Hello there.
Lately, I've installed the latest version of Ubuntu - 10.10, on my laptop - Lenovo G530, and all work just fine but my Wi-Fi device. Ubuntu cannot even recognize that I have one (it tells that the firmware is missing).
I have figured out that maybe I can fix this with the help of ndiswrapper, but it looks kind of tricky (especially if i don't have windows right now), and I searching for a simple way.
Hope for some usefull feedback :KS

the solution i found for that chipset and so as to be able to use b43 driver is the following

first

sudo apt-get remove --purge firmware-b43-installer

then

sudo apt-get install firmware-b43-lpphy-installer

worked inmediately
