I installed ubuntu 12.04 LTS 3 days ago and since then wireless feature and touchpad gestures are not working. Tried everything on internet but still unsuccessful. I cant upgrade to ubuntu 12.10. These are the following comments I tried. Please help me.

EDIT: just realized usb 3.0 is also not working.
