From: Jason Vas Dias To: linux-kernel@vger.kernel.org Content-Type: text/plain; charset=UTF-8 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org After building and installing 3.9.6 kernel & modules on my 2.2ghz HP6715b x86-64 Turion dual core laptop , which has always run Linux with no b43 wireless problems since 2007, now has no access to its onboard broadcom 4311 wireless radio . I had always used the b43 driver with the correct firmware installed under /lib/firmware/b43 with b43-fwcutter as per instructions at http://wireless.kernel.org/en/users/Drivers/b43 , which I've just now redone again, but since booting 3.9.6, which I believe resulted in a firmware download via udev at first boot, the wireless radio "on" blue LED indicator goes off after BIOS POST . It has always been the case that if the blue LED indicator is off after BIOS POST , then the kernel does not see the device, and I have no wireless until a hard poweroff and pressing the touch sensitive wireless on button during BIOS POST. But now the wireless LED goes on for @ 1 second during BIOS POST , and never comes on again , and there are no responses to touching wireless-on button after reboot, though there are to other buttons next to it. In short, I've lost wireless access (and home internet access for my pc - I'm sending this from my mobile) . Can anyone help? How can I force the card to download the re-installed b43-fwcutter firmware, if the device no longer appears in lspci output? Anyway to force the kernel to ignore the wireless button ( it could be that the kernel & bios think this button is in the off state - any way to force its state to "on") ? Any ideas / suggestions would be much appreciated. Thanks & Regards, Jason
