I have recently installed ubuntu studio 13.04 on my netbook. It is excellent, but i have some problems with my WiFi.

If I use the command lspci I can see that I have a Broadcom bcm4313 wireless card installed. If I run the command iwconfig there is no wlan0!

It seems that Ubuntu does not pick up the WiFi card or the card is blacklisted.

Please do some basic troubleshooting first. And edit your question to include more specific hardware information. My WiFi adapter is not working at all. Where to start troubleshooting? –  gertvdijk Oct 15 '13 at 10:03

In Ubuntu 13.04, I believe the default bcmwl-kernel-source will not work correctly for your Broadcom 4313. I recommend that you get a temporary wired ethernet connection and open a terminal:

sudo apt-get remove --purge bcmwl-kernel-source
wget http://us.archive.ubuntu.com/ubuntu/pool/restricted/b/bcmwl/bcmwl-kernel-source_5.100.82.112+bdcom-0ubuntu3_amd64.deb

Or, if yours is a 32-bit system:

wget http://us.archive.ubuntu.com/ubuntu/pool/restricted/b/bcmwl/bcmwl-kernel-source_5.100.82.112+bdcom-0ubuntu3_i386.deb

Confirm 32- or 64-bit:

arch

Then do:

sudo dpkg -i bcmwl*.deb

Reboot and give us your report.

Check if you can install the driver going to "Software & updates" (search in the dash) and then to the "Additional drivers" tab. Otherwise, you can to manually install the Proprietary Broadcom STA Wireless driver (assuming you have wired internet connection) with: sudo apt-get update && sudo apt-get --reinstall install bcmwl-kernel-source stop any other driver working: sudo modprobe -r b43 ssb wl brcmfmac brcmsmac bcma and load the driver with: sudo modprobe wl
