No WIFI presence on Ubuntu 16.04

[K3r0sen]

Brand new HP laptop with fresh Ubuntu 16.04 installation doesn't show WIFI adapter at all on Ubuntu 16.04. I have tried all driver combinations.

When I run <sudo lshw -C network> the output is:

After looking for answers, looks lik "*-network UNCLAIMED" means that there is no driver for that network hardware.

Please advice how to fix WIFI on Ubuntu 16.04

the command for wireless I believe is sudo iwconfig. 

[K3r0sen]

When I run <sudo iwconfig > it says:

"lo no wireless extension.

emp1s0 no wireless extensions"

The idea is that I need to find out the exact needed driver for it.

Do you know the brand of the wifi card?

For example if it is intel you use modprobe iwlwifi

It is a quad core AMD (HP Laptop 15-bw005nq). The manual is here [1] but I haven't been able to precisely identify the wireless card (page 4). Have no idea what linux driver to look for.

I manage to make it work following this [2] but it work very poorly (very very low signal & speed) and I supose that's because is not the right driver. The driver was installed that worked poorly was RTL8723DE and I believe that is not the right one.

Solved thanks to this entry forum [1]. Works like a sharm.

sudo apt-get install git build-essential dkms
git clone -b extended https://github.com/lwfinger/rtlwifi_new.git
sudo dkms add ./rtlwifi_new
sudo dkms install rtlwifi-new/0.6

Reboot.
