Hp laptop doesn't wifi on Ubuntu

[jeremy31]

One thing surprised me,it named the file rtl8723be.ko.1, so

cd /lib/modules/4.15.0-33-generic/kernel/drivers/net/wireless/realtek/rtlwifi/rtl8723be
sudo mv rtl8723be.ko rtl8723be.ko.bak
sudo mv rtl8723be.ko.1 rtl8723be.ko

Reboot

The strange thing is that Ubuntu is the third system I installed in this pc. First I installed Kubuntu and wifi was not working at the beginning, but asking on this forum seems that wifi card was just needing to be activated. Then at certain point wifi card stopped to work, so I tried to use Manjaro, but the issue wasn't able to be fixed. Then I tried with Ubuntu and the problem still here. Is that probably not a problem of system but something I must set from the pc's uefi/bios? I tried to see and wifi is abled in there.

The RTL8723BE chipset works fine in Linux, at least with some kernels and the use of ant_sel=2 with some HP laptops because HP decided to only use one antenna wire instead of two. The issue with 4.15.0-33 is that an upstream commit was included that messed up the antenna select feature

So, what should I do now?

So, what shoul I do to fix this problem?

I don't understand, I downloaded and installed all the links then what you mean for "change into the directory"? Using that code it gave me an error, what have I to do to?
