Okay, So when I start LL in repair mode / save mode (what's it called)
I suddenly have a working network connection. When rebooting and start in normal mode....gone!!!

Is this to be solved or better start all over from scratch?

Should be powersave not powersafe.
Changed it, entered the command but nothing visual happened.

Maybe you could copy commands to a USB stick with notepad (save as a text file) then copy and paste from the USB text file to the LL terminal.
:-\ Why didn't I think of that.

Now that you're on the 4.4.x-x kernel series run the commands Jerry suggested.
   
1) sudo rfkill unblock all

2) sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/g' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

TC
Oké that was a lot of typing.
Result
Code: [Select]
sed: can't read /etc/NetworkManager/conf.d/default-wifi-powersafe-on.conf:
No such file or directory

Are we all stuck on the same page here?
Can imagine!
I thought about a clean install of LL on my laptop but I remembered that I had WIFI issues from day one.

Hmmm...what to do!?

reboot choosing advanced options selecting an earlier kernel (Choose 4.4.0-112)
Done!

Once 4.12 is removed you can reboot and typical LL option will boot back to 4.4.0-112
Done!

Nothing is there in my network options
I see four options
  • Network
  • Network Connections (with folder Icon)
  • Network Connections ( with 2 screens Icon)
  • Network Share Settings

Clicking the wireless/network icon
This Icon disappeared after the installation of Kernel 4.12 and hasn't return after de-instalation

Yep. You have to select the next oldest kernel from Advanced Options in the grub menu and boot that one first like Jerry said. Once you're on that 4.4.x-x you can delete 4.12 from Lite Tweaks. Hold down the shift key when you turn on the computer and you should get the grub menu where the Advanced Options are. Arrow key to scroll down to it. Enter to open it. Enter to boot the selected kernel. Most of this is in help manual.

So yes you're booted to 4.12, reboot choosing advanced options selecting an earlier kernel (Choose 4.4.0-112)
Once booted to 4.4.0-112 will be removable in Lite Tweaks.. 4.12 isn't showing in tweaks now cause your in it :)

Once 4.12 is removed you can reboot and typical LL option will boot back to 4.4.0-112

Now you should be back - but wanted to get you past your last post - Not to step on TC or others toes, maybe I saved them from typing the same ;)

The newer kernel may not work with your hardware as you're seeing, some of my older stuff gets flaky if I try higher than 4.4..


If still in 4.12
But the hard block as mentioned could be a keystroke (mine is fn+F2) look for the tower with waves.. Or post your laptop model and we can confirm..

Clicking the wireless/network icon ensuring checks by Enable Wi-Fi and Enable Networking

You're probably running on it. What does uname -srv show?

There is no need for the 4.12 kernel either, so remove that before you do anything else first via Lite Tweaks.

For some funny unknown reason Kernel 4.12 is not displayed here



Or is it here, but not named the same way?

You can also try:

Code: [Select]
sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/g' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
after my previous post.

My god! What are you on the internet with now? You download the .deb using whatever computer you have working, you put it on a USB stick or external drive and transfer it to the dead machine, once
You don't need a network connection to do that, that's why I suggested it!


'My god' and such responses are not helpful and don't instill confidence in people.

@CSNLinux try the following:

Code: [Select]
sudo rfkill unblock all
You are hardware blocked, so it's either BIOS or a key combo as others have stated. You can also try resetting your BIOS to defaults. There is no need for the 4.12 kernel either, so remove that before you do anything else first via Lite Tweaks. You need to press Shift key when you boot up to get the Grub menu, select Advanced options and choose an earlier kernel. Then you can remove 4.12

... he downloaded the original kernel and headers version as a .deb file...

Hmm, I never tried downloading without a Network Connection. ???

Thanx anyway :D

My god! What are you on the internet with now? You download the .deb using whatever computer you have working, you put it on a USB stick or external drive and transfer it to the dead machine, once it's on there double click it and install it just like you would on Windows.
