Good evening. I am a linux user, and I have a very annoying problem with Deepin 15.4. I decided to test this OS for the first time. I found it beautiful, practical and functional, but I have problems with the WiFi connection, that is extremely unstable and slow. I think it's because of driver issues. I've been trying to resolve for a week, but I could not. My PC had a Atheros QCA9565 / AR9565. I wonder if there is any way to proceed.
