    What results for
    Code:
    modinfo rtl8723bu
    For bluetooth do
    Code:
    cd /lib/modules/4.15.0-20-generic/kernel/drivers/bluetooth/
sudo mv btusb.ko btusb.ko.bak
sudo wget https://www.dropbox.com/s/uoovkbe7chgh00p/btusb.ko
    Reboot and see if bluetooth works

    What about
    Code:
    modinfo 8723bu
    Did you run the third command for the bluetooth after
    Code:
    cd /lib/modules/4.15.0-20-generic/kernel/drivers/bluetooth/

    To fix the 2 interface issue
    Code:
    sudo sed -i 's/EXTRA_CFLAGS += -DCONFIG_CONCURRENT_MODE/#EXTRA_CFLAGS += -DCONFIG_CONCURRENT_MODE/' ~/rtl8723bu/Makefile
cd rtl8723bu
make clean
make
sudo make install

    Wifi now has only one option and connected successfully and Bluetooth has been activated...but still cannot connect to any device. Phone, Handset. Anything.

    Re: Ubuntu 18.04: Edimax EW-7611ULB WiFi/Bluetooth USB not working

    Ok, lets add to the wifi so it won't have to be compiled after every new kernel
    Code:
    sudo apt install dkms
sudo dkms add ./rtl8723bu
    What are the results for
    Code:
    dmesg | egrep -i 'blue|firm'
