UPDATE: Uninstalled the drivers and now everything is working fine. Wifi is connecting without any problem now. The audio and bluetooth problem still remains.

Sound settings still shows "Dummy Output" when system is turned on. I have to use alsa force-reload inorder for the audio to work. Bluetooth settings shows No Adapter Found

lsusb for bluetooth shows

Bus 001 Device 004: ID 0a5c:4500 Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of BCM2046 Bluetooth)

I'm using Ubuntu 13.04 and have been trying to get the system to connect to wireless driver. I've installed the drivers from Software Updates -> Additional Drivers but then, under the driver name, it says "This Device is using an alternate driver". I can enable wifi through the indicator in the panel but it doesn't detect any network.

I'm using Broadcom BCM4313 wireless adapter.

There are other problems that I am experiencing, like the "Bluetooth Adapter Not Found" error, and "Dummy Output" in the audio settings.

I have the latest update installed but the issues still remain. The output of lspci is

The wireless issue is the most irritating one. It would be really nice if anyone could help me with the audio problem too. I have tried many solutions I found on askubuntu and ubuntuforums, as well as other websites, but nothing worked.

Thanks.

Provide lsusb for the bluetooth module. Is the audio working after the force-reload? –  grimpitch May 17 '13 at 16:13
    
@grimpitch Updated question with lsusb. And yes, audio works fine after force-reload –  rahules May 17 '13 at 16:18

1 Answer 1

you have first to deactivate the driver you installed from jockey, and then you can use ndisgtk
if you have your wireless driver for windows this program will create a driver for linux starting from Windows driver
if it did not work you can see this for detecting you wireless card then download the driver from here

or finally if those did not worked try this sudo apt-get install firmware-b43-installer or this sudo apt-get install firmware-b43-lpphy-installer in the command line
