I have the Realtek rtl8723be driver on my HP-Pavillion Notebook.
While installing Ubuntu 18.04 LTS through plug-n-play option, I tried the following commands before actual installation:
sudo modprobe -r rtl8723be sudo modprobe rtl8723be ant_sel=2
and the wifi was working just fine.
But after installation alongside Windows 10, somehow the wifi stopped working properly, and now only wifi networks very close to the device appear.
I tried installing realtek software from here on GitHub as mentioned in the README. But still no progress.
I even tried changing
ant_sel parameters, then saving them to my
/etc/modprobe.d/rtl8723be.conf and then performing a cold boot. But still no progress.
I also tried installing from this branch, but I got errors.

Can anyone suggest what to do now?
