I tried Manjaro MATE and it doesn’t disconnect and then reconnect, but still has very poor range. So something is wrong. In Ubuntu MATE 14.04 LTS i tried something like this:

sudo apt-get install linux-headers-generic build-essential git
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
sudo reboot

It works, still with very bad range, but when I update it breaks :’(
I’m not sure if it works in Ubuntu MATE 16.04 LTS though, but i’ll try it.

But I guess it’s the pain of realtek hardware and drivers

Yep it worked in Ubuntu MATE 16.04 LTS. Still very poor range, but it at least works.
After reboot i had to run: sudo modprobe rtl8723be to get it to work.

But here is the code if you want it, remember to redo this everytime you get an update.

#!/bin/bash
sudo apt-get install linux-headers-generic build-essential git
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
sudo reboot
sudo modprobe rtl8723be

I think maybe people should buy Linux compatible hardware and devices to avoid these problems. System76 computers should be good enough for some people. Avoid Realtek, Waves MaxxAudio, AMD and NVIDIA stuff in my opinion. Better Qualcomm Atheros/Atheros and Intel

Try this (install through ppa): https://askubuntu.com/questions/629679/rtl8723ae-unstable-on-ubuntu-14-04

It doesn’t completely fix the problem, at least for me, but you don’t have to do the above procedure everytime you update.

I’ll give that a try when i’m not busy :slight_smile:

Everyone here with the driver rtl8723be, did you try to kill power savings to the wifi adapter using the following commands?

echo "options rtl8723be fwlps=0" | sudo tee /etc/modprobe.d/rtl8723be.conf
sudo modprobe -r rtl8723be
sudo modprobe rtl8723be

Issue the first command only once as it should persist across reboots.

Also in the future please avoid posting further questions into "solved" threads such as this one as it lacks visibility, instead open a new thread so helpers can focus on your specific problems.
Cheers
