I just installed Ubuntu 11.10 Desktop on my Windows 7 Laptop (Lenovo B570).

Wired connection works fine, but I'm not able to even switch wireless on.

As soon as I click the wireless button from off to on, it goes back to off automatically.

Tried looking online for answers, not able to find anything.

Any help is appreciated, thank you!

  • Please post the output of sudo lshw -C network. Just to know, when you say "I clicked it form off to on", do you mean marked the checkbox next to "Enable Wireless" in the "connection inidcator"?

  • What is the output from: iwconfig?

add blacklist acer_wmi to your /etc/modprobe.d/blacklist.conf , for example:

sudo -s
echo "blacklist acer_wmi" >> /etc/modprobe.d/blacklist.conf

and restart your computer.

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.
