wifi turned off after standby

[flntobi]

My notebook is a Acer Travelmate 8372.

After returning from standby and sometimes when booting following behavior occurs:

The hardware wifi led is on. The network manager shows no connection (and there is no connection). After pressing the hardware wifi switch ones the wifi led turns off, nothing happens on th network manager. After pressing the hardware wifi switch a second time the wifi led turns on and the network manager connects to the wifi.
