It same wifi card's chip with mine (RTL8723BE).. first open your terminal and type :

sudo nano /etc/modprobe.d/rtl8723be.conf

and then copy this code :

options rtl8723be ant_sel=1

and then press ctrl+x, choose 'Y' and then hit [enter] now type again the command on your terminal :

sudo modprobe -rv rtl8723be

wait until finish and type again this code :

sudo modprobe -v rtl8723be

and try the wifi to connect to the Access point.

if it doesn't work, try again step by step but change this code: from :

options rtl8723be ant_sel=1


options rtl8723be ant_sel=2


options rtl8723be ant_sel=0

it's work for me, I hope t will work for yout too,,,
