internet / Network problems + printer not found

check also if rt816* in cat /etc/blacklist.conf

change to r8169
check if internet- network is ok

kernel 5.6 is EOL ( not more update )

you add after change in blacklist and reboot and internet ok

sudo pacman-mirrors --continent 
sudo pacman -Syyu
sudo pacman -S linux56-headers 

sudo mhwd-kernel -i linux54 
sudo pacman -S linux54-headers 
sudo mhwd-kernel -i linux419
sudo pacman -S linux419-headers 

reboot and press Esc , in Grub select detail > choose kernel5.4 or 4.19

each version kernel use proper firmware , status drivers r816* are not the same , check always for any kernel versions , keep always 2 versions or more

see for search about r8168 r8169

I'm realy feeling like an idiot.

Okey, internet seems to be fixed and the kernels are installed.
Many thanks.

But for some reason GRUB doesn't appear when I boot. Is there an other way?
(this starts to feel like a bad joke, I'm terribly sorry)

does your system boot into the desktop but you see no grub is that the issues? that's easy to fix

that is to say it is working as intended... no reason to see grub unless you boot more than one system or ahave installed more than one kernel and wish to chose between them.

Are you wishing to choose between them?

you need to edit grub

well that's the issue, I want to switch kernels do to mine being EOL

In this thread it says to hit esc or shift during boot to show grub so you can select the kernel you wish. Grub will show and you can select the kernel you want... and then you can go back to hiding the grub

or

GRUB_TIMEOUT_STYLE="hidden"

Replace in your /etc/default/grub file this line by GRUB_TIMEOUT_STYLE=menu using a normal editor like nano. Afterwards, sudo update-grub and reboot.

then run sudo update-grub and you will always and forever more see your grub on boot.

So, my system just died. I think I managed to gat a "bluescreen" in Linux XD

" Oh no! Somthing has gone wrong.
a problem has occurred and the system can't recover. Please contact a system admin"

turn it off for a few seconds and turn it back on take a deep breath

yeah, tried that, doesn't work.
Might need to reïnstall Manjaro , really hoped I wouldn't need to do this.

One thing we know, Manjaro is turning in to quite the adventure.
But I kinda don't want to go through al the crap of reïnstalling and tweaking everything.
Well thank God for coffee because I ain't gonna get anny sleep tonight.

what happens when you tried to boot manjaro? what did you see on your screen?

first black screen,
then the HP logo,
and finally the error message on a white background.

" Oh no! Somthing has gone wrong.
a problem has occurred and the system can't recover. Please contact a system admin"

tried to boot out of BIOS settings
( Esc, F9, Manjaro EFI)
same result

BAH!

Well you could follow the instructions to chroot into your system and see if you can even get in... or even boot from a livecd/dvd and see if you can access any of the partitions.. thats wherre i would start

Your kernel installation syntax posted earlier was incorrect, try:

sudo mhwd-kernel -i linux54 

So I did a complete clean reinstall of Manjaro. Was able to install my necessary programs and tweak them to my liking. This time I didn't need to manually partition my drive.

I also downloaded kernel 5.4.44-1 and 4.9.126.1 with Manjaro settings manager. (So far so good)
I noticed that my internet connection is still problematic and gets worse when I run on battery power. Is this connected to my kernel? (Currently running 5.6.16-1) If so, How do I get my Grub menu back to change it?

/etc/default/grub

GRUB_DEFAULT=saved
GRUB_TIMEOUT=10
GRUB_TIMEOUT_STYLE=hidden

And would I still need to get that "blacklist r8169" file?

echo -e "blacklist r8169" | sudo tee /etc/modprobe.d/r8169_blacklist.conf

so yeah change the style from hidden to menu and i think your grub should show be sure to run sudo update-grub afterwards so that it takes effect on next boot.

are you using r8168 ? if you want to use r8168 you need to blacklist 89

Oftentimes if your network connection behaves differently on battery power this could be an issue with tlp.

Read this regarding tlp:

If memory serves I don't have tlp installed or activated.
tried it anyway. didn't work. Still network-problems when on battery power.

To be fair I don't know what this r8168 / r8189 thing is, so could you tell me what it does or why I might need to change from 68 to 89?
I got the tip from stephane that this might help fix my network problem.
And I'm a bit held back from installing things that I don't know what they do, do to my system having crashed. And I really don't what to go over everything again, it's cumbersome and it takes a lot of time I can't afford to lose right now.

You'd want to peruse the entire thread linked... it's the driver for your internet. one is baked into the kernel and the other is not... if the one baked into the kernel isnt working properly then you can try the other.
