That is easy

echo "options rtl8723be ant_sel=1" | sudo tee /etc/modprobe.d/rtlant.conf

It is the same for any module parameter options {module-name} {parameter-setting} use sudo tee -a if a file exists and you just want to append to the file. Parameter options need to be in /etc/modprobe.d/{whatevername}.conf


Stop doing those things, follow this guide and it will work for you.

I have the same card as you, but another model (different numbering) and this guide solved all the problems I had with wifi.

You are lucky that the guide is the same as for your card, I had to change some numbers for mine.
