I have a HP Pavilion Laptop. The details of which, obtained by running the command lshw, are below:
product: HP Pavilion Notebook (N1J39EA#A2N)
vendor: Hewlett-Packard
version: Type1ProductConfigId
serial: 5CD5291DWT
width: 64 bits
capabilities: smbios-2.8 dmi-2.8 smp vsyscall32
I switched from windows to Ubuntu 18.04 very recently. Initially I did face wifi weak signal issue. However, I fixed the issue by using the following commands:
sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be ant_sel=2
sudo ip link set wlo1 up
sudo iw dev wlo1 scan
echo "options rtl8723be ant_sel=2" | sudo tee /etc/modprobe.d/rtl8723be.conf
Everything was working perfectly and then 2 days ago I updated my system and thereby the kernel got updated which in turn brought back wifi issue.
I tried to fix wifi issue by using the same old method but failed to do so. I also tried the following:
sudo tee /etc/modprobe.d/rtl8723be.conf <<< "options rtl8723be ant_sel=1"
which also couldn't solve the issue. Then I went on to try the following:
sudo -i
echo "options rtl8723be ant_sel=2" > /etc/modprobe.d/rtl8723be.conf
exit
reboot
the same result with same problem. output of the command
lspci -knn | grep Net -A3; rfkill list
