And sometimes I find wifi and bluetooth missing after sleep. I cannot exactly define preconditions, but it seems there are following steps to reproduce the issue 1. Connect something via bluetooth (I use bluetooth headset) 2. Send laptop to sleep 3. Wake it and find wifi and bluetooth missing. I have to mention that I have also been experienced bluetooth only missing, but it somehow transformed to the issue with both wireless devices.
