Please post the output from:

Code: Select all

rfkill list all
and

Code: Select all

iwconfig
I suppose that's one of the ironies of life, doing the wrong thing at the right moment -C.C.

Run the following and see if it helps:

Code: Select all

sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/*
and then

Code: Select all

sudo systemctl restart NetworkManager

I suspect that there might be something related to:

Code: Select all

Network: Card-1: Realtek RTL8723BE PCIe Wireless Network Adapter
driver: rtl8723be
Alright, please generate a more detailed wireless-info by running the following command in a terminal:

Code: Select all

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw master/wireless-info 

Code: Select all

chmod +x wireless-info 

Code: Select all

./wireless-info
You will find the filewireless-info.txt in your home directory. Copy its content and paste it between </>.
And wait for the cavalry!
Good Luck!

Check this at the end of the post maybe it will be enough to make only the file. Install also and check how it works from 4.4 lts kernel.

Code: Select all

sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be ant_sel=1
Test wireless, if no change then

Code: Select all

sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be ant_sel=2
Test wireless again, one or the other should result in better reception

When you find that one works better than the other

Code: Select all

echo "options rtl8723be ant_sel=X" | sudo tee /etc/modprobe.d/rtlbtcoex.conf
Where X is 1 or 2- whatever resulted in better performance
Then the parameter will be remembered following a restart
