Well, I tried both older kernels earlier today. Same problem with all of them. I think the
driver just isn't cutting it. After thinking about it awhile, I tried my wife's laptop to see if
her wireless works. Amazingly, it didn't work either. On her machine, I had saved the windows
driver that I used with ndiswrapper on pclos 2007 before updating it to 2010.10. Reconfigured her machine with the old
ndis wrapper and it worked first try. Her machine uses a slightly different version of the Broadcom
chip but the native kernel wouldn't work.
Still trying to find a workable solution as I suspect the kernel driver needs some bug fixes or
revisions to work with this particular adapter. Maybe the devs will come up with something.
In the meantime, I am on the hunt for a suitable ndiswrapper solution.
