I am using HP bs179tx.
I have installed Ubuntu 14.04 but I am not able to get my Wifi working.
It has Realtek driver installed in it
I do not see the option Enable Wifi in the network bar.
The HP BS179TX laptop comes with Realtek WiFi Hardware. The Network controller is Realtek Semiconductor RTL8723DE Device d723.
The linux driver for this device is not directly available. But, according to the discussion "Realtek 8723DE wifi module" in HP Support Forum, the RTL8723DE officially supported driver is made available in the repo : rtlwifi-new git extended branch .
You can find the installation instructions here
Please follow this link . The wifi drivers might be deactivated. You have to enable it manually.
