Ok then do

Code: Select all

echo "options rtl8723be ant_sel=2" | sudo tee /etc/modprobe.d/rtl8723be.conf
Reboot and it should work.

I found the cause of the issue, to fix do

Code: Select all

cd /usr/src/rtlwifi-new-0.6
sudo rm dkms.conf
sudo wget https://github.com/jeremyb31/rtlwifi_new/raw/master/dkms.conf
sudo sed -i 's/PACKAGE_VERSION=0.7/PACKAGE_VERSION=0.6/' /usr/src/rtlwifi-new-0.6/dkms.conf
And it should work in future kernel updates
