It's happening on my work's PC and it's making me mad. Just wanted to start from zero this new year with Linux.
WiFi runs good for X time; may be 5 minutes or 10 hours. But at a point, it disconnects and I have to restart NetworkManager until it works again (sometimes one time, sometimes 50).
I have a TP-Link TL wn722n v1
Here goes the dmesg information when I can't connect:

... and it keeps going and going. This time, I disconected and reconnected the WiFi adapter and it worked properly on the first try. dmesg said:

I'm waiting for it to fail again. If anyone can give me a hand I'll be grateful! Thank you all.
