From your above output. There is something drastically wrong if your system is loading the Broadcom WL driver for a Realtek chipset. I would look in the Garuda Hardware manager app and uninstall any Broadcom WL driver listed there.
You can run this command to temporarily unload the wl module:
sudo modprobe -r wl; sudo modprobe -r rtl8723be; sleep 3; sudo modprobe rtl8723be; sleep 3; sudo systemctl restart NetworkManager
I would also disable MAC Address randomization. This should be an easily selectable option in the Garuda network utility (or search online for directions).
Unfortunately, that is one of the more problematic Realtek adapters that you own. I’ve probably answered a hundred or more help requests on that adapter. Fortunately, it is becoming more well supported as the driver matures on the newer kernels. It still has a fair share of issues though, as its not a great adapter (but reliability is improving for it).
