Using Ubuntu 18.10, I had an issue with a chip-set on my tablet (bluetooth and wifi); upgraded to a newer Kernel fixed the issues. You might want to try Ukuu...it is low risk, still at your own risk, b/c if the new kernel does not work or causes an issue, likely, using Grub menu, revert back to the previous kernel...a newer kernel might fix the issue. I would perform all regular OS updates then use Ukuu. So far, using Kernel 5.0, on my own laptop and tablet, do not have an issue but, experience varies. https://www.omgubuntu.co.uk/2017/02/ukuu-easy-way-to-install-mainline-kernel-ubuntu

You can try the answer on https://askubuntu.com/a/1076824/712349. If that does not work try to find a driver for RTL8822BE on github.

Try this

git clone https://github.com/lwfinger/rtw88.git

cd rtw88/ && make && sudo make install

sudo modprobe -r rtl8723de

sudo modprobe rtl8723de

If all this doesn't work then remove and blacklist the previous driver using the commands given below and then restart -

sudo apt purge bcmwl-kernel-source

sudo sed -i '/blacklist bcma/ d' /etc/modprobe.d/blacklist.conf

sudo sed -i '/blacklist brcmsmac/ d' /etc/modprobe.d/blacklist.conf
