To repair the cycle between connected and disconnected on an Acer Aspire 5733Z-4851, or other Acer Aspire laptop with Atheros Wifi, blacklist the acer_wmi module:

$ echo blacklist acer-wmi | sudo tee /etc/modprobe.d/blacklist-acer-wmi

Next, unload the acer-wmi module:

$ sudo rmmod acer-wmi

The first command adds the acer-wmi module to blacklist, so it is not loaded at the next reboot, and the second command unloads the module instantly.
