How do I prevent WiFi cycling between connected and disconnected?
My friend has a Acer Aspire 5733Z-4851 it keeps disconnecting and connecting to his wifi but his hard wire will run just fine. Any suggestions?

This is a known problem with atheros wi-fi and acer_wmi module.
Try black listing acer_wmi
by pressing Ctrl + Alt + T and pasting the below text in:
echo blacklist acer-wmi | sudo tee /etc/modprobe.d/blacklist-acer-wmi
You can then reboot or enter sudo rmmod acer-wmi
If this doesn't work, and you want to revert back,
remove /etc/modprobe.d/blacklist-acer-wmi (by clicking on your Home Folder, clicking on 'File System' under 'Computer' on the left pane, double-clicking on etc and then modprobe.d and deleting the file 'blacklist-acer-wmi')
