I've been having issues the last days where the internet connection was very bad when using my old Dell laptop and watching videos in brave-browser - in the Zorin 18 Core live session and on the bare metal install of Zorin 17 Lite.
Because I thought I have an Intel wifi card (I'm no longer sure and look later if that is right), I tried to run the
sudo modprobe -r iwlwifi
command to remove the kernel module and then to reload it, but that crashed in both cases the computer. The screen showed only a black background with some stripes and was unresponsible.
What am I doing wrong? Do I need to stop NetworkManager first? Or close the brave-browser?
I used that command a while back, and it worked fine then. Unfortunately, I don't remember if I did anything differently back then.
It should not behave that way, I'm confused. Is the command only for specific kernels? In the live session I was running 6.17 kernel, on bare-metal liquorix.
I tested the command on my newer Dell laptop, and there it worked fine without stopping the NetworkManager before or closing brave-browser. The video stops and is not shown during the process, but the computer doesn't crash. And afterwards, the video appears again.
