I have a Broadcom 802.11 wireless pci card in my laptop, chipset 4318. I have followed all the instructions to replace the delivered driver with ndiswrapper with the appropriate Windows driver bcmwl5. I've just loaded Ubuntu so the kernel is 3.5.0-17. I had to use ndiswrapper-1.58rc1 to circumvent a problem with modprobe but now when I follow all the steps given for install ndiswrapper I get no errors but still no luck. Driver b43-pci-bridge is listed in /etc/modprobe.d/blacklist.conf but it is still the driver associated with the device according to lshw and I can't find any reference as to where that association is being made. When Ubuntu boots the wireless assistant button on the keyboard is not lit and I can't find any combination of keys or command to get it to light, I assume because the installed driver is wrong. So in short Ubuntu help - Wireless trouble shooting has used up the better part of 3 days but still not produced the desired outcome. Any ideas? I'm sure that if I could find out where that driver is being associated with the device I could make ndiswrapper work instead.
Ndiswrapper is the least desirable option, in my opinion. Please get a temporary wired ethernet connection, open a terminal and do:
Your wireless should now be working.
