"Wireless doesn't work after suspend with ath_pci driver



Wireless devices that use the ath_pci kernel driver, such as the
Atheros AR5212 wireless card, will be unable to connect to the network
after using suspend and resume. To work around this issue, users can
create a file /etc/pm/config.d/madwifi containing the single line:



SUSPEND_MODULES=ath_pci



This will cause the module to be unloaded before suspend and reloaded on resume. "
