The Wifi isn't working, I'm not able to create a new (wifi) connection in the Network Settings.

As mentioned in this answer I should ask a new question, if I have PCI ID that's not listed and well sadly I've got one : 14e4:43ae. I'm running the newest version of Ubuntu. uname -r returns 4.2.0-18-generic.

sudo lspci -vnn

The output of sudo lshw | grep wireless is empty.

EDIT: I'm now really getting annoyed by this Broadcom Chip! Anyway, I ordered an Intel Wifi Chip and I'm going to replace my current with it.

  • Same problem here (although on Arch, but it's all roughly the same kernel). Lenovo Yoga 500 14" laptop. – Thomas Dec 15 '15 at 11:01
  • The official Broadcom driver ("Linux® STA 64-bit driver"), of which bcmwl-kernel-source is just a repackaging, does not see this device. The PCI device ID is not in any database that I can find, either... did you have any success at least identifying the name of the chip? – Thomas Dec 15 '15 at 11:54
  • No, sadly not... – Nico Hauser Dec 15 '15 at 12:56
  • Meanwhile, I think I've found it's a BCM43162. Which is indeed not listed as supported (or unsupported) anywhere that I could find. I tried ndiswrapper as well, but apparently the driver I threw at it was for too new a Windows version, because it complained about a lot of undefined symbols. I've given up for now as well, and I hope Linux support for this chip will appear some day. – Thomas Dec 15 '15 at 13:38
  • Hmm well thats unfortunate.. If I had the time I would try writing the driver by myself but I think it's easier (and probably quicker) to buy a supported wifi chip... – Nico Hauser Dec 15 '15 at 21:44
