You can also try:

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

after my previous post.

For some funny unknown reason Kernel 4.12 is not displayed here

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

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

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 Smile

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 Wink

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..
May want to check NICs are not disabled in Network Manager
Clicking the wireless/network icon ensuring checks by Enable Wi-Fi and Enable Networking

Re: No network after installing kernel - trinidad - 02-23-2018

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.

Found it, pressed it, nothing happened

Nothing is there in my network options
I see four options
  1. Network
  2. Network Connections (with folder Icon)
  3. Network Connections ( with 2 screens Icon)
  4. Network Share Settings
Quote:Clicking the wireless/network icon
This Icon disappeared after the installation of Kernel 4.12 and hasn't return after de-instalation

Re: No network after installing kernel - CSNLinux - 02-26-2018

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!?

Re: No network after installing kernel - trinidad - 02-26-2018

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

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