[Bug 268625] Re: Intrepid: Regression Ndiswrapper is broken by b43 driver again

[Atanas Atanasov]

I am not precisely sure about the reason but I am experiencing a similar
problem. I am using Intrepid on a Dell Inspiron 1721 with Broadcom 4328
wireless card. I have been using ndiswrapper for a long time without any
problems and it suddenly stopped working yesterday. It seems that
ndiswrapper is installed properly, the module is loaded but it is not
used for the wireless card in any way. I do not see the wireless adapter
with ifconfig, despite the fact b43 is blacklisted (it still loads?).
Below are some output you might find useful.

blacklist b43
blacklist b44

I do not understand how it is possible to blacklist b44 and still have
it present. When I run "modprobe -r b44" my network stops working
altogether.

Do you have any ideas how to fix this?
