For diagnostic purposes please follow the steps in https://help.ubuntu.com/community/WirelessTroubleshootingProcedure with the only deviation, that you should not create a new question document (with the link ending in +addquestion), but paste all output into this question document that has already been created https://answers.launchpad.net/ubuntu/+source/network-manager/+question/531498

The fix is usually to open terminal and enter
echo "blacklist acer-wmi" | sudo tee /etc/modprobe.d/acer-wmi.conf

Can you help with this problem?
