nm-applet is a frontend for NetworkManager daemon and presents the
information from NM. NetworkManager uses HAL to get it's devices. It
looks for HAL UDIs which' "info.capability" property has string
"net.80211" (wifi) or "net.80203" (ethernet).

So if a device is missing from NM, first make sure HAL recognizes the
device as a network device.
