Public bug reported:
Since upgrading to 12.04, my wireless connection has been failing
randomly. It works fine for an indeterminate time after connecting to my
router, and then randomly all traffic ceases, and I become unable to
load any websites, download anything, or even ping my router. The
wireless connection may work fine for as long as a few hours or as short
as a few minutes before this happens. Every time it happens, I check
all the logs, but there is no log entry corresponding to the loss of
connection. It happens regardless of whether or not the laptop is
plugged in. My wireless card is identified in lspci as:
0c:00.0 Network controller: Broadcom Corporation BCM4321 802.11a/b/g/n
(rev 03)
uname -a: Linux aeolus 3.2.0-24-generic #37-Ubuntu SMP Wed Apr 25
08:43:22 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
Please let me know what other information I can provide, and I will
happily provide it.
