** Description changed: If I boot up my laptop with the wireless disabled, then enable it once the machine has booted, I can not see any APs or use the wireless unless I restart. Even if the wireless is enabled, it is a gamble as to whether not wireless will work. It seems to be very random as to whether or not it will decide to connect or not. At times it will see all available APs and try and connect, but then always popup with the password dialog box for the AP and regardless of what password you enter (correct or incorrect), it will never connect. I have tried the instructions from this bug report [ https://bugs.launchpad.net/ubuntu/precise/+source/bcmwl/+bug/1002703 ] but still having the same issues. ( sudo apt-get remove bcmwl-kernel-source sudo apt-get purge bcmwl-kernel-source - sudo apt-get install linux-firmware-nonfree ) + sudo apt-get install linux-firmware-nonfree ) My machine is a Dell Vostro 1540 with a Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01) + + I should add that this laptop was upgraded from 11.10 where I never had + any issues with the wireless, it just worked from first install. Here seems to be the relevant issue form dmesg: [ 86.282492] ------------[ cut here ]------------ [ 86.282521] WARNING: at /build/buildd/linux-3.2.0/net/mac80211/rx.c:2985 ieee80211_rx+0x12b/0x180 [mac80211]() [ 86.282524] Hardware name: Vostro 1540 [ 86.282526] Modules linked in: pci_stub vboxpci(O) vboxnetadp(O) vboxnetflt(O) joydev vboxdrv(O) dm_crypt parport_pc rfcomm bnep ppdev binfmt_misc snd_hda_codec_hdmi snd_hda_codec_idt snd_hda_intel snd_hda_codec bcma snd_hwdep snd_pcm psmouse snd_seq_midi snd_rawmidi snd_seq_midi_event arc4 snd_seq snd_timer snd_seq_device brcmsmac mac80211 brcmutil cfg80211 mei(C) dell_wmi dell_laptop dcdbas serio_raw lp uvcvideo snd videodev crc8 cordic btusb bluetooth mac_hid sparse_keymap intel_ips soundcore snd_page_alloc parport ums_realtek uas usb_storage wmi i915 r8169 drm_kms_helper drm i2c_algo_bit video [ 86.282580] Pid: 0, comm: swapper/3 Tainted: G WC O 3.2.0-26-generic-pae #41-Ubuntu [ 86.282583] Call Trace: [ 86.282589] [<c158f6ca>] ? printk+0x2d/0x2f [ 86.282596] [<c105a682>] warn_slowpath_common+0x72/0xa0 [ 86.282618] [<f918c9eb>] ? ieee80211_rx+0x12b/0x180 [mac80211] [ 86.282630] [<f918c9eb>] ? ieee80211_rx+0x12b/0x180 [mac80211] [ 86.282632] [<c10612c0>] ? local_bh_enable_ip+0x90/0x90 [ 86.282635] [<c105a6d2>] warn_slowpath_null+0x22/0x30 [ 86.282646] [<f918c9eb>] ieee80211_rx+0x12b/0x180 [mac80211] [ 86.282648] [<c149f85e>] ? skb_dequeue+0x4e/0x70 [ 86.282657] [<f916fbf0>] ieee80211_tasklet_handler+0xb0/0x160 [mac80211] [ 86.282663] [<f92b4fd3>] ? brcms_intrson+0x33/0x40 [brcmsmac] [ 86.282665] [<c15a5376>] ? _raw_spin_unlock_bh+0x16/0x20 [ 86.282667] [<c10612c0>] ? local_bh_enable_ip+0x90/0x90 [ 86.282669] [<c10612c0>] ? local_bh_enable_ip+0x90/0x90 [ 86.282671] [<c1060de3>] tasklet_action+0x63/0x110 [ 86.282673] [<c10612c0>] ? local_bh_enable_ip+0x90/0x90 [ 86.282675] [<c1061341>] __do_softirq+0x81/0x1a0 [ 86.282677] [<c10612c0>] ? local_bh_enable_ip+0x90/0x90 [ 86.282678] <IRQ> [<c1061686>] ? irq_exit+0x76/0xa0 [ 86.282682] [<c15acddb>] ? do_IRQ+0x4b/0xc0 [ 86.282684] [<c15acc30>] ? common_interrupt+0x30/0x38 [ 86.282687] [<c105007b>] ? print_cpu+0x25b/0x910 [ 86.282689] [<c1303aea>] ? intel_idle+0xda/0x140 [ 86.282691] [<c147bc1d>] ? cpuidle_idle_call+0xad/0x250 [ 86.282694] [<c10102ec>] ? cpu_idle+0x9c/0xe0 [ 86.282696] [<c158886c>] ? start_secondary+0xe8/0xed [ 86.282698] ---[ end trace 218659c5e77c767b ]--- ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: linux-image-3.2.0-26-generic-pae 3.2.0-26.41 ProcVersionSignature: Ubuntu 3.2.0-26.41-generic-pae 3.2.19 Uname: Linux 3.2.0-26-generic-pae i686 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
