Ubuntu – WiFi problem with hp probook


I have a hp probook 470 G2 on which I have Windows and Ubuntu installed.
WiFi works on Windows but not on Ubuntu. At start up I get this message :

rtlwifi: Firmware rtlwifirtl8723befw.bin not available.

Could you please help me fix this problem?

The output of lspci -knn | grep Net -A2 is :

09:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:b723]
    Subsystem: Hewlett-Packard Company Device [103c:2231]
    Kernel driver in use: rtl8723be
