i have read, followed several tutorials and still can't install wireless driver to a Presario 5100 which uses bcm4318 driver. :(
I agree - more input required.
Distro (including version)
Drivers you have tried (including version info)
Other (like does your computer have a wireless on/off button)
Input, Iiiiinput! (Johnny 5)
Have you happened to check if the driver released by BroadComm will work with your Card?
I have a BCM4328 and it works great in 64-bit Ubuntu.
