*** This method is only applicable to rtl8723be drivers and for Ubuntu users ***
Recently I was having an issue with my laptop which supports rtl8723be driver. It was not getting connected to WiFi network. Then I searched a lot and got a solution for it, although it is not permanent but still it will work for two lines of code 🙂
For continuing this process you must do the following things :
First of all go to bios setup and then follow –
System configuration -> Boot option -> Secure boot -> Disable
Then you need to install rtlwifi-linux-firmware, open your terminal and follow these codes
$ sudo add-apt-repository ppa:hanipouspilot/rtlwifi $ sudo apt-get update $ sudo apt-get install rtlwifi-new-dkms linux-firmware
*set your country code( like for India – IN )
$ sudo iw reg set 'your country code'
Do restart your computer once the country code is set
$ sudo iw reg set IN
Now go to the given link and download or clone the zip file from Github. Also extract that file in your home terminal.
Follow these codes :
$ sudo apt-get install linux-headers-$(uname -r) gcc g++ build-essential dkms git (try to install one by one) $ sudo reboot $ cd rtlwifi_new-rock.new_btcoex $ make $ sudo make install $ sudo modprobe -rv rtl8723be
Now copy these following code in your terminal
$ sudo modprobe -v rtl8723be ant_sel=2 $ sudo modprobe -r rtl8723be
$ sudo modprobe rtl8723be
Now your system will be okay with WiFi.
To make it permanent follow these codes :
$ echo "options rtl8723be ant_sel=2
fwlps=0" | sudo tee /etc/modprobe.d/rtl8723be.conf
Hope it worked 🙂
If any problem occurred then please do a comment.
