After update to latest Jaunty kernel wifi (BCM4312) is not working any more

[Oliver Bedford]

After automatic update to
ojo@hermes:~$ apt-cache policy linux-image-2.6.28-13-generic
linux-image-2.6.28-13-generic:
  Installiert: 2.6.28-13.45
  Kandidat: 2.6.28-13.45
  Versions-Tabelle:

my wireless card is not working any more.

Machine is a Dell Vostro 1310 with
06:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)
        Subsystem: Dell Device 000b
        Flags: bus master, fast devsel, latency 0, IRQ 19
        Memory at f4000000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: <access denied>
        Kernel driver in use: wl
        Kernel modules: wl

It looks like the wl driver is not loaded (and therefore I don't have Internet access with 2.6.28-13).

Hi! Thank you for reporting this problem!
Could you please attach the output of this command: sudo lspci -vvnn > lspci-vvnn.log
Thanks in advance.

I do not use Karamic, but use Jaunty. After kernel update a several days ago my network did not work (WIFI and ETH).

this helped me to solve the problem

sudo /sbin/lrm-manager
sudo modprobe wl

But I think it should be fixed.

Added output of lspci -vvnn

Following the procedure outlined by Anton seems to solve the problem:

Ok, after automatic update to 2.6.28-15: same problem! Is anyone reading these bug-reports???

Solution for me (recalling from memory):
depmod + update-initramfs

Hi all,
Same problem for me with a Dell Studio XPS 16 (Core i7 + Broadcom), I'm using the proprietary driver, each kernel updates breaks the wifi that I must reinstall, boring.

If I can help by providing some technical infos, please, ask.
