I have installed Plasma 5.18.4 on a new desktop with kernel 5.6.8. No issues with this kernel. How ever, I prefer to run LTS kernels, so I installed the linux-lts 5.4.36, and linux-lts-headers 5.4.36, but I get a “no internet connection” message when I boot from it. I have no problem with my other computer with the same linux-lts kernel, What am I missing here?
System:
Kernel: 5.6.8-arch1-1 x86_64 bits: 64 compiler: gcc v: 9.3.0
Desktop: KDE Plasma 5.18.4 Distro: EndeavourOS
I see you already have the lts-headers installed! Is it Broadcom wireless or something else?
—>
Updates from upstream:
linux 5.6.8.arch1-1 -> 5.6.10.arch1-1
linux-headers 5.6.8.arch1-1 -> 5.6.10.arch1-1
linux-lts 5.4.36-1 -> 5.4.38-1
linux-lts-headers 5.4.36-1 -> 5.4.38-1
kernel updates may solve this or give us:
lspci
dmesg | grep firmware
I installed the lts kernel and the lts headers on my Plasma setup to test it and didn’t have any issue with the wifi but i am using broadcom-wl-dkms as my wifi chip is broadcom. So it automatically rebuilds the kernel modules everytime you install a new kernel and wifi works. It does require the linux headers so if you install the lts kernel you have to install the linux-lts-headers also which you said you have. So that is why i ask which wifi you have?
I don’t have Wifi on that computer, and I don’t have access to that computer for another 8 hours to test the rest of it.
Well that’s a totally different issue then if it’s not connecting to hardwired connection.
One thing I forgot to mention was, I used the 2019.12.22 ISO, because the new one doesn’t work well with my AMD GPU, but everything is up-to-date, and I can connect fine with the 5.6.8 kernel!
Well there has to be an issue with the network component, So you have to boot into it to check it.

I updated to linux-lts 5.4.38, and still no connection, but I still can connect with kernel 5.6.10.

Your ethernet should be using the r8168… Can you show the output of the following
lspci -v
Edit: Could you check this booted in both kernels. I would like to know which module it’s using on the regular kernel and see what it shows booted into the lts kernel.
Here’s lspci -v for both kernels.

Kernel modules: r8169
So this is weird on the regular kernel doesn’t show as much as the lts kernel shows? But anyhow it does show on the lts kernel that it is using the r8169 and should be using the r8168 module.
So I’m not sure maybe you can check when booted on the regular kernel and see what it is using? You could try installing the r8168 and then see.
https://www.archlinux.org/packages/community/x86_64/r8168/
Edit: i also see one for the lts kernel but i worldn’t install it until you try and see if the regular module works and maybe works for both.
https://www.archlinux.org/packages/community/x86_64/r8168-lts/
r8168-dkms for linux-lts was missing. It started working right after I installed it! Thanks a lot ricklinux for the tip!
P.S. I just modified the grub time-out and then tried to update the grub, “sudo update-grub”, but it says command not found!
The grub command is sudo grub-mkconfig -o /boot/grub/grub.cfg
Edit: Hopefully that works for you? Also the r8168 i think has been added to the EndeaourOS ISO now for the next release. That particular chipset seems to pick the r8169 but it’s a problem for some.
Did you check it’s working on both kernels?
Yes, it works on both kernels.
r8168 was already installed originally.
I installed the r8168-lts, so both are installed, and working.
Grub update work for you?
Yes, that worked as well. This is quite different than Manjaro or Arch. I looked up Arch, and the command was sudo update-grub! In any case it worked.
Thanks again ricklinux!
This is the Arch command, Manjaro uses sudo update-grub. Glad it worked.
Edit: Those r8168 modules were just updated yesterday.
My solution to that:
alias update-grub='sudo grub-mkconfig -o /boot/grub/grub.cfg'
Of course, I got even lazier and just use rEFInd now… 
sudo rEFind -o /boot /rEFind/rEFind.conf
