtl8125*
-rw-r--r-- 1 root root 3456 Apr 21 06:36 /lib/firmware/rtl_nic/rtl8125a-3.fw
-rw-r--r-- 1 root root 10128 Apr 21 06:36 /lib/firmware/rtl_nic/rtl8125b-1.fw
-rw-r--r-- 1 root root 3328 Apr 21 06:36 /lib/firmware/rtl_nic/rtl8125b-2.fw

When I said that I had removed dkms package, I meant purged.

BTW are the BIOS errors in dmesg relevant to the issue?

Are there any packages which I can reinstall (or even purge & install) which are used for connection to a router?

BTW I have a an old Pentium laptop also on Ubuntu 22.04 which works Ok still. The only thing that I can think of that is causing these issues is that sometimes my PC freezes (and I don't know why) which gives rise to some orphaned inodes on rebooting. I've even tried a TP-Link usb wifi dongle but that doesn't connect either on this Asus barebones PN50-1 computer but works OK on my old Pentium laptop.

Have you seen this web page?
https://github.com/unrloay2/ubuntu-network-driver-r8169

Any ideas how to download the specified files?

I have sent an email requesting help from unrloay2 (i.e. the author of this web page).

dmesg Edit (266.0 KiB, text/plain)

As I said before the Wired line has disappeared again. So I can't try to connect by Ethernet. dmesg output is attached.

@juergh
Tech Support Realtek told me to disable Secure Boot which I have done. I was then able to compile & install r8125, r8128 & r8128 modules obtained from Realtek website. 'lsmod | grep r81' showed all 3 modules. ifconfig showed the ethernet interface Ok (as enp3s0). However, ethernet still hung on connection. So I rebooted and did 'lsmod | grep 81' only showed r8125! 'modinfo r8169 | grep 8125' showed nothing. Help please!

@John, could you switch to another router for verification?

Using 'sudo smartctl -i -a /dev/sda', it shows for '202 Percent_Lifetime_Remain' the number 1. Does this mean that I should change my SSD ASAP?
PS I've been having lots of problems connecting to my router and even my Phone as a Hotspot.

Apologies to everyone trying to help. It turns out that the problem is the computer: a 4 month old Asus mini PN50-1. I suddenly remembered that the same thing had happened last August and that the supplier had given me a replacement after I returned the original.

Just got a new computer (MinisForums MC560) with Ryzen CPU. Ok for first few days. Now ethernet hangs. So turned Wired off & turned WiFi on. Ok for now. I daren't try Wired again in case WifI also stops working.

Interesting to compare the old computer & the new computer for ethernet using lspci -nn.
Old computer:

03:00.0 Network controller [0280]: Intel Corporation Wi-Fi 6 AX200 [8086:2723] (rev 1a)

02:00.0 Network controller [0280]: MEDIATEK Corp. Device [14c3:0608]

I found a web page re AMD Ryzen & Ubuntu to fix constant crashes:
https://www.servethehome.com/amd-ryzen-with-ubuntu-here-is-what-you-have-to-do-to-fix-constant-crashes/
But it dates back to 2017. So is it worth trying given that it refers to an old kernel version 4 and not the current version 5?
I've also found a reference to installing AMD GPU drivers at:
https://askubuntu.com/questions/1432449/how-to-install-amd-gpu-drivers-ubuntu-22-04-lts
Could this be relevant, especially as I don't do gaming?

A Realtek Ethernet Controller was on my old PC and it is on my new MinisForum MC560 PC and it is on my old Lenovo laptop. My old PC had an Intel AX200 wireless interface; my old Lenovo laptop has a Realtek wireless interface; my new PC has a MEDIATEK wireless interface. So there seems to be nothing in common between the problem PCs (old PC & new PC) which the Lenovo laptop has, except that the problem PCs are AMD Ryzen processors and the Lenovo laptop is a Pentium 1 processor!

My new PC doesn't even have WireGuard on it whereas my old PC had WireGuard on it, as I've decided to use a Raspberry Pi model 4 B for that.

Here is network details for new PC:
