 Go to the Neighborhood view so you can watch things,
 then close the lid, wait for it to suspend, wait a bit more,
 then open the lid.

 It takes a long time to reconnect.

 This what I see:
 {{{
 The backlight comes on
 A second later, 3 mesh icons appear.
 A few seconds later, blink blink, and a few APs appear.
   (My AP is on channel 6.)
 After about 10 seconds, there is another blink blink,
   more APs appear (including mine),
   the WiFi LED turns on and it connects to my AP.
 }}}

 I've seen a couple of variations.

 Sometimes, it tries all 3 mesh channels.

 Sometimes, the WiFi LED doesn't turn on and it doesn't connect to my AP.
 If I poke my AP, the LED turns on and it connects.

 They may be related.  The case I just watched involved both of them.
