Get it working again and look at the output of iwconfig.  Check the
"Link Quality", "Signal level" and "Noise level" values.  It could be
that you're on the fringe of your signal area and lost the connection.

Here's output for a solid system:

wlan0     IEEE 802.11g  ESSID:"ohnoyoudont"  
          Mode:Managed  Frequency:2.442 GHz  Access Point:
          Bit Rate=54 Mb/s   Tx-Power=27 dBm   
          Retry min limit:7   RTS thr:off   Fragment thr=2346 B   
          Encryption key:xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xx
          Link Quality=100/100  Signal level=-47 dBm  Noise level=-93
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

That's on a mac80211/iwl4965-based Intel wireless NIC on F7.
