Can any body tell me how to start my WiFi? It is not working with 11.04. I am new to Ubuntu. Please any body give me the code to compile and how it will work. I am really stuck with this problem.

My laptop model is Lenovo B570e. Please help me out.

If you are new to Ubuntu, then why do you install an old version? 12.04 is the current release, 11.04 may not support your hardware properly. Also, please don't tag your question with unrelated topics. – gertvdijk Sep 16 '12 at 11:19
Download Ubuntu Precise Pangolin 12.04 and try it again. – BuZZ-dEE Sep 16 '12 at 12:36

11.04 is going to be End of Life by the end of this month, anyways, so 12.04 is a better version to try. – Thomas Ward Oct 10 '12 at 17:03

I have a Lenovo v570 and I had the same problem. Perhaps what worked for me will work for you.

Try this: sudo rmmod -f acer-wmi

Once that's done your wifi should just kick on, if that is the cause of the problem. If that does work, you can make that permanent by creating a blacklist for it:

sudo touch /etc/modprobe.d/blacklist-custom.conf

Then use nano or vi/vim to open the file /etc/modprobe.d/blacklist-custom.conf and write this line to that file: blacklist acer-wmi. That will keep that module from loading when you start your computer.

Again, this is what worked for me when I had that problem. I hope it helps.
