For me ant_sel=0 "zero!" was the magic key. Took me a week of messing around until I realized one cannot only select 1 or 2 but also 0. Try out with these:
sudo modprobe -r rtl8723be sudo modprobe rtl8723be ant_sel=0 iwlist scan | egrep -i 'ssid|quality' sudo modprobe -r rtl8723be sudo modprobe rtl8723be ant_sel=1 iwlist scan | egrep -i 'ssid|quality' sudo modprobe -r rtl8723be sudo modprobe rtl8723be ant_sel=2 iwlist scan | egrep -i 'ssid|quality'
