I installed Manjaro KDE in a brand new MSI Modern 14 A10RB. I then installed the Nvidia corresponding driver, and optimus-manager to switch between my Intel integrated graphics card and my Nvidia GPU (Geforce MX250).

When I switch to the Nvidia GPU with optimus manager, I found out a very strange behaviour... I cannot connect to my home Wi-fi when I have my Nvidia GPU turned on.
When I go back to my Intel card though, the connection is as smooth as always (and the connection works perfectly for other devices in my home). I've tested this dozens of times just to make sure of what I'm saying.
To make things weirder... I tried to connect to my phone using a Wi-fi share point (so my phone was sharing the 4G internet connection to the laptop) and, to my surprise, the computer DOES get connected to the network.
Two more comments:
- The optimus manager 'hybrid' setting is not working, so whenever I have tried to switch to Nvidia, I've done it with 'nvidia' setting.
- The Wi-fi home connection actually worked once while the Nvidia GPU was activated. Don't know the explanation to this but it turned out to work that one particular time without me changing anything. In general, the computer finds the network and tries to connect to it but is not able to download or upload any data.
My questions are:
I don't know if the problem comes from my system, from optimus manager, from my GPU...? Is this usual? Is this an expected thing to happen when dealing with similar situations? How to fix it?
