Found solution. 
Problems can be solved
1) by hands: check if this helps then go to 2)
After "sudo pm-suspend"
  sudo rmmod ath_pci
  sudo modprobe ath_pci
  sudo /etc/init.d/NetworkManager restart
Network appears. If so, automate this
2) 
  sudo vim /etc/pm/config.d/modules:
>   SUSPEND_MODULES="ath_pci"
  sudo vim /usr/lib/pm-utils/sleep.d/10NetworkManager
>   case "$1" in
>       hibernate|suspend)
>          /etc/init.d/NetworkManager stop
>       ;;
>       thaw|resume)
>          /etc/init.d/NetworkManager start
>       ;;
>*) exit $NA
>       ;;
>   esac

Gotcha. 
Maybe Ubuntu ACPI Team could make this behaviour default? It looks like most of 
wireless modules should be unloaded before suspend.
