Next time this happens, and NM doesn't find it, run (as root):

iwlist wlan0 scan

(replace wlan0 with your wifi card's interface name, which you can find
by running 'iwconfig').

Does your AP show up, even if it's SSID Is blank?  Look for the MAC
address matching your AP.  Let me know!

NM depends on the hidden AP's MAC address showing up in the scan (which
it will, if the driver for your card doesn't suck) so that it can match
up saved connection details with your AP.
