Realtek 8812BU wifi adapter query

[crazydruid]

I've been running Sparky Linux 6.4 Stable (Kernel 5.15.62-sparky-lts-amd64) this last week and I have been very pleased with it. I installed it on an old Acer Aspire ES11 (ES1-131-C)XB) but the wifi on the internal adapter is a bit slow for some reason so i tried using a spare usb Realtek adapter (8812BU).After searching about online for info, I manged to get it working via the following:

sudo apt update
sudo apt install -y dkms git bc
git clone -b v5.8.7 https://github.com/fastoe/RTL8812BU.git
cd RTL8812BU
make
sudo make install
sudo reboot

This gets the adapter working but after a couple of restarts/shutdowns, it fails to get recognised/start so i have to go through the above process again to get it up and running. Once it does start, it works well and is far faster than the internal wifi adapter. I am no Linux expert so could this be the result of me using the wrong kernel or something? Appreciate any information.

Kind regards.
