Early today install Linux Mint 18.1 to a laptop that comes equipped with a Wifi Card Realtek rtl8723be, everything was normal until after a while the wifi was disconnected and did not connect again. I have spent several hours trying to correct this problem until I got the solution from the hand of Roopansh Bansal you have made a little bash script that fixes the problem.
In the same way, delving into the Roopansh solution, I have achieved that there is another solution by executing a single command (which is incorporated in the Roopansh script), so I leave both solutions for everyone to use in case they present this error.

Solutions to Realtek rtl8723be Wifi Card problems
Solution 1: Using the Roopansh Bansal script
This simple allows us to solve the problem of our Wifi card, it is the solution that worked for me and that has made the card behave stable and without any problem.
To carry out this solution, open a terminal and perform the steps indicated below.
- Clone the official repository of the script
git clone https://github.com/roopansh/rtl8723be_wifi
- Go to the directory where the repository was cloned
cd rtl8723be_wifi
- Execute the following command, to start the installation of the solution.
bash rtl8723be.sh
- Restart your computer and start enjoying the stability of your Realtek rtl8723be card.
Solution 2: With a single command
This solution is faster and easier, the original source of this solution can be found here.. Just open the terminal and run the following command:
echo "options rtl8723be fwlps=0" | sudo tee /etc/modprobe.d/rtl8723be.conf
I hope these couple of solutions help you solve the problems you have with your Wifi card. It is worth noting that if you have any other solution to this problem, you can leave it in the comments and we will gladly add it to the article.
Did you read all the askubuntu tl correctly? did you find out that this solution causes kernel panic's? And that when the kernel is updated the .conf of the module causes conflicts, that you have to remove it, download the module, upload it again, and rewrite the .conf so that it works again and that the kernel panic can still happen? , read the forums well before recommending anything.
Both the majority of askubuntu users and me have worked correctly and without any kernel panic, even in the Ubuntu ask only one person says it happened at some point and the cause is unknown. The solution is efficient and so far it has not brought me any problem ... Have you tried testing the solution?
I have been using this solution for more than two years (I have installed Ubuntu several times because I like to be a handyman) and so far it has not given me any inconvenience. Greetings.
Broadcom issues are mostly fixed with this package

Thank you very much for publicizing the solution, in any case it would always be appreciated to comment a little on the functionality modified by the option used in the command. In the case of fwlps = 0, what is done is to deactivate the energy saving, which may be important if it is used in some Wi-Fi integrated in laptops, since it might be better to deactivate the Wi-Fi directly when it is not going to be used while it is being used. use the battery, at least while trying to fix the bug.
Thank you, I had been suffering for days due to the poor performance of the wifi, I came to think that it was a problem of my Internet company since of the 20MB that I have contracted in my Ubuntu Mate I could only make use of 3 - 5 MB doing a speed test, I just run this solution and problem solved.
Thank you very much, it works perfect for me. I also have a problem with the sound, I don't know if you can help me ... Sometimes I have sound when I turn on the laptop and sometimes not. What can be?
Thank you very much it worked perfect for me on linux mint
Hello
the version of the driver in this repo, no longer has a problem and works fine.
https://github.com/HuayraLinux/rtl-8723-dkms
You can port the package to ubuntu.
Regards!
Thank you very much for the Post! On my HP 14 ac-111la it worked perfectly! Greetings.
I have installed Ubuntu 16.04 along with Win10 on a new HP laptop and I can't get the wifi to work properly. The signal is quite weak when I move away from the router ... I have used method 1 that you indicate (the Roopansh Bansal script) and I get an error:
modprobe: ERROR: could not insert 'rtl8723be': Required key not available
What key is he talking about? I would appreciate some advice to solve this, I have been thinking about it for several days and I do not want to send Ubuntu for a walk, I have been using it for years on another old laptop and I do not get used to Windows ... Please, help :: crying ::
I finally solved it! The problem was that it was still enabled in damn Windows Secure Boot, which asked me for a password to be able to execute these commands.
Anyway, none of the solutions given in this blog have worked for me. The explanation that, followed step by step, has given me good results has been this link:
https://askubuntu.com/questions/717685/realtek-wifi-card-rtl8723be-not-working-properly/
I hope that any of these three options will help everyone who encounters this problem again!
Luck!
Thank you very much for the solution.
I have a hp an014la laptop to which I installed elementary OS and I had already been breaking my head for several days when I could not find a solution and with this it worked.
Thanks in advance, greetings from Mexico.
Hola!
Thank you very much for the solution, but in my case it has remained the same with solution 2, is it possible to undo 2 to try other options?
Hi there!!! you have saved my life champion of champions !! The first of the solutions worked for me, I have been with this problem for days and this post has helped me a lot thanks a lot haha
Good afternoon friends! As many of you have problems with the power of the RTL8723BE driver, I tell you that I installed them in Ubuntu xfce 16.04 and it worked fine until kernel 4.10, when I update to 4.13 it stopped working, I tried several scripts and nothing. The solution for now is to stay on kernel 4.10. The same thing happened to me in distributions like debian or fedora. My notebook is HP 240 g5.
Good,
Thanks for the possible solutions, but after having made both options, I still have the same problem. I will try to recover kernel 4.10.
Thanks, I think that I am finally here, now I can use Linux without the need for an external antenna
