16:10 update, laptop looses network when going to sleep mode

[robert rottermann]

Hi there,

I update my del xp15 to ubuntu 16.10.

Now when I close the lid and it goes to sleep mode and the wakes up 
again it looses the network connection.

To reattach the network, I have to restart the network-manager.

 From the messages during the wakening process i get the impression, 
that the network is running in the beginning of it, but then later the 
connection is lost.


Any idea how to fix this?


thanks

robert
