Booting with the previous linux image 4.7.5.1 and after setting firmware swtich fwlps to off , seems that established a rigid connection.
Maybe the new kernel 4.7.6.1 is more "sensitive" on the FW flags, since i had never issues before with fwlps which had been left to it's default value (1) for a lot of months. Maybe i could try to upgrade again in the new linux-image 4.7.6.1 and see how it performs with fwlps off. I switched off fwlps by using echo "options rtl8723be fwlps=0">/etc/modprobe.d/rtl8723be.conf (or could be done by adding above line in the end of the existed modsetting.conf file in the same directory). PS: All the rest options of rtl8723be are left to default. George V.
