I know this is a common question, I've search and tried many solutions already. The thing is When I tried ubuntu with live cd, I can use my wifi although I needed to go to Software source to enable a setting. But after I actually installed Ubuntu It doesn't work anymore. I can't even enable that setting. This goes without saying that I'm a noob. Thanks.

There are bugs concerning wifi in recent kernel drivers . Please check if you're affected, e.g. In any case you should report a bug. Wifi should simply work. If your bug report will be valid you'll most probably get assistance directly on launch pad.

Have you enabled the propriety drivers if there are any available for your device? Try following steps given in step 7 here . If it doesn't work run


and post output.
