i have googled and searched the forum but cant figure this one out

i use ubutnu 8.1 and bt3 from live usb and i cant connect to the internet
only interface i can find is lo and that one doesnt do much

i tried updateing kernel first downloaded it in ubuntu the from bt3 ran lzm2dir kernel.lzm / and nothing

tried using ndiswrapper to install drivers and i did install it but again nothing
and i tried to manually upgrade with unpacking and packing lzm but i got some system errors

i use acer aspire 5730zg with acer nplify 802.11b/g draft-n wlan this is a new machine and i guess the driver for my card isnt in the original kernel of bt3 so i figure i have to get it upgraded

is that right? and can someone help?
