Comment(by gnu):

 Also tried this in 8.2-659 with Q2E15.  It, too, lost the AP association
 after resuming from a power-button press.  However, it eventually did
 automatically gain it back.

 When I tried shutting the lid, the first time, it didn't suspend.  I could
 see the LCD backlight through the USB port on the right side.  I opened
 and shut it again, and it suspended, and turned off the WiFi.  I put the
 mouse hovering over the Frame icon for the wireless.  It came up as Mesh
 1, then Mesh 11, then Mesh 6, then finally switched to AP ToadHall2 and
 connected to that.  Why it takes a whole minute to uselessly dribble
 through the mesh I don't know, but I'm happy that it works as well as it
 does!

 I tried again and timed it, using the power button and the Frame status.
 It succeeded in re-associating to the access point 94 seconds after
 resuming.  (Browse crashed shortly thereafter, taking me to the Network
 screen and removing Browse from the Frame.  dmesg shows it was not an out-
 of-memory.  I don't know if the Browse crash is related to the suspend
 testing.  I was looking at the OLPC wiki "Community News" for August 28
 page.)
