Comment 10 for bug 712053

This seems similar to bug #732677. The difference is that you have bcmwl 5.60, and I think natty is meant to use 5.100. I believe the differences are simply due to the fact that you installed natty from a very early pre-release daily live image.

It's likely if you do a clean natty install from a more mature natty image (say beta-1, or tomorrow's beta-2), then you will end up with brcmwl 5.100. In the best case, wireless will work. In the worst case, this bug then becomes a duplicate of #732677. Sorry to not be more helpful.
