Thanks for taking the time to report this bug and helping to make Ubuntu
better. We appreciate the difficulties you are facing, but this appears
to be a "regular" (non-security) bug.  I have unmarked it as a security
issue since this bug does not show evidence of allowing attackers to
cross privilege boundaries nor directly cause loss of data/privacy.
Please feel free to report any other bugs you may find.

Title:
  wireless treats driver failure as network security refusal

Status in network-manager package in Ubuntu:
  New

Bug description:
  I've a Lenovo 585 with Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter - this combination leads to frequent driver failures (sudden component shutdowns) with sound and network hardware being the most likely to temporarily abort.
  (this isn't the first laptop I've seen this problem on either)

  Every time the hardware crashes and resets, network-manager treats
  this as a security abort and asks (erroneously) for network
  credentials.

  a: this disrupts all running program and puts up a modal dialogue
  b: this is unnecessary, because above.
  c: this is a security risk because it will try (under normal circumstances) to hop networks until it finds an open one, and this can put the unit into a secure vulnerable state.

  I'm happy to help provide more info - this bug hits me anywhere up to
  several times an hour.

  recommend : this is a security risk / serious / blocking (fix asap)
  bug.
