1) acer aspire 5720z
2) Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)

Well, you posted pretty much everything but the output of lshw -c network, which would tell us whether your wireless interface is disabled or just not getting associated with any drivers. Although since no drivers appear to be loaded, that'd lead towards it being disabled.

Also, just to make sure, check that you haven't accidently disabled the wireless through a kill switch (laptops often have buttons for this), as that happens fairly often around here and causes behavior like this.
