Comment 12 for bug 573273

*****Do this first******

I see what went wrong above. After removing the device and sudo rmmod rndis_wlan, could you also retry

sudo sh /usr/share/b43-fwcutter/install_bcm43xx_firmware.sh

The sudo is imperative, and so is the space between sh and /usr...

Then, plug it back in. If that doesn't work, try the instructions in the above post from the very start again.

I'm really sorry that I've made this so mixed up, but I'm confident there's a way to make this work! We need to try it before formalising the bug, anyway. Thanks for your help!
