Hi, Since I updated my laptop to 4.11-rc* the wireless is fairly instable (I think it was already less stable with 4.10 than with 4.8, but no clear data) For example it locked up (no more wireless) with a warn on while connecting and actually needed a reboot to recover (reloading modules was not enough) Any fixes/workarounds?
