I've switched back to Mint after struggling with the wifi on Manjaro. After a few updates it became unusable. I didn't have the energy to figure out what was wrong. Pity though, Manjaro was great otherwise. I'll miss Pacman.
I've an issue with Mint though. I connect an external monitor and keep the lid of my laptop closed most of the time. Now when I do that on mint, I'm not able to connect to any wifi networks nearby. So I've to keep the lid open to stay online. It's weird, since I can see the available networks, but not connect to it. Annoying, but not a show stopper.
