Realtek RTL8723BE drop connections issue in GNU-Linux systems.

The Realtek RTL8723BE wireless (WiFi) card, it's assembled in many lower-hight end laptops, a sample Lenovo G50-45, unfortunately default module setup drops network connection (<kernel 3.13) with APN, which is annoying, enforce us to bring up the network each time it happens.

Fortunately the solution is so easy, the only thing we need to do is putting this command line into a terminal. The problem is caused by the card power saver driver:

echo "options rtl8723be fwlps=N ips=N" | sudo tee /etc/modprobe.d/rtl8723be.conf
You will need super user rights to create configuration file, it will ask for administrator password.
Then the easy way is reboot the computer, once computer start up it will load the new configuration auto.
If you don't want reboot, follow the next steps....

Type:

rmmod rtl8723be 

then:

modprobe rtl8723be fwlps=N ips=N

Finally your card is ready !!!

  1. Thanks for the post
    I had followed those steps several times, but after a while connection is dropped again. Sadly, this is an issue because the laptop's owner is a non-technical person.

    The laptop is a Lenovo B50-70
    Debian Jessie
    Kernel 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u6 (2015-11-09) x86_64

    any advice?

    Thanks in advance

  2. First of all install lshw utility to check brand name and model, you can use "dmesg" as well:

    sudo apt-get install lshw

    Then:

    sudo lshw

    Check your wireless (product,vendor and driver) and post it.

    I tested on Lenovo G50-45 (Jessie and Testing/Sid) and works like a charm, but i need to be sure we are using the same wireless hardware.
