Netgear WPN511 Fails After Sleep

I purchased a Netgear WPN511 PC Card (PCMCIA) for my laptop. This card is based on the Atheros chipset and works very well under Linux, except that the drivers fail to work after waking up from sleep.

To workaround the problem, create a file called atheros in /etc/pm/config.d/ with the following line.

SUSPEND_MODULES=ath_pci
