BIOS usually controls this sort of thing. Check "rfkill list" and see if you have a "platform" killswitch. On my HP, that looks like: 0: hp-wifi: Wireless LAN and when that is blocked, it hardblocks the internal wifi. This switch is provided by a small driver that talks to your laptop's BIOS. It's likely that either your laptops device IDs are not added to the correct kernel driver, or your laptop does things in a different way than previous ones, and doesn't have a kernel driver yet. But in the end, this is most likely a kernel rfkill driver bug, not a wifi bug. What make and model of laptop is this?
