Hi Vagner,

thanks for your quick reply! I tried out your proposal and together with power 
management switched off (iwconfig wlp2s0 power off) the chipset works like a 
charm! 

A big thank you to you and the professor from India! You made my day :)

I just keep wondering now whether the disabled power management
will increase the battery drain but maybe the firmware does handle
those things by itself...

So have a nice day and cheers,
Tobias
