Wifi not working on HP 15-AU114NA on Unbuntu 16.04 LTS

[Guillaume3107]

Hello everybody, I recently purchased a HP Laptop and installed Ubuntu 16.04 LTS.

Since then the Wi-fi does not work.

I have been trying to download new drivers using the standard user interface menus but no luck.

Can someone help me understanding where and how to download the wifi drivers?

Thanks in advance for your support.

So the wi-fi worked in Windows before? Is Ubuntu the only OS on the laptop now? Do you know which wi-fi chip we are discussing here? Intel? Realtek? Broadcom?

Question: So the wi-fi worked in Windows before?

Answer: Yes. And it still works when I use Windows.

Question: Is Ubuntu the only OS on the laptop now?

Answer: no, I have both Windows and Ubuntu installed.

Question: Do you know which wi-fi chip we are discussiong here? Intel? Realtek? Broadcom? 

Answer: Not sure. I searched for some commands in Linux to find out and here is what I typed:

sudo lshw -C network

Here is what I got:

  *-network UNCLAIMED
       description: Network controller
       product: Intel Corporation
       vendor: Intel Corporation
       physical id: 0
       bus info: pci@0000:05:00.0

Actually I realise the terminal response should have something like:

*-network               
       description: Wireless interface

But in my case there is no wirless interface indicated... ?
