I just loaded Ubuntu 9.1 onto a Dell Inspiron 2200 laptop. This laptop has a built in Wifi Card. I have read that others have been able to get this laptop wifi card working in linux but I am not having any luck. I loaded the correct driver using ndiswrapper and my lshw shows:

One odd thing that I noticed is that it appears that the wireless driver is b43-pci-bridge but the real driver's name is bcmwl5.inf I reinstalled the correct driver in ndiswrapper and did a restart but the lshw shows the same info.

Any help is appreciated. I have been wrestling with this for a few days.

You don't need ndiswrapper. Linux has a native driver, called b43, which is included. What you need is some non-free firmware. If you have a wired connection, do
But remove ndiswrapper, or blacklist the module from loading, or it may conflict with the native driver.

Oh, and FWIW, I have the same card on a laptop and Fedora 12 worked out of the box when I tested it, using the new open source firmware.
