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 ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: unity-services 5.12-0ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-24.37-generic 3.2.14 Uname: Linux 3.2.0-24-generic i686 .tmp.unity.support.test.0: ApportVersion: 2.0.1-0ubuntu7 Architecture: i386 CompizPlugins: [core,bailer,composite,opengl,compiztoolbox,decor,imgpng,expo,scale,workarounds,move,place,gnomecompat,mousepoll,vpswitch,snap,wall,resize,grid,staticswitcher,unityshell] CompositorRunning: compiz Date: Thu May 17 18:33:55 2012 DistUpgraded: Fresh install DistroCodename: quantal DistroVariant: ubuntu GraphicsCard: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Lenovo Device [17aa:21da] Lsusb: Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 8087:0024 Intel Corp.
