  Broadcom WiFi left in inconsistent state after suspend, shutdown in

Status in “linux” package in Ubuntu:

Bug description:
  This is a Lenovo IdeaPad S206.
  Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

  Current behavior is: 
  WiFi will operate pretty well -- quite stable.  
  Then I suspend the system, move to another WiFi hotspot, and wake the system up.
  It will see the other hotspot, but keep prompting me for a password which it already has.
  This happens about half the time... In fact, maybe exactly half the time I wake the system up.
  I have also seen it happen when the system is shut down and re-started.
  It will never again authenticate once it gets into this state.

  Hardware reset: shut system down, hold power button while the splash-screen is displayed, until the machine shuts down (about 5 sec.)
  Then re-start.  Voilà, WiFi authenticates and works fine, until the problem occurs again.

  WiFi on this machine has always been problematic.  It did not function after a clean install of the system.
  (For all I know, it was already the inconsistent state problem.)
  I had to fiddle around a great deal to get it working even this well... 

  The same system running off a stick with Ubuntu 13.04 Beta is *unusably* flaky regarding WiFi.

  $ lsmod |grep wl
  wl                   2906499  0 
  cfg80211              175574  1 wl
  lib80211               14041  2 lib80211_crypt_tkip,wl

  How can we debug this?
  (How to look directly at the WiFi hardware state?)
