The same bug affects me (regression on upgrade from lucid to maverick), with the same driver (bcmwl-kernel-source).
I note for the reporter (assuming the problem is actually identical) that right-clicking on the wireless taskbar logo and ticking "Enable Wireless" successfully brings the device back up, and a short while afterwards a wireless connection is successfully made (and stays up). system: Lenovo Ideapad S12N lspci reports: 07:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01) lsmod reports: wl 1959533 0 lshw reports: *-network description: Wireless interface product: BCM4312 802.11b/g LP-PHY vendor: Broadcom Corporation physical id: 0 bus info: p...@0000:07:00.0 logical name: eth2 version: 01 serial: 00:26:82:32:35:77 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=wl0 driverversion=5.60.48.36 ip=192.168.1.5 latency=0 multicast=yes wireless=IEEE 802.11bg resources: irq:19 memory:c2200000-c2203fff On boot, lshw reports the same, except this entry starts " *-network DISABLED".
