I just bought this brand new lenovo B570 last week and the first thing I did was install Ubuntu 11.10 but whenI tried to connect it through a wireless connection it just didn't at all. How can this be solved? I really love Ubuntu and it would be a massive disappointment if this can be solved. Thanks!
I have the same laptop (b570) and had a difficult time. Hopefully you have dual boot with windows. In my case I had to blacklist acer-wmi in the document "/etc/modprobe.d/blacklist.conf" (at the bottom type in "blacklist acer-wmi" without quotes) then reboot back into windows and turn on the wireless, reboot back into Ubuntu and it worked.
I had tried for days with just blacklisting, then messing with the hardware switch on the actual case, tried the fn key and most everything I could google with no luck. Then upon needing wireless booted into windows realized it was off there too, turned it on, back into Ubuntu 11.10 and fixed.
I found the solution from: http://ubuntuforums.org/showthread.php?t=1871781
