Firmware - SOLUTION

I had the same problem. When I would try to do:

$ sudo ifup wlan0

I would get: SIOCSIFFLAGS: No such file or directory.

When I typed in:

$ lspci | grep Network

I got: Network controller: Broadcom Corp BCM4318 ...


It turns out this is a common problem for Broadcom cards. (The "B43") I am running Ubuntu with Fluxbox and using WICD. WICD wouldn't even list my wlan0, and therefore wasn't showing any networks in the area. I finally got it working by going to:

http://linuxwireless.org/en/users/Dr..._and_b43legacy

and following the instructions for my distribution. All I did was:

$ sudo apt-get install b43-fwcutter

It asks if you want to download the firmware at the same time. I said yes, it installed, I restarted, and it worked. (WICD was able to find networks and connect.) I have been trying to fix this for awhile, so I hope this reply to an old thread still helps someone.
