Title:
  unity-panel-service cause high cpu usage during wifi-connection

Status in Libindicator:
  Fix Committed
Status in The Ubuntu Power Consumption Project:
  Confirmed
Status in Unity:
  Won't Fix
Status in “unity” package in Ubuntu:
  Invalid

Bug description:
  During slow wifi-connection (f.e. lazy DHCP-server or low signal
  quality) unity-panel-service consume large part of cpu (up to 50%)
  while wifi-icon shows 'connecting' state.

  That problem disappear after connection established, but during travel
  there is many slow or broken wifi-networks with very long connection
  interval. This cause high cpu load for long time (sometimes minutes
  and even hours if we get in situation of constant disconnecting) and,
  of cause, quick battery discharge.

  Steps to reproduce:

  Set up wifi network with dynamic IP without active DHCP-server
  try to establish connection
  Checks the cpu usage of unity-panel-service
