Created attachment 121150 [details] Wifi trying to connect uses a stable 49% CPU SUMMARY The process plasmashell will will take up to 50% of the CPU when the Wifi network won't connect. It takes either 25% or 50% and it is a stable utilization as if the process went out of control. STEPS TO REPRODUCE The bug is always reproducible: when the Wifi is activate it will start consuming CPU, as soon as I deactivate it, the utilization will go down to 0-2%. 1. Activate Wifi. 1. Find a Wifi connection that won't connect: a connection that will successfully authenticate the user but will not go beyond "applying networks address" phase. 2. Try to connect to that network without any other alternative available. If there are no alternatives the process will go timeout and keep trying to connect to the same network. OBSERVED RESULT Watch CPU utilization jump up and fans start spinning like crazy.
