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.

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.
