Comment (by aleksabl-gmail):
I can also confirm this bug, along with other Ubuntu users (https
://launchpad.net/ubuntu/+bug/66481 and http
://ubuntuforums.org/showthread.php?t=305491).
I'm using a SMC EZ Connect Wireless G PCI 108 Mbps card which has the
AR5212 chip.
{{{

The PC is located 3 meters away from the AP. I'm having problems with loss
of connectivity and low speeds.
If anyone knows a workaround for this bug, please let me know.
