If the device isn't listed in ifconfig the the kernel cannot see it, and thus NetworkManager can't see it. It seems like there is either a hardware problem with your wifi device, or the kernel has been updated and no longer recognizes the wifi device. What is the output of 'lsusb' and 'lspci' when those commands are run in a terminal on your machine?
