While trying to establish a connection in "auto" i.e. dhcp while here is no dhcp server the cpu usage for plasmashell maxes out 1 core. I don't know if the animation is responsible or other process. How can I debug this? Thanks.
Which plasmashell version? Also, are you really using 'knemo' or Plasma's network monitor widget?
plasmashell 5.9.4 Its the plasmashell process that occupies cpu resources so I guess it is Plasma's network monitor widget
