How to make the effect of these commands permanent so that it persists even after rebooting?

sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be ant_sel=2

Note: echo "options rtl8723be ant_sel=2" | sudo tee /etc/modprobe.d/50-rtl8723be.conf does not work.

I followed this tutorial to solve a problem with weak wi-fi signal.

  • If the module is loaded at initramfs time, so you should run `sudo update-initramfs -u -k all` after the `echo "options rtl8723be ant_sel=2" | sudo tee /etc/modprobe.d/50-rtl8723be.conf` command – pim Nov 17 '17 at 09:24

You have a second conf file in /etc/modprobe.d/ telling it to use ant_sel=1 

sudo rm /etc/modprobe.d/rtl8723be.conf
Reboot

  • That configuration file is most probably a leftover from all the way back when I was using 16.10. In both 16.10 and 17.04 the antenna that worked was 1, but in 17.10 it became 2 for some reason which I don't know. – Tooniis Nov 20 '17 at 13:30
