I don't see anything wrong with b43. The message shows that your interface is not UP. I use openSUSE and I don't know exactly what the command 'iface' does, but it looks as if something changed there, or in other network support software. Did you make any changes in your system? Perhaps reloading the package that contains iface will fix the problem.
